In London no two properties are alike and neither are their owners. The same can be said of the Lofts in London, however having built hundreds, we at Clapham Construction Service, understand a thing or two about them. Though the finish may be different for every client the structure follows a few set designs. 

We have laid them out for you here to gain a better understanding

During the Home Consultation we will help you choose the right one for you and your home. 

Skylight Conversion
A skylight or "Velux" loft conversion is one of the simplest conversion types to build as the roof of the property is not altered which normal avoids planning permission. A great way to increase space at lower cost
Two Window Dormer
Often found on existing homes built 100 years ago and sometimes requested by the planning officers or by the client based on its style. This conversion provides a surprising amount of additional head room
Dormer Conversion
This is one of the most popular types of loft conversion. It provides a large amount of additional space up to 60 Cubic metres and really good head height. It also gives additional design potential such as Juliet balcony, floor to ceiling glass and roof lights.
L - Shape Dormer
This type of loft conversion is built by joining two dormer builds together, utilising the rear addition. This results in a significantly larger space than other builds. This conversion gives options for more bedrooms in the new build, a terrace on the rear addition and spare rooms, studies or bathrooms.
Mansard Conversion
A mansard loft conversion alters the structure of a sloping roof to an an angle of 72 degrees, given a unique shape as shown. Windows are fitted into the new roof almost like small window dormers.

Like Dormers the mansard conversion is usually erected to the rear of a property, but can be constructed as a front and rear Mansard (double mansard) if permitted.

This conversion provides a larger amount of space, effectively adding another floor to your home
L - Shape Mansard
As with the L-Shape Dormer, an L- Shape Mansard will add a larger amount of space with multiple design options by using the roof of the rear addition. Planning permission is required for this type of work, but we can submit approval for Juliet Balconies and a terrace to really make this conversion special
Hip to Gable
This is a simple conversion as shown in the image as all we have done is change the side sloping roof and raised this side in brick, which turns a low roof, with low head height into a workable space for any combination of conversion ... the most popular you will see next
Hip to Gable and Rear Dormer
As the title states, the side sloping roof has been raises, normally in brick, and allowed us the head height and structure to add a rear dormer.
