Our Specialist Loft Conversion Services in Chelsea

We design and construct all primary loft conversion types, each tailored to the specific structure and aesthetics of Kensington properties:

Dormer Conversions
Our most popular option, dormer conversions extend outward from your existing roof slope, creating maximum headroom and floor space.
Hip to Gable
Perfect for end-of-terrace or semi-detached homes, this conversion extends the sloped side roof to create a vertical wall.
Mansard Conversions
Offering maximum space, mansard conversions feature a flat roof with a back wall sloping at 72 degrees. Ideal for period properties.
L-Shaped Dormers
Combining a main roof dormer with a rear extension dormer, creating an L-shape that maximizes space in properties with extensions.

Common Questions

Frequently Asked Questions

Do I need Planning Permission in Chelsea?
Due to the high density of Conservation Areas in Chelsea (SW3/SW10), most significant loft alterations (especially Mansard and large Dormer conversions) will require full Planning Permission from the RBKC. We manage the entire application process, including listed building consent if required.
Once planning is secured (typically 8-12 weeks), the construction phase for a high-specification conversion usually takes 12–16 weeks, depending on complexity and whether significant structural work is involved.
While project scope varies, high-end conversions in Chelsea typically start from £70,000 to £85,000+ for a premium Dormer, reflecting the cost of superior materials, intricate structural work, and the bespoke interior finishes expected in SW3.
Yes. This is a crucial step for almost all terraced Chelsea homes. We liaise with experienced Party Wall Surveyors and manage the agreement process with your adjoining neighbours professionally and discreetly.
The cost of a loft conversion depends on factors such as size, design, materials, and structural requirements. On average, prices start from £25,000, but we provide a detailed quotation after an on-site assessment and design consultation.
