Loft Conversions – Main Types & Designs

Below are examples of the main types of loft conversions and extensions we currently undertake.

We cover the Home Counties and London areas including Kent, Surrey, South London, Wimbledon, Bromley, Twickenham, Richmond and many, many more.


Dormer loft conversions are the most common type requested by residents. With a dormer conversion we extend the existing roof vertically to create extra floor space and headroom.

To achieve this, it is important that at least half of the current floor space has a ceiling height of at least two metres or higher. Dormers usually do not require planning permission.


A Velux, or roof light loft conversion is the most simple and economical type available. With a Velux, the roof remains unchanged, other than the installation of attractive flush Velux windows to give plenty of natural light.

Typically, a Velux attic conversion does not need planning permission as the roof structure remains unchanged. This is the perfect solution if you want minimal outlay and disruption.

Single Flat Roof Dormer

By far the popular loft conversion usually on terraced semi and detached houses can create a bedroom and en-suite up to 50m2. Very cost effective loft conversions as a simple dormers.

Two rear windows one for loft one for en-suite.

Suitable for all types of houses. Planning permission usually not required as this is a “ Permitted Development.”

Mrs Wilkes (Teddington, TW11)

We are a retired couple from Warwick and wanted to move closer to our daughter. Touchstone lofts consultant came out and explained in great detail what could be done and the budget required. The works started quickly and the teams were friendly, professional and quality is very high. Overall, we are delighted and would highly recommend Touchstone Lofts.

Dr Young
 (Chiswick, W4)

We wanted a design that would complement our existing home and extension, we were very particular about who we worked with and Touchtone lofts fitted the bill. Touchstone Lofts impressed us from the start and we were not disappointed by the whole smooth and efficient build and final product, we would highly recommend them for a quality and service.

Dr Morton (Richmond TW10)

Touchstone took on the planning department and managed to get two Pitched roof dormers for our property which was a first for this conservation area. The quality of the work was excellent, we have had no issues with the quality of the works.
