Question: I own two flats that are next door to each other in the same block.

The front doors face each other and I would like to put up a partition with a door across the corridor, which would then provide a lobby and a common entrance to the two flats. Would there be any problems in doing this?

Answer: As your flats are in a block, I assume that they are leasehold and that the corridor area is part of the common parts, which will usually belong to the freeholder or management company.

You will need to check the leases, which will confirm who owns which parts of the block. You will need the consent of the freeholder and/or the management company, whose decision will depend on whether any other flat owners in the block need access to any part of the corridor you wish to take over.

If the corridor is only used by your two flats, permission would probably be forthcoming provided the area is reinstated to its original condition at the end of the leases, or when the flats come into separate ownership. You should expect to make a one-off payment and pay the freeholder’s legal fees.

Although studding walls and a door would not usually require building regulations approval, you should check the situation with the building inspector.
