What is a Rear Extension?

A rear extension is one of the simplest kitchen extension designs. It involves opening up the rear of a property and extending it into available garden space. By adding extra square footage to your property, a rear extension gives homeowners more functional space.

There are many reasons why people might be interested in a rear extension. A small rear extension can create a peaceful retreat that is flooded with natural light – perfect for relaxing alone or intimate gatherings. You may be looking for an open-plan kitchen and dining space for parties or extra space for a growing family.

Design and Build Services for Rear Extensions

The Plus Rooms team is highly experienced in designing and building extensions in an array of styles, and for various types of properties. We will go to great lengths to create an extension that fits seamlessly with the rest of your home, whilst also creating a compelling new focal point so you can get the most out of open-plan living.

One of the benefits of a single-storey rear extension is that it creates a seamless connection between indoor and outdoor spaces. We can use bi-fold doors to open up your kitchen into your garden space, creating a brand new living and entertaining area whilst also bringing in all that natural light.

While functionality is key to a great extension, we are also passionate about design. A rear extension can add a modern flair to period properties or provide additional warmth and comfort. Alternatively, a contemporary extension can be both clean and practical yet visually captivating.

How Much Does a Rear Extension Cost?

Multiple variables can affect the cost of a house extension project. These can include whether you own a terraced, semi-detached or detached house, as well as the size and roof type of your desired extension. For instance, a 3m x 3m flat roof rear extension has an estimated cost of £60,000.

We look to provide accurate cost projections from the outset and will be transparent about any additional costs. As part of this, we’ve created a clear and simple extension cost calculator – which includes 3D models of how your chosen extension would look.

All of our estimated costs for extensions include building work, plumbing, electricity, glazing, external doors and applicable VAT.
