During 2023 Urban Space Ltd built a loft extension to my terraced house in East Dulwich, together with extensive renovations including a new bathroom, new windows, doors, floors, radiators, boiler, etc. Michael liaised with the party wall surveyors, devised imaginative solutions to various building problems and kept me informed of progress throughout the build. His team are first-rate and pay great attention to detail. The plumbing work was done with copper pipes, not push-fit fittings, the roof was finished neatly with lead work, and the carpentry and decoration was finished to a very high standard. I can strongly recommend Michael and his team.
It was a single key on a distinctive key ring, so probably not your grandad's - sorry!
