A lot of what people think they know about loft conversions in London is a few years out of date, or wasn’t quite right to begin with. Costs, planning rules, and what’s actually possible under a low roofline. Most of it gets exaggerated somewhere along the way, usually by someone who’s never actually done one.London lofts aren’t all the same problem to solve. Victorian terraces come with steep original roof pitches. Ex-council flats often have a shared structure to work around. Newer builds sometimes have less usable roof space than the outside suggests. Each one changes what’s actually possible before a single beam gets touched, which is exactly why we look properly before quoting.
