BUILDING IN HAMMERSMITH
Rear kitchen extensions with full-height glazing, lofts under new dormers — Hammersmith's Victorian terraces take both, and our completed W6 extension shows the standard we hold. One team from design to building control, fixed itemised price throughout.
Dormer and hip-to-gable loft conversions add bedrooms to Hammersmith's terraces and semis — a cost-effective way to upsize in place.
Local advantage
Why homeowners in Hammersmith choose Dali Pro Services for loft conversions
01 · PLANNING HANDLED
Volume limits, dormers and conservation streets — checked before you commit.
Most lofts in Hammersmith convert under permitted development if the added volume stays within the limits; where the route changes, the application goes to Hammersmith & Fulham Council. The classic terrace route here is a rear dormer or an L-shape over the outrigger — usually within permitted-development volume limits. We measure head height on the first visit, confirm feasibility honestly and handle whichever consent applies.
02 · ONE TEAM
Staircase, steels and headroom — decided on the drawings, not on site.
A loft stands or falls on three decisions: where the staircase lands, how the steels carry the new floor, and where the full-height space goes. Because design and build are one in-house team, those calls are made once, on the drawings — never improvised mid-build.
03 · TRANSPARENT PRICING
£60k–£140k typical — itemised and fixed.
Your quotation is broken down line by line — structure, dormer, glazing, bathroom, finishes — and fixed against the agreed drawings. You pay in stages, only after each stage is signed off; variations only happen when scope genuinely changes, through written authorisation.

How tall must my loft be to convert?
You need at least 2.2m of head height in the existing loft. We measure on the first visit and confirm what conversion fits.

Most of the work happens upstairs, with rooflight access for materials. You stay in your home throughout.
