Home Extensions in Sunderland
If you love where you live but you’re running out of space, a home extension in Sunderland can be the smartest way to improve your home without the stress of moving.
At Windsor Roofing, we carry out home extension work in Sunderland and across surrounding areas (up to around 45 miles). Whether you’re planning a single-storey extension, extending to the rear for a bigger kitchen, or adding extra living space for a growing family, we’ll help you take the job from idea to finished build with clear advice and a solid standard of workmanship.
Why extend your home
A well-planned extension can transform how your home works day to day. Common reasons people extend include:
- Creating a larger kitchen and dining space
- Adding a family room or snug
- Building a home office
- Improving layout and flow on the ground floor
- Adding practical space like a utility room
- Making room for family life without moving house
An extension can also increase your property’s value, particularly when the extra space makes the home more usable and attractive to buyers.

The types of extensions we build
Every property is different, so we start with a site visit to understand your home, access, and what you’re aiming to achieve.
We can support projects such as:
- Single storey extensions
- Rear extensions for open-plan kitchen living
- Side extensions to widen key rooms
- Wrap-around extensions (where suitable)
- Associated works like roofing, brickwork and repointing
If your plans involve roofing work as part of the build, it helps having one team that can handle both building and roof elements properly.

Planning, building regulations, and structural considerations
Depending on the size and style of your extension, you may need planning permission, or it may fall under permitted development. Most extensions also require Building Regulations approval.
If you’re unsure what applies, we’ll talk you through it in plain English and help you understand what needs to be in place before work starts.
What People Say About Us
Family-Run Roofing You Can Rely On.
Debbie
Roof Replacement
"I can’t speak high enough of John and his son, Anthony. My 101 year old Mum had water coming in through her kitchen ceiling following a recent storm and my friend recommended these guys having used them extensively in the past. They came out and gave a quote. However, once they started the job it quickly became apparent that the job was a lot bigger than first anticipated thanks to some previous workmanship resulting in the wall not even being attached to the house!! The job was completed today and I’m over the moon with the result. Would not hesitate to recommend for any roofing jobs."
Laura
Window Fitting
"John and his team were great, John came out promptly and looked at the job in hand and provided a quote in a timely manner, once we booked the job he kept in contact to come out and fully measure up and then organised the window install, john kept me updated all the way through and as soon as the window was made and ready organised a date to complete the job ,John and his team were lovely and very professional, really great job completed and they tidied up everything after, we would definitely use them again "
Richard
New Roof
"We knew from the very first conversation with the lady in the office that this would be a great firm to deal with. We were given an appointment for a quote and Anthony turned up bang on time as agreed. We agreed the cost and timing straight away. This is a family business & John & Anthony were fantastic to deal with. You can really tell that they care about their work & have great attention to detail. Their team of roofers were a great bunch of guys & they tidied up afterwards. Highly recommended. Wouldn’t hesitate to use them again."
Home Extensions FAQs
Do I need planning permission for a home extension?
Not always. Some home extensions can be done under permitted development, but it depends on the size, height, location, and how close it is to boundaries. Things like conservation areas, listed buildings, and previous extensions can also change what’s allowed.
The safest way is to check early, because getting this wrong can cause delays and extra costs later.
How much does a home extension cost in Sunderland?
Extension costs vary massively depending on the size, access, groundworks, and the finish you want. A simple shell is very different from a fully finished extension with electrics, plumbing, heating, plastering, and high-end doors or glazing.
As a rough guide, most home extensions are priced based on the scope and spec, not just the square meter size. We can provide you with a more precise, practical quote once we understand what you want to construct and what you want it to include.
How long does a home extension take?
Smaller single storey extensions can be quicker, while larger or more complex extensions take longer, especially if there are structural changes, drainage work, or planning conditions. We’ll talk you through a sensible timescale once we’ve seen the site and understood the build.
