Buying a Three Bedroom Maisonette in SE13: Key Checks

Reviewed 6 September 2026

A three bedroom maisonette can offer some of the separation associated with a house while remaining part of a larger building. That combination is worth exploring, but the floor plan does not tell you everything about ownership, access or repair responsibilities.

For a buyer searching in SE13, the useful comparison is not simply three bedrooms against three bedrooms. It is how the accommodation works, what comes with it and what obligations continue beyond your own front door.

What does maisonette mean for this property?

Estate agency descriptions use the term maisonette for accommodation with a degree of independence, often including a separate entrance or rooms over more than one level. The precise arrangement needs to be established from the actual property.

Look at where the entrance is, which staircase belongs to the home and whether any route is shared. A photograph of a front door does not establish ownership of the steps, passage or land around it.

Treat the floor plan and title as complementary documents. One explains the arrangement; the other establishes the legal extent and rights.

Assess the benefit of separate levels

Accommodation over two floors can help separate living and sleeping. It may also create more stairs, landing space and routes through the home.

Consider how the arrangement would work when someone is working, another person is cooking and a third wants quiet. Check where the bathroom and any additional toilet are located. A second facility can be useful, but it should be accurately distinguished from a second bathroom.

Our article on why split level living can work well explores these everyday advantages and compromises in more detail.

Look beyond the bedroom count

A third bedroom has value only if it can serve the purpose you need. Check dimensions, ceiling height, storage and the route to the room.

Decide whether a smaller room will be a permanent bedroom, a study or occasional guest accommodation. A property may meet the bedroom count while still lacking the storage or shared living space your household needs.

Compare the reception room and kitchen with the homes you are considering. A generous sleeping area does not compensate for an arrangement that makes everyday meals or working at home difficult.

Establish the garden and access rights

Some maisonettes have direct garden access. Others use a side route or share outside space. The word garden should therefore prompt a question, not an assumption.

Ask whether the area is owned with the property, held under the lease or available through a right of use. Check who can cross it, who maintains boundaries and whether any outbuilding is included.

If the route passes over another part of the building or plot, have the conveyancer explain the right of access. Informal arrangements between friendly neighbours are not a substitute for the rights a buyer needs.

Understand responsibility for the whole building

Even with an independent entrance, a maisonette may share the roof, foundations, external walls or services with another home. How are repairs decided, organised and paid for?

The Leasehold Advisory Service explains service charges and the importance of the lease terms. In a smaller conversion, an absence of a large annual charge should not be mistaken for an absence of responsibility.

Ask what happens if urgent work is needed or the other owner disagrees. The legal documents and management arrangements matter more than a reassuring statement that everyone has always got along.

Investigate alterations and condition separately

An upper floor conversion, changed staircase or new bathroom may require more than a visual check. Your conveyancer should investigate the relevant documentation and consents, while a surveyor assesses the physical condition within the agreed scope.

A mortgage valuation is not a substitute for the buyer's own condition assessment. RICS provides guidance on selecting a home survey for different properties and circumstances.

Do not assume that attractive period details mean the building has been maintained, or that modern finishes prove alterations were properly authorised.

How should you compare the price with a house?

Start with properties buyers could genuinely choose instead. Consider size, layout, garden rights, condition and ongoing costs, not just distance from the address.

A freehold house and a leasehold maisonette may offer different responsibilities and restrictions. That does not make either automatically better, but it does mean that the same bedroom count is an incomplete basis for comparison.
