Types of House Extensions We Build
Single Storey Extensions
Single storey extensions are a popular way to add functional living space at ground level, often incorporating rooflights or large glazed doors to maximise natural light.
Double Storey Extensions
A double storey extension increases living space across two floors, commonly adding bedrooms, bathrooms or larger family layouts while maintaining balance with the existing home.
Side Return Extension
Side return extensions make use of unused side space, typically on terraced or semi-detached homes, to widen and improve ground floor layouts.
Rear Extension
Rear extensions extend out from the back of the property and are often used to create larger kitchens, dining areas or family spaces with improved access to the garden.
Wraparound Extension
A wraparound extension combines a rear and side extension to maximise ground floor space, often creating large open-plan kitchen and living areas.
Over-Structure Extension
Built above an existing structure such as a garage or ground floor extension, over-structure extensions add valuable space without reducing garden area and require careful structural planning.

House Extension Projects
“Owen was the only person who seemed genuinely interested in finding a solution”
Having a two-storey extension built is a big undertaking, and ours certainly came with its fair share of challenges. We hit an unexpected issue with Yorkshire Water pipework while digging the foundations, and Owen was the only person who seemed genuinely interested in finding a solution rather than seeing it as a reason to walk away. He liaised directly with Yorkshire Water and came up with an alternative foundation strategy that kept the project moving.
The end result has completely transformed our home and the way we live. Our new kitchen has become the social hub of the house, we finally have the space to entertain friends and family, and there’s now comfortable additional space for relatives to stay when they visit. Even my mother-in-law comments on the quality of the workmanship every time she’s here!
Building work is always disruptive, but Owen and the team at Farswood Construction made the process as smooth as possible, kept us informed throughout, and delivered a fantastic finish. If we were starting the project again tomorrow, I wouldn’t hesitate to choose Owen and the Farswood Construction team all over again.
“Costs matched the quote well and any potential extras were discussed and agreed”
Owen and the team did a great job of our extension and kitchen re-fit. Owen was really easy to communicate with throughout and kept us updated regularly. Costs matched the quote well and any potential extras were discussed and agreed. Our old house gave them some issues but they always had a solution and we are really happy with the finished job. Everyone was polite, clean and tidy. Would highly recommend Farswood Construction and gladly use them again
“I am so chuffed with our new home”
I am so chuffed with our new home, and it’s huge thanks to Farswood Construction for their care, guidance and hard work that we have it. It was a big project! A two-storey side and rear extension to take our tiny galley kitchen into a lovely open-plan kitchen-diner with a utility room and downstairs toilet attached, plus a new bedroom with en-suite above. I also had the loft converted at the same time to add a further bedroom with en-suite bathroom in the attic, which necessitated the ceilings in the bedroom and landing below to be lowered.
I needed to get our work done in a couple of main stages as my budget allowed, and this was not just accommodated without any issues, but I was advised on how to do this in the most economical way.
I found Owen at all times to be honest, trustworthy and reliable, and those he contracted to work on our home to be kind, helpful and good at what they do. I felt that we were treated like human beings and that those involved had a positive attitude – I’ve not had any building work done before, and the teams were happy to advise when I needed some help with making decisions.
I don’t know any building project where there isn’t some sort of an issue which crops up at some point – but it’s how it’s dealt with which is key. At all times Owen and those working for Farswood were focused on practical problem-solving and we are absolutely delighted with the results.
Groundworks, Foundations & Structural Work
All successful extensions begin with solid preparation. Our in-house team carries out all necessary:
● Groundworks and excavation
● Foundations and drainage
● Demolition and strip out
● Structural steelwork and load-bearing alterations
By managing these critical stages ourselves, we maintain full control over quality, timescales and site safety throughout the build.
Design, Planning Permission & Building Regulations
Navigating planning permission and Building Regulations can feel overwhelming, but we guide you through every step. Depending on your project, your extension may fall under permitted development, or it may require full planning approval from Leeds City Council.
We assist with:
● Design development and layout advice
● Planning applications where required
● Building Regulations compliance
● Liaison with inspectors and sign-off
Our goal is to ensure your extension is fully compliant, structurally sound and future-proof.
Plumbing, Electrical & Interior Fit-Out
Once the structure is complete, we carry out all internal works to bring your new space to life, including:
● Plumbing and heating installations
● Electrical wiring and lighting
● Carpentry and joinery
● Plastering and rendering
● Tiling, flooring and decorating
Because everything is handled by our own trusted trades, you benefit from a coordinated, turn-key service with consistent workmanship throughout.

How much does a house extension cost in North Leeds?
The cost of a house extension depends on size, design complexity, ground conditions and materials. We provide accurate quotations following a site survey and design review. Most of our customers’ projects range from £50,000 – £350,000 worth of work, but not all jobs will be the same. Get in touch for a free site visit to start your free quotation.
Do I need planning permission for an extension?
Some extensions fall under permitted development, others require planning permission. We’ll advise based on your property and manage the process if needed
How long does a typical extension take?
Most extensions take between 10–16 weeks once work starts, depending on size and complexity.
Are you insured, and how do payments work?
Yes. We are fully insured with £5 million public liability cover. Every project runs on a written contract with staged payments, so you pay as each stage of the work is completed rather than a large sum up front.
What type of house extension should I choose?
Common options include single-storey, double-storey, side-return and wraparound extensions. The best option depends on your property layout and space requirements. We will discuss options with you to make sure you are happy with the proposal and what you envision for the end result.
Can you work while we live in the house?
Yes. Most clients stay in their homes during the build, and we plan work to reduce disruption.
Will an extension increase my property value?
Many extensions significantly increase property value, particularly when adding usable living space or improving layout functionality. By how much depends on your local area, property type and future valuations. In order to get an accurate estimation, book a valuation on your property with an estate agent.
Do you handle foundations and structural work?
Yes. We carry out all groundwork, foundations and structural alterations as part of our service.
Can you help with planning and design?
Yes. We assist with planning, design coordination and Building Regulations approval.
Do you build extensions in Horsforth and Roundhay?
