House Extensions in London

High quality craftsmanship at competitive rates

House extensions can add around 25% to the value of your property and basement or loft conversion will typically boost the property value by 10% to 15%.

Providing costing for an `average` extension can be tricky since-there really is no average!

However, factors such as ground condition, access to the site, location, and proximity of services make a huge difference to the building budget. Therefore, in providing indicative costs, we will have always assumed that all these issues can be reasonably dealt with.

Kitchen Extensions in London

Kitchen extension can add between 12% to 18% to the value of your home, and it can also become multi-functional room in the house.

Ensure you make the most of the layout of your kitchen. Ideally, it may overlook the garden if itis combined with an open plan dining area and possibly a living area.

Our single storey extension should cost between £20,000 to £ 50,000 to build depending on the location, size, specification and complexity of the build.
