Building in
Swiss Cottage.
NW3 around Swiss Cottage is substantial Victorian and Edwardian villas, many converted into flats, plus 1930s and post-war blocks. Space is usually won downwards into a basement or lower ground floor, or by reworking a cramped rear return.

Camden Council is the planning authority and conservation areas cover much of the area. Camden applies strict basement policy, so a basement impact assessment and structural design are normally required, and flats have no permitted development rights. We confirm what your address needs at survey.

The quality of service offered by Haim, our first contact, has been highly impressive. Every aspect of your service has been beyond reproach, courteous, polite and reliable. Great work done on our house!
You've been a great help. Your service is fantastic. I'm so glad I picked you guys.
Thanks for all your hard work on my flat. True professionalism. Highly recommended.
Thanks a million to you and your team, we are VERY impressed with the service and will spread the word whenever we can.
We had a rear extension and full kitchen fit-out. The programme was realistic, the site was kept tidy and the final bill matched the quote.
Loft conversion done in nine weeks. One site manager who answered the phone every time and sorted the building control sign-off for us.
Straightforward from the first survey. Clear itemised pricing, no surprise extras, and the plastering and decorating finish is excellent.
