Selling a Split Level Property: Valuations, Mortgages and Buyer Appeal
How split level layouts affect buyer interest, valuations, and mortgage applications. Practical advice for sellers on marketing, surveys, and conveyancing.
What you need to know
Split level properties have rooms on staggered half-floors connected by short internal staircases rather than a single flat plane per storey. This layout affects who will buy, how lenders assess the property, and how long the sale may take. With accurate pricing, targeted marketing, and thorough preparation of legal documents, split level homes sell successfully.
- Split level properties appeal to a narrower buyer pool because the internal steps deter families with young children, older buyers, and those with mobility needs.
- Most mainstream mortgage lenders will lend on a split level property without layout-specific restrictions, though non-standard construction alongside the split levels can complicate applications.
- Accurate pricing is critical — overpricing a split level property leads to extended marketing times because the buyer pool is already smaller than for a standard layout.
- Floor plans and 3D virtual tours are especially important for split level marketing because the layout is hard to convey through standard photographs alone.
- If the split levels were created by a conversion, building regulations approval and structural documentation should be available for the buyer’s solicitor.

Check your sale readinessSplit level properties are a distinctive part of the UK housing stock. Found in purpose-built developments from the 1960s and 1970s, in conversions of older buildings, and in homes designed for sloping sites, they offer a layout where rooms sit on staggered half-floors connected by short flights of steps. This design creates natural separation between living spaces — a quality that some buyers find highly appealing and others find impractical.
If you are selling a split level property, understanding how the layout affects buyer interest, mortgage applications, valuations, and the conveyancing process will help you prepare effectively and set realistic expectations. This guide covers every aspect of selling a split level home in England and Wales.
What is a split level property?
A split level property has its internal floor levels staggered at different heights rather than aligned on a single horizontal plane per storey. Instead of walking from room to room on the same level, you move between half-storeys via short internal staircases — typically three to six steps at a time.
Split level layouts arise in several ways:
- Purpose-built design. Many split level houses and flats were built in the 1960s and 1970s when architects favoured the style for its efficient use of space and visual interest. Local authority housing estates from this era frequently include split level maisonettes and houses.
- Sloping sites. Properties built on hillsides or sloping plots often use a split level design to work with the natural gradient, avoiding the cost and disruption of extensive earthworks to create a flat building platform.
- Conversions. Some split level properties result from the conversion of older buildings where the original floor levels did not align — for example, where two adjoining buildings at different heights were combined into a single dwelling, or where a loft or basement conversion created a new half-level.
- Modern architectural design. Contemporary architects sometimes use split levels to create open-plan living spaces with defined zones — for example, a sunken living area adjacent to a raised dining platform.
The common thread is that the property has more than two distinct floor levels within what would otherwise be a single- or two-storey building. This design has implications for how you sell the property, who is likely to buy it, and what lenders and surveyors will focus on.
How a split level layout affects buyer interest
The split level layout divides opinion among buyers more sharply than almost any other property feature. Understanding who is in your likely buyer pool — and who is not — is essential for pricing and marketing.
Buyers who are attracted to split level homes
- Couples and professionals who appreciate the natural separation between living areas, home offices, and sleeping spaces without needing a larger property.
- Buyers who value architectural character. Split level designs, particularly those from the mid-century modern era, have a dedicated following among buyers who seek homes with distinctive layouts.
- Families with older children who benefit from the zoning that split levels provide — teenagers can have their own semi-separate living space on a different half-floor.
Buyers who may be deterred
- Families with young children are often concerned about the safety of internal steps. Stair gates are harder to fit on open-plan split level staircases, and the multiple changes in level create hazards for toddlers.
- Older buyers and downsizers who are seeking step-free or single-level living. For a comparison, see our guide on selling a ground floor flat, which appeals to accessibility-focused buyers.
- Buyers with mobility impairments or those who anticipate mobility issues in the future. The internal steps in a split level property are difficult or impossible to adapt with a stairlift, unlike a conventional staircase.
This narrower buyer pool does not mean a split level property is unsellable — it means you need to price accurately and market to the right audience from the outset. Overpricing a split level property is a common mistake because it extends the already longer marketing period.
Valuations and pricing
The effect of a split level layout on property value varies considerably depending on location, design quality, and local buyer preferences. There is no universal discount or premium.
| Scenario | Typical impact on value vs standard layout |
|---|---|
| Well-designed split level in an area with architectural appeal | Level with or modest premium |
| Purpose-built 1960s/70s split level in good condition | 0% to 5% discount |
| Split level in a predominantly family buyer area | 5% to 10% discount |
| Awkward or poorly executed split level conversion | 10% to 15% discount |
| Split level with additional non-standard features (e.g. flat roof, unusual construction) | 10% to 20% discount (cumulative factors) |
The most important step is to instruct an estate agent who has experience with split level properties in your area. They will be able to identify comparable sales and advise on realistic pricing. If comparable split level sales are scarce locally, your agent may need to look at a wider geographic area or adjust from sales of similarly sized standard-layout properties. For a full picture of selling costs, see our guide on conveyancing costs.
Mortgage lender considerations
One of the most common concerns among split level property sellers is whether the buyer will be able to secure a mortgage. The good news is that most mainstream UK mortgage lenders do not have specific restrictions on split level layouts. The lender's surveyor assesses the property on its overall condition, value, and marketability rather than the number of internal levels.
However, there are situations where a split level property may face additional lender scrutiny:
- Non-standard construction. Many split level properties from the 1960s and 1970s were built using non-traditional construction methods — such as concrete panel systems, steel frames, or pre-fabricated components. If the construction type is classified as non-standard, some lenders will decline or impose conditions regardless of the layout.
- Unconventional conversions. If the split level design results from a conversion that does not have building regulations approval, lenders may be reluctant to lend. The buyer's solicitor will check for compliance certificates as part of the conveyancing process.
- Low marketability. If the lender's surveyor considers the property difficult to resell — for example, because the split level layout is extremely unusual or the buyer pool is very small in that area — they may down-value it or recommend a retention.
- Combined issues. A split level layout on its own is rarely a problem, but when combined with other factors that lenders scrutinise — flat roof, above commercial premises, short lease (for leasehold properties) — the cumulative effect can make lending more difficult.
As a seller, you cannot control your buyer's mortgage application, but you can help by having documentation ready that confirms the property's construction type, any building regulations approvals, and the structural integrity of the split level design.
Survey findings in split level properties
When a buyer commissions a survey on a split level property, the surveyor will focus on structural integrity and the junctions between different floor levels. Understanding what the survey is likely to highlight helps you prepare and reduces the chance of post-survey complications.
Common survey findings include:
- Stepped cracking. Diagonal cracks that follow the mortar joints at points where different floor levels meet the external walls can indicate differential settlement — where one part of the building has moved differently from another. This is more common in split level properties because the foundations may be at different depths.
- Damp at level changes. Where floor levels change within the building, the junctions between walls and floors can be complex. If waterproofing or damp-proof membranes are inadequate at these junctions, damp can penetrate. This is especially relevant in properties with below-ground sections.
- Structural adequacy of internal steps. The surveyor will check that internal staircases and the floors they connect are adequately supported. In conversions, the structural work to create split levels may not always have been carried out to building regulations standards.
- Fire escape routes. Split level layouts can complicate means of escape in the event of a fire, particularly where the route from bedrooms to the front door involves navigating multiple changes in level. The surveyor may note concerns about fire safety, especially in older properties that pre-date current building regulations.
- Sound transmission. In split level flats, the staggered floor levels mean that one flat's living room may be at the same height as the neighbouring flat's bedroom. Surveyors may note concerns about sound insulation between dwellings.
If you are aware of any structural issues, past remedial work, or building regulations approvals relating to the split level design, have the documentation ready. A structural engineer's report confirming the property is sound can be a valuable document to share with prospective buyers and their lenders.
Conveyancing considerations
The conveyancing process for a split level property follows the same steps as any residential sale, but there are additional points that the buyer's solicitor is likely to raise during the enquiry stage.
Building regulations and planning
If the split level layout was created by a conversion or structural alteration (rather than being part of the original build), the buyer's solicitor will want evidence that the work was carried out with the necessary consents. This includes:
- Building regulations completion certificate for any structural work that altered floor levels
- Planning permission if the external appearance or use of the building was changed
- A certificate of lawful development if the work was carried out more than four years ago without formal approval
- Indemnity insurance if no approval can be obtained retrospectively — your solicitor can arrange this
The TA6 form
When completing the TA6 Property Information Form, pay particular attention to:
- Section 1 (Boundaries): If the split level design means your property extends to different levels relative to neighbouring properties, clarify the boundary position clearly.
- Section 5 (Alterations and planning): Disclose any structural work that created or modified the split level layout, and provide copies of building regulations and planning approvals.
- Section 7 (Damp and structural issues): Disclose any known issues with damp at level junctions or structural movement.
Property searches
The standard property searches ordered by the buyer's solicitor (local authority, environmental, water and drainage) apply to split level properties in the same way as any other residential sale. The local authority search will reveal any building regulations applications and planning history, which is particularly relevant if the split level layout was created by a conversion.
Marketing a split level property
Marketing is where split level property sales are won or lost. The layout is unusual, and buyers need to understand the flow of the space before they commit to viewing. Poor marketing that fails to convey the layout will deter buyers; effective marketing that showcases the design attracts the right audience.
- Commission a detailed floor plan. A clear, labelled floor plan is essential for any split level property. It should show each half-level, the position and number of steps between them, and room dimensions. Without a floor plan, buyers struggle to understand the layout from photographs alone.
- Use wide-angle photography at level changes. Photograph from the top of each internal staircase looking down into the next space, and from the bottom looking up. These transition shots help buyers visualise the flow between levels.
- Consider a 3D virtual tour. Virtual tours are particularly effective for split level properties because they allow buyers to navigate through the space and understand the level changes before visiting in person. This can filter out buyers for whom the layout is unsuitable and attract those who appreciate it.
- Emphasise the spatial benefits. In the property description, highlight the natural zoning that split levels provide — separate living and sleeping areas, quiet home office spaces, and the feeling of a larger property without additional square footage.
- Acknowledge the layout honestly. Trying to downplay or hide the split level nature of the property will backfire when buyers arrive for viewings. Be upfront about the internal steps and present them as a design feature rather than a compromise.
- Target the right audience. Ask your estate agent to market the property through channels that reach buyers interested in architectural character, period design, or distinctive homes. Standard family-buyer-focused marketing may not reach the audience most likely to appreciate a split level layout.
Preparing a split level property for sale
Presentation is important for every property sale, but split level homes benefit from particular attention to how each level is staged and how the transitions between levels feel.
- Declutter the staircases. Internal steps in split level properties are often narrow or open-plan. Keeping them clear of clutter makes them feel safer and more spacious during viewings.
- Ensure good lighting at level changes. Dark staircases between levels can feel oppressive. Install adequate lighting at each transition point so buyers can see clearly as they move between half-floors.
- Check handrails and balustrades. Loose or missing handrails are a safety concern and will be noted by surveyors. Ensure all staircases have secure, well-maintained handrails.
- Stage each level with a clear purpose. The strength of a split level layout is the natural zoning it provides. Stage each half-floor to demonstrate its intended use — living room, dining area, home office, sleeping zone — so buyers can see how the space works in practice.
- Address any damp or structural concerns. If there are signs of damp at level junctions or cracking at the points where different sections of the building meet, have these investigated and remedied before listing. A clean survey report is far more valuable than hoping the buyer's surveyor will not notice.
Split level flats: additional considerations
If your split level property is a flat rather than a house, there are additional factors to consider that combine the challenges of split level living with the requirements of flat sales.
- Leasehold requirements. Most split level flats are leasehold. You will need a management pack, the TA7 Leasehold Information Form, and all the standard leasehold documentation. The split level layout does not change the leasehold conveyancing process, but it may generate additional buyer enquiries about sound insulation between units and structural maintenance responsibilities.
- Sound insulation between flats. In split level blocks, the staggered floor levels mean that your floor may be at the same height as a neighbouring flat's wall. Sound transmission can be a concern, and the buyer's surveyor may flag this. If sound insulation work has been carried out, have the documentation ready.
- Service charge allocation. In some split level blocks, service charges are allocated by floor area. Because split level flats can have unusual configurations, the allocation may not seem proportionate to the buyer. Ensure the service charge breakdown in the management pack is clear and consistent.
- EPC considerations. The Energy Performance Certificate for a split level flat may be affected by the layout, as multiple level changes can complicate the thermal efficiency assessment. Ensure your EPC is current before marketing.
Comparing split level to other property types
Understanding how a split level property compares to other types helps you set realistic expectations about buyer interest and pricing:
| Feature | Split level | Standard house/flat | Maisonette |
|---|---|---|---|
| Internal steps | Multiple short flights between half-levels | One staircase between full storeys (or none) | One staircase between two full floors |
| Accessibility | Poor — difficult to adapt | Good (single level) to moderate (two storey) | Moderate — standard staircase can take stairlift |
| Natural zoning | Excellent — distinct areas on each half-level | Moderate — relies on room layout | Good — separate floors |
| Buyer pool | Narrower — excludes some family and older buyers | Broadest appeal | Broad — similar to houses |
| Mortgage availability | Generally unaffected by layout alone | Standard | Standard |
| Survey focus | Structural junctions, differential settlement, fire escape | Standard checks | Standard checks plus shared structure |
Seller's checklist for a split level property
Use this checklist alongside the standard selling process to cover the issues specific to split level homes:
- Instruct an estate agent with experience of split level or architecturally distinctive properties in your area
- Commission a detailed floor plan that clearly shows each half-level and the step positions
- Gather building regulations approvals and planning permission for any structural work that created or modified the split levels
- Check for signs of differential settlement or cracking at level junctions and arrange remedial work if needed
- Address any damp at level change points, particularly where floor meets wall at different heights
- Ensure all internal staircases have secure handrails and adequate lighting
- Complete the TA6 form honestly, disclosing any structural alterations and providing supporting documentation
- Consider a 3D virtual tour or video walkthrough to help buyers understand the layout before visiting
- Price realistically based on comparable sales, accounting for the narrower buyer pool
- Stage each half-level with a clear function to demonstrate how the space works in practice

Frequently asked questions
What counts as a split level property?
A split level property is one where the floor levels are staggered rather than aligned on a single plane. Instead of each storey being at the same height throughout, rooms sit at different levels connected by short flights of steps. This can mean a living room that is half a storey above the kitchen, or a bedroom that is reached by going up or down a few steps from the hallway. Split level designs are found in purpose-built houses and flats, conversions of older buildings, and properties built on sloping sites where the architect worked with the natural gradient of the land.
Are split level properties harder to sell?
Split level properties can take longer to sell than standard single-level equivalents because the layout does not suit every buyer. Families with young children, older buyers, and anyone with mobility concerns may rule out a split level home due to the internal steps. However, split level properties appeal strongly to buyers who value architectural character, distinct living zones, and the sense of space that staggered levels create. Pricing accurately and marketing to the right audience are the keys to a successful sale.
Will a mortgage lender lend on a split level property?
Most mainstream mortgage lenders will lend on a split level property without specific restrictions related to the layout. The lender’s surveyor will assess the property on its overall condition, value, and marketability rather than rejecting it solely because it is split level. However, if the split level layout is the result of an unconventional conversion or the property has unusual construction features alongside the split levels, some lenders may classify it as non-standard and apply additional conditions. The buyer’s mortgage broker should check lender criteria before applying.
How does a split level layout affect property value?
The effect on value depends on the local market and the quality of the design. A well-designed split level property in an area where buyers appreciate architectural character can achieve the same or higher prices per square metre as a standard layout. In areas dominated by family buyers who prioritise practicality, a split level may attract a modest discount of 5% to 10% because of the reduced buyer pool. The most important factor is whether the split levels create genuinely useful living spaces or feel awkward and impractical. A good estate agent with local knowledge can advise on how the market in your area responds to split level homes.
Do I need to disclose the split level layout on the TA6?
The TA6 Property Information Form does not have a specific question about split level layouts. However, if the split levels were created through a conversion or structural alteration, you should disclose this under the alterations and planning section of the TA6. If building regulations approval or planning permission was required for the work, provide copies of the approval certificates. If the alteration was carried out without the necessary consents, you should disclose this and discuss with your solicitor whether indemnity insurance is appropriate.
What survey issues come up with split level properties?
Surveyors pay particular attention to the structural integrity of split level properties, especially where internal floor levels have been altered from the original design. Common findings include stepped cracks at the junctions where different floor levels meet, evidence of differential settlement where one section of the building has moved differently from another, and signs of damp where changes in level create complex junctions between walls and floors. If the split level was created by a conversion, the surveyor will also check for evidence of building regulations compliance and adequate structural support.
Can I convert a split level property to a single level?
Converting a split level property to a single level is sometimes possible but usually involves significant structural work and cost. Raising or lowering floor levels requires underpinning or new structural supports, and the work must comply with building regulations. Planning permission may also be required if the external appearance is affected. In most cases, the cost of conversion far exceeds any increase in property value. It is usually more practical to sell the property as a split level and market it to buyers who appreciate the layout rather than spending heavily to change it.
Are split level flats affected by different lending criteria to split level houses?
Split level flats and split level houses are assessed on broadly the same basis by mortgage lenders. The lender’s surveyor considers the property’s condition, value, and marketability. For split level flats that are leasehold, the standard leasehold requirements also apply — lease length, ground rent, service charges, and management pack documentation. The split level layout itself does not usually trigger additional lending restrictions for either flats or houses, provided the property is of standard construction and in reasonable condition.
How should I photograph a split level property for marketing?
Photographing a split level property effectively is important because the layout can be difficult for buyers to understand from standard photographs alone. Use wide-angle shots from the top of internal steps looking down (and vice versa) to show how the levels connect. Include a floor plan that clearly labels each half-level and shows the step positions. Consider commissioning a 3D virtual tour, which allows buyers to navigate between levels and understand the flow of the space before visiting. Good photography that conveys the spatial quality of the design can make the difference between attracting interest and putting buyers off.
Do split level properties take longer to sell?
Split level properties can take slightly longer to sell than standard layouts because the buyer pool is smaller. Some buyers actively seek split level homes for their character and spatial separation, but others — particularly those with accessibility needs — will not consider them. On average, you should allow an additional two to four weeks of marketing time compared with a conventional property of similar size and price in the same area. Accurate pricing from the outset is the most effective way to avoid an extended time on the market.
