Question 1

What does it cost to add a rear ground-floor extension to a Charlton (SE7) Victorian terrace?

Accepted Answer

Expect to spend roughly £34,000 to £58,000 on a ground-floor rear extension to a SE7 Victorian terrace — foundations, structural steels, masonry walls, flat or pitched roof with glazed lantern or skylight, bi-fold or sliding doors, plastering, and electrics. The terraces around Charlton Village often have a small projecting rear return that can be enclosed as part of the same project, adding meaningful floor area to the resulting kitchen-diner.

Question 2

Does the Grade I listing of Charlton House create planning restrictions for homeowners nearby in SE7?

Accepted Answer

Charlton House's Grade I designation protects the building itself and its immediate curtilage, but it does not impose blanket restrictions on the residential streets around it. Most SE7 homeowners fall under standard Royal Borough of Greenwich permitted development rules, meaning rear extensions and loft conversions can proceed without a full planning application. The exceptions apply to properties that sit within a defined heritage setting boundary or within an active conservation area — PrimeCraft checks your exact position at the survey before pricing is prepared, so there are no consent surprises mid-project.

Question 3

What does a gable-end loft conversion with rear dormer cost on an SE7 interwar semi?

Accepted Answer

Gable-end conversions with a rear dormer on the interwar semis along the Woolwich Road corridor typically price between £45,000 and £66,000 for the structural package — gable rebuild, dormer framing, steelwork, roofing, insulation, boarding, staircase, and plastered shell. Fitting an en-suite bathroom brings that total to approximately £54,000 to £80,000 depending on sanitaryware and finish. Party Wall Act obligations toward the adjoining property are handled from the outset and factored into the programme schedule.
