Loft Conversions

Loft Conversions
in Banstead, Reigate and the Surrounding Areas

Our range of loft conversions offers the perfect solution to any homeowner looking to expand floorspace and get the most from a property. The options for internal layouts are vast, from additional bedrooms to home offices, playrooms to studios. Specialists in various property refurbishments and renovations, our new home builders at Joshua Lewis Carpentry and Construction Ltd design and construct several layouts to suit homes in Banstead, Reigate and the surrounding areas.

Make Space Without Moving

The best conversion for your needs will depend on the shape and size of the existing attic, the desired outcome, your budget, and whether or not planning permission is required. It’s also important to consider the following points:


The minimum ceiling height for an approved conversion is 2.2m (7.2ft). This is to ensure the area complies with health and safety regulations.

Ease of Access

Natural Light

You don’t want to rely on artificial light to illuminate the new space all the time, so make sure your preferred interior allows for plenty of natural light.

Planning Permission

Some renovations, such as mansard loft conversions, will almost certainly require planning permission as they dramatically alter the existing roof’s structure. We can advise you on this.

Which Style Will Suit You?

If you’re considering making the change and adapting that unused attic space, call us today at Joshua Lewis Carpentry and Construction Ltd. Our new home builders design and construct the following conversions for our growing number of clients:

  • Rooflight Loft Conversions

  • Dormer Loft Conversions

  • Hip-to-Gable Loft Conversions

  • Mansard Loft Conversions

Rooflight Conversions

We can install Velux windows for properties with existing high-pitched roofs to create brighter interiors. This is the most affordable conversion with minimal work required internally and externally. 

Dormer Loft Conversions

By building single or multiple box-shaped structures outwards from the roof’s pitch, we can alter one side of the interior to house additional head and floor space. With vertical walls and flush windows, the new layout is perfect for a bedroom or home office. 

Hip-to-Gable Loft Conversions

Our team can create a significant amount of new space by changing the roof’s hip into a vertical wall at the gable end of your Banstead or Reigate property. Suited to both detached and semi-detached homes, the extra room is perfect for bathrooms and walk-in wardrobes. 

Mansard Conversions

These are a complete game-changer as they require major reworking of the existing roof. By raising the roof completely and inserting supporting walls, we can create a whole new storey. Mansards can accommodate an entirely new living space with endless possibilities.
