Question 1

What does dormer loft conversion work cost on the SW19 Victorian terrace stock?

Accepted Answer

Adding a dormer to open up the roof space on a SW19 Victorian terrace — structural steels, dormer frame, roofing, staircase, and a fitted bedroom with en-suite bathroom — generally falls between £50,000 and £76,000. Head height, roof pitch, and finish level are the main variables. Properties along streets closest to the River Wandle corridor sometimes need additional structural assessment where historic mill-related ground conditions are present. We hand over a fully itemised quote on the day of the site visit.

Question 2

Do rear extensions on Colliers Wood terraces need a planning application (SW19)?

Accepted Answer

Single-storey rear extensions on terraced properties in SW19 typically fall within permitted development: up to 3 metres depth without notification, or up to 6 metres under the neighbour-consultation scheme. The streets around the Northern line station carry no Article 4 direction withdrawing those rights, and there is no conservation area covering the main residential grid. We confirm each property's planning position at our initial site visit and flag any exceptions — such as a corner plot or an HMO — before any design cost is incurred.

Question 3

Which renovation projects are in highest demand across SW19?

Accepted Answer

Ground-floor kitchen extensions — opened up into an open-plan layout with a full new kitchen — are consistently the project type we price most often across the Colliers Wood area. Dormer loft conversions come next, adding a bedroom and en-suite without reducing garden space. Full bathroom refits and boiler replacement through our Gas Safe registered partner are routinely folded into the same contract once the structure is already open. The River Wandle Trail corridor nearby makes garden rooms and outdoor landscaping a growing part of renovation scopes in SW19.
