Why choose us
Why Choose Us for Your Wimbledon Loft Conversion?
A successful loft conversion needs more than extra floor space. It needs the right design, staircase position, head height, structure and finish.

Whether your property is close to Wimbledon Village, Wimbledon Common, South Wimbledon, Wimbledon Park or Raynes Park, we plan the conversion around your roof type, family needs and approval route.
Our approach is practical and design-led: we look at head height, roof structure, staircase access, insulation, fire safety, natural light and how the new room will feel once complete.

- Support with permitted development, planning permission and Building Regulations
- Loft layouts designed for bedrooms, offices, en-suites and storage

Loft conversion types
Popular Types of Loft Conversions in Wimbledon
Different roof shapes need different conversion solutions. We help you choose the option that creates the right space while respecting the property and planning position.
Mansard Loft Conversions
Mansard loft extensions can create a larger, more premium top-floor space, often suited to period homes where a bigger transformation is required.
Hip-to-Gable Loft Conversions
Ideal for many semi-detached and end-of-terrace homes, this approach extends the sloping roof side to create more internal loft space.
Rooflight / Velux Conversions
A rooflight loft conversion can be a simpler way to upgrade attic space where there is already enough head height and minimal roof alteration is needed.
L-Shaped Loft Conversions
Popular on some Victorian and Edwardian properties, an L-shaped loft can create generous rooms across the main roof and rear outrigger.
Attic Storage & Eaves Design
Built-in eaves cupboards, wardrobes and concealed storage help make the new loft space practical, tidy and valuable every day.

Our process
Our Wimbledon Loft Conversion Process
We keep the route clear from early feasibility through to the finished loft space, so you understand the design, approvals, build stages and practical details before work begins.
Survey and feasibility
We assess head height, roof structure, stairs, access, property type and your goals for the new loft space.
Design and specification
We help shape the layout, dormer or mansard approach, rooflights, storage, en-suite position and finishes.
Planning and Building Regulations
We advise on permitted development or planning permission and coordinate Building Regulations requirements.
Build and project management
The work is managed through structure, roof works, stairs, insulation, services, plastering and finishing.
Final clean and handover
We check details, complete final snagging and hand over your new Wimbledon loft space ready to use.
Planning & permissions
Planning Permission & Permitted Development in Wimbledon
Many loft conversions can fall under permitted development, but this depends on the property, roof alterations, volume limits, materials and whether restrictions apply. Wimbledon homes in conservation-sensitive areas or affected by previous alterations may need full planning permission.
Building Regulations approval is still required for loft conversions, covering structure, fire safety, stairs, insulation, ventilation and electrical work.
- We check whether your loft conversion may qualify under permitted development.
- We advise when Merton Council planning permission may be required.
- We consider conservation areas, Article 4 restrictions and period-property detailing.
- We support Building Regulations coordination for structure, stairs and safety.
