Can I extend my W4 terrace under permitted development?

“Many rear and side-return extensions on Chiswick houses fall within permitted development, subject to depth and height limits.

How much does a loft conversion cost in Chiswick?

“A rear dormer on a Chiswick terrace typically costs £50,000-£90,000. High-specification conversions with en-suites and bespoke joinery typically run £90,000-£160,000, and full mansards £130,000-£210,000. Conservation-area constraints in Bedford Park or Grove Park add heritage and design costs.”
