Touchstone home extensions team can extend your domestic home in many ways.

Ground floor house extensions: ground floor extensions can be built to the rear and sides of your property. We can do all the ground works, brickwork, windows, roofing with flat roof lights including lanterns. First floor home extensions can also be built.

Most original layouts in UK homes are not suited to current lifestyles. The kitchen is too small and the two receptions are not big enough separately. The front reception is rarely used and dining rooms are not used daily. The lifestyle for a modern growing family has a different home layout requirement. Kitchens are now open plan connected to the living space and lounges are much bigger. Access to gardens are bigger and can be opened up using wide patio doors from two metres up to six metres wide allowing the outdoors in. A house extension at the rear of some 6 metres will accommodate this new layout with ease.

Touchstone extensions can show you how a new home extension can improve your lifestyle and add significant value to your home.

Building Regulations and Structural Engineering

Preparing drawings with full building regulations are essential for any project. Touchstone London Builders work closely with building regulations regulators to ensure we comply with all legal regulations. We comply with “Building regulations 2000 plus amendments” There are various aspects to building regulations which include:-

Structural engineering

All our projects involve a structural engineer who works throughout the project alongside the project manager. Using an architect and a set of structural plans is not ideal as the structural engineer and architect are not at hand to provide help should issue arise or changes are required.


With rising energy costs, sustainability is essential in all projects and these are an integral part of building regulations. Using insulation that is affordable, does not detract from the design of the works and exceeds legal “U” values is an important consideration in all our projects.

Fire protection

All our projects include a sensible fire compliance system that is affordable and not restrictive to the project design.


Adequate ventilation will ensure there is no condensation resulting in an unhealthy environment. Condensation is caused by poor building works and inadequate ventilation where required.

Electrical certification

Our NICEIC qualified electricians will provide a certificate to the building regulations department to ensure all application have been correctly fitted.
