Combining adjoining flats is a clever way to create a larger home in Marylebone. We design structural openings and rear or side infills where possible. Marylebone extensions like this respect the building’s original charm and layout.
In Mayfair, some homes can add a roof terrace or modest green roof, subject to strict planning. We handle surveys and permissions with Westminster Council. Your Mayfair rooftop can become a discreet, private outdoor retreat.
Soho’s unique live-work vibe makes extending above shops attractive for owners. We explore adding upper floors or rear extensions for flats. A Soho mixed-use extension must meet heritage and commercial rules too.
Yes, frameless glass boxes brighten enclosed Marylebone courtyards, adding modern dining areas or studies. They respect surrounding brickwork yet feel strikingly modern. We design Marylebone extensions that mix old and new tastefully.
Soho extensions need clever acoustic insulation due to nightlife and shared walls. We use soundproofing materials and sealed glazing. This keeps your Soho extension peaceful inside, even in lively streets.
Adding a small internal lift is sometimes possible in taller Marylebone townhouses when extending. It’s ideal for accessibility or future-proofing. We handle Marylebone design so new features blend with classic staircases.
Mayfair luxury homes sometimes add basement or rear extensions for staff quarters. Separate entrances and compact living design are key. We plan Mayfair layouts for privacy while fitting within tight footprints.
Many top-floor Soho attics can be converted into bright workspaces with roof lights and dormers. It’s perfect for creatives working from home. We make sure your Soho attic extension stays compliant and stylish.
