Expert Extensions
Choose a Shape and Size

To create an extension that truly meets your needs, it’s important to consider both the size and the most suitable location within your property. This involves assessing the available space, your budget and how the new structure will integrate with your existing home. At DECREW, we explore all viable options following a site survey and a detailed discussion of your requirements.

We construct all types of property extensions, including:

3D rendering of a house with a white upper section and a modern yellow extension featuring large glass doors.

Rear Extension

The most popular choice, creating bright open-plan kitchens, dining or family spaces at the back of your home.

Abstract architectural model featuring a combination of a grey house, a white cube, and a yellow accent, set against a white background.

Side Extension

Transforms side space to widen the home and improve internal layout without compromising the garden.

Modern architectural rendering of a two-part house featuring a gray and white upper section and a bright yellow lower section with large glass doors.

Wrap Extension

Combining rear and side extensions, this L-shaped design maximises ground floor space and brings light into every corner.

A modern house illustration featuring a yellow section, white walls, and a gray roof, viewed from an angle.

Double Extension

A two-storey extension adding space on both levels, ideal for growing families and long-term value.

Many house extensions can be completed without full planning permission; however, larger or more complex builds may require formal approval before construction begins. Projects must meet specific criteria, such as limits on how far an extension can project from the existing property.

Our builders have extensive experience working across all planning scenarios. As part of our design-and-build service, we manage compliance with relevant regulations and provide clear guidance on whether planning permission is required for your project – without affecting the comprehensive service we deliver.
