Victorian terraces and conversions
Streets of Victorian terraces in Battersea, Balham, Tooting and Earlsfield are often split into upper and lower flats. The lower flat usually has the garden, and a flap in the back door or a glazed garden door works well with the freeholder's consent. Whole houses typically have a rear extension with a back or side door.
Glass doors
Many extended homes have bi-fold or French doors onto the garden. A flap can go into a replacement sealed glass unit made with an opening, which avoids cutting a door frame.

Questions from homeowners in Wandsworth
I own a leasehold flat. What do I need to check?
Your lease, which usually needs the freeholder's written consent for changes to doors, windows or walls. A flat's front door in a shared building is a fire door and can't take a flap.
Can a flap go in a bi-fold door?
Often, by replacing one glass panel with a sealed unit made with an opening. We'll check the door system first.
