Our Specialist Loft Conversion Services in Westminster

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

Is Planning Permission always needed for a loft conversion in Westminster?
Often, yes. While some minor Dormer conversions may fall under Permitted Development (PD), the majority of properties in Westminster's Conservation Areas (which cover much of the borough) require full Planning Permission from the CWC. Building Control is always mandatory.
A full loft conversion in Westminster typically takes between 12 to 16 weeks on-site, following several months of crucial pre-construction work (planning, Party Wall Agreements, and structural design).
Yes. If your conversion involves working on the shared wall (Party Wall) with your neighbour—which is standard for terraced or semi-detached homes—a Party Wall Agreement is legally required. We manage this process fully.
Absolutely. Adding a new bedroom and bathroom through a high-quality conversion is one of the best ways to boost the value of a Westminster property, often yielding a significant ROI due to the premium value of local square footage.
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.
