Side house extensions

London architect guide

Inspiration and ideas

Side return extensions to houses and garden flats are a great way to add space on the ground floor where the kitchen and utility areas were traditionally placed. At this early stage we encourage you to follow a three step process of thinking about the type of extension you want, considering some design aspects, and then looking for inspiration to cement your own ideas.

As part of this Side extensions London architect guide we have selected some projects to lend architectural inspiration and design ideas for your side return extension.

Side house extensions London architect guide – Design aspirations and key considerations

One of the most common challenges in a full side return extension is that it will often result in blocking the light coming in from the door/window that exists at the rear part of the elevation.

The most common way of solving this is by allowing for rooflights to the new side roof. The further back the rooflights are the better it is since natural light can reach deeper into the floor plan and help to define a new dining or kitchen area at the rear part of the house or flat.

Another good solution is to avoid building up to the rear door/window. This creates the opportunity for what we describe as an ‘external room’, a landscaped courtyard between the existing house and the new extension.

Remember it is always possible to open up the wall between the front and rear reception rooms and bring light from the front room into the middle room while at the same time creating long views across the ground floor.

Side house extensions London architect guide – Start here and design your side return extension

During the design development stage we will get to explore lots of ideas but you can start the process now by considering answers to questions as such:

  • “Should we build to the boundary, or is it possible to retain access to the garden from the front of the property by building an extension that is less wide?
  • “Is there a manhole cover in the side area, and what will happen to the existing drainage and soil vent pipes in this area?
  • “How can we maximise the light from the side return extension, and should we go for a flat roof or a pitched roof?
  • “How can we rearrange the kitchen, and will there be enough space for an island unit?
  • “How will the second storey of the side extension relate to the rest of the first floor layout?”
  • “Is there a bedroom on the ground floor that we wish to retain a window for, and should we go for a full side or a partial side extension?”

Side house extensions London architect guide – Types and options for your home project

Side Return House Extensions | Side return extensions can be either single storey (for reasons really unknown, they are often called “side returns”) at the side/rear part of the property, or double storey across the whole of the side part of the property.

Subject to planning approval, two storey side extensions often include the conversion of a garage on the ground floor and building on top of it to add more bedrooms and bathrooms to the existing first floor.

Lean-to Extensions | Lean-to extensions are small side extensions, often with a pitched roof that offers supplementary space to what used to be the utilitarian part of the house and where most kitchens are now located. For single storey side extensions a key decision is about the roof profile.

Tiled or slated pitched roofs with standard rooflights tend to appear more in-keeping with the existing property, and they reduce the effect of the extension to the neighbouring property; such extensions can be fully glazed creating a contemporary feel to the new space added.

Flat roofs add a more modern feel and they tend to provide greater internal headheight and a more generous sense of space. They can be fully glazed or partially glazed depending on cost, aesthetic preferences, and the position of any high level kitchen units in the area immediately underneath the roof.
