Types of House Extensions We Offer

When it comes to house extensions in London, we are the trusted extension contractors offering a wide range of home extensions, including:

Ground Floor Extension

Whether your home feels cramped or your family is growing, the ground floor extension is the best pick, providing endless possibilities with a new kitchen, bedroom, living room, or conservatory. 

Single Storey Extension

We construct this extension when your house has already had its ground floor extended to its rear or side. You can unlock countless possibilities by opting for this extension, which can be used as a:

  • Living room
  • Bedroom
  • Kitchen
  • Playroom
  • Home office

Double Storey Extension

We can add a double-storey extension to any part of your house. Constructed only on detached or semi-detached houses with a side plot or garden, they are relatively complex but ensure the maximum use of available space.

Rear Extension

A rear home extension is added on the rear side of your house, keeping the front view the same as before. It is among the most common types and is a popular choice for Edwardian house extensions, transforming the outdoor space while reserving the traditional design of Edwardian homes.

Over-structure Extension

This extension is built on the existing structures, usually a garage or first floor, adding an extra bedroom or bathroom to your home. It is often used to maximise the value of your home.

Wraparound Extension

It’s a hybrid extension, a combination of rear and side return extensions forming an L shape. You can consider this if you are looking for a suitable Victorian house extension option. It also works great for modern homes with enough space.

Side Return Extension

The pathway running alongside your home can be transformed into a side return extension, improving the overall value of your space. The main benefits of this extension are:

  • Easy to build.
  • No extensive groundwork needed.
  • Boosts your home’s resale value.

Modular House Extension

A modular home extension is prefabricated and custom-made to meet your requirements, with no mess or fuss at your site. It is a time-saving option and is best for both commercial and residential buildings. 

Glass Room Extension

A glass room extension is a modern choice for homes, improving your space’s overall functionality and aesthetics. It is a widely used contemporary house extension option as it perfectly matches modern home designs. Glass room extensions are bespoke and offer countless possibilities.
