If you’re interested in renovating your home to make the most out of your interior space, a rear house extension could be exactly what you’re looking for. As one of the simplest extension designs, a rear extension is an efficient and effective way to create a brand new living space that represents that perfect combination of style and function. In this article, we’ll take a look at different features of rear extensions, some practical considerations to bear in mind and, of course, some inspiring rear house extensions designed and built by the Plus Rooms team.

Types of Rear Extension Designs

For terraced, semi-detached and detached properties, extending the rear of the home into the garden space is a simple way to add on to your kitchen, dining and living areas. These typically extend the home by 3-6 metres and can include some of the following features:

  • Pitched roof extension – Pitched roofs can prevent pooling water and snow, which makes home maintenance easier and helps to prevent leaks. They also increase ceiling height, so the extension as a whole feels more spacious and inviting. The roof can be made of any traditional roofing material and there’s also the option of installing skylights, accentuating key design features with a gleam of natural light.
  • Flat roof extension – Flat roofs give homes a more modern, contemporary feel with clean structured lines. They not only offer a sleek and streamlined shape but also require less structural engineering than similar roof types, meaning they can often be a more cost-effective solution for your new extension.

What to Consider When Designing a Rear House Extension

  • Planning permission – Keep in mind that the planning permission process may be more complex if you live in a conservation area or a listed building. Generally speaking, only half of the land around the home can be used for an extension, they cannot extend higher than the original roof, and no higher than 3 metres in height within 2 metres of the boundary. Your project manager will be an invaluable resource in handling the permission process and ensuring that your extension is fully compliant.
  • Single or double-storey – Typically, single-storey extensions extend the kitchen, living area, and/or dining area while double-storey extensions create additional space for bedrooms and bathrooms. A single-storey extension is usually a more cost-effective solution, as it is easier to obtain planning permission and should require less building time than a double story extension.
  • Light – Because an extension lengthens a home, you’ll want to make sure that there is ample lighting throughout. Fortunately, our team offers an array of solutions to bring in as much natural light as possible. Whether it’s through skylights, large windows or bi-folding doors, we’ll make sure that your extension is a bright and welcoming space.

Rear House Extension Designs to Inspire You

Clever use of space in Wimbledon

When space is precious, the right design will make all the difference! This rear extension focuses on the kitchen – one of the most frequently used areas within the home. By extending into the garden with a high, vaulted pitched roof to add considerable volume, the space feels generous and airy. A simple, clean design complete with skylights makes it the perfect space to gather and entertain guests.

Lighting it up in Wandsworth

When building this rear extension in Haslemere Avenue, our goal first and foremost was to maximise space and bring the outdoors in. The flat roof creates a contemporary canvas to feature the three triple-glazed skylights, creating a space where traditional design meets modern chic. This particular extension is raised from the garden, so we decided to utilise patio space and bi-folding doors to create a multi-purpose living, dining and entertaining space.

Family Functionality in Bromley

Our task was to extend this 1930s property into a family-friendly space that felt bright and open whilst still retaining a sense of warmth. Therefore, we decided to install large sliding doors and roof glazing to bring in all of that wonderful natural light and embrace neutral sandy tones to ensure the space doesn’t feel too clinical. Of course, there is also now an abundance of space so there’s room for all of the family – and then some!

Indoor Outdoor Lifestyle in Saint John’s

Extensions don’t just help you utilise the space you have indoors, they help you get the most out of outdoor spaces too. This flat-roof rear extension in Saint John’s shows how a relatively modest extension can expand your home to the outdoors in good weather. With the seamless flow between indoors and outdoors, not to mention pops of bright, evocative colours, this space represents the best of fun, modern style without being too overwhelming.

Traditional Feel Meets Modern Living in Petergate

Our goal when designing an extension for this terraced Victorian property was to make the most of modern functionality whilst keeping its traditional spirit alive. The vaulted ceiling and gable roof is a hallmark of classic interior style, and the exposed brick wall creates a ‘modern farmhouse’ aesthetic. While the fold-out doors are a modern touch, they help expand the home’s entertainment and family living space further out into the garden.
