Hammersmith is Victorian terraces in Brackenbury Village and around Ravenscourt Park, mansion flats along the river, and Edwardian houses towards Stamford Brook. Side-return kitchen extensions on the Brackenbury and Ravenscourt terraces are the most common Hammersmith project, often with a lower-ground dig-out to add a family room.
Hammersmith's conservation areas include Ravenscourt and Starch Green, Bradmore (which takes in part of Brackenbury Road), Brook Green and Hammersmith Odeon; Hammersmith and Fulham Council applies a strict basement policy. Most Hammersmith extensions we price fall between £2,500 and £4,000 per m², so a 25–30 m² kitchen extension is roughly £75,000–£120,000 fitted out; our house extension cost guide breaks the numbers down. We check permitted development rights at the first visit and deal with Hammersmith and Fulham Council in-house.

Loft conversions in Hammersmith
Hammersmith's Victorian roofs suit L-shaped rear dormers; in a conservation area any dormer needs planning permission, and the council resists front roof extensions and ridge changes that harm a terrace.
Expect £45,000–£75,000 for a dormer loft with a bedroom and en-suite, £60,000–£100,000+ for a mansard and from £25,000 for a Velux conversion; the loft conversion cost guide has the breakdown. For a Hammersmith loft we measure head height, roof structure and the stair landing first, and the quote includes structural calculations and Building Regulations approval.
Renovations and refurbishment in Hammersmith
Hammersmith refurbishments are full renovations of Victorian terraces and mansion flats, with new kitchens, bathrooms and restored period features. Typical Hammersmith refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. See our renovation cost guide for realistic budgets. Hammersmith projects are run by a single project manager under a JCT contract, with a written specification and a 10-year workmanship warranty.

Common questions about building in Hammersmith
Do I need planning permission for an extension in Hammersmith?
A house (not a flat or maisonette) keeps national permitted development rights for a single-storey rear extension of 3m attached or 4m detached, or up to 6m or 8m through prior approval, and most rear dormers within 40 or 50 cubic metres. Hammersmith and Fulham Council's conservation areas here include Ravenscourt and Starch Green, Bradmore, Brook Green, Hammersmith Grove, Hammersmith Odeon and The Mall, where side, two-storey rear, cladding and roof changes need permission. Article 4 directions go further: on most Bradmore terraces any rear structure needs permission, as do rear extensions on parts of Ravenscourt Road. Every basement needs permission borough-wide.
What does Hammersmith and Fulham Council expect for basements in Hammersmith?
A borough-wide Article 4 direction from April 2018 means any basement excavation needs planning permission. Local Plan Policy DC11 limits a new or extended basement to one storey, except on large sites, and it must not reach under the garden more than 50% of the host building's depth or 50% of the garden depth. It must be set back from neighbouring boundaries, keep at least 1m of soil over any part under a garden, and come with a Construction Method Statement from a qualified structural or civil engineer.
What does an L-shaped dormer loft conversion cost in Hammersmith?
Our London figures, including VAT, are £55,000–£85,000 for an L-shaped dormer and £45,000–£75,000 for a rear dormer. The L-shape suits Hammersmith's Victorian terraces with a back addition, giving room for a bedroom and en-suite. In a conservation area, or at an Article 4 address, the dormer needs planning permission, which adds design time. Our dormer loft conversion cost guide explains the breakdown.
