Home Extensions Liverpool

Building an extension is the best way to get the extra space you need without the stress and cost of moving. At Glassar Projects, we’re not just builders; we’re a family-run business with over 40 years of experience turning cramped houses in Liverpool into spacious, modern homes. We handle everything, from the first drawing to the final coat of paint, making the whole process straightforward and stress-free for you.

Whether you’re in Aigburth needing a bigger kitchen, Woolton dreaming of a family room, or Childwall wanting to add value to your property, we’re the local experts you can trust. We’ve worked on homes across Liverpool, from terraced houses in Allerton to semi-detached properties in Mossley Hill, and we know how to get the most out of every square metre.

Our 4-Step Process: Simple & Stress-Free

We’ve refined our process over 40 years to make it as smooth as possible for you.

1. Design & Planning: We start with a chat to understand what you want. Our team then draws up plans and handles all the planning permission paperwork with Liverpool City Council, so you don’t have to worry about it.

2. Structural Work: Once plans are approved, our groundwork team gets to work on the foundations and structural shell. We take care to minimise disruption and keep the site tidy.

3. Building & Fitting: This is where your vision comes to life. Our skilled tradespeople handle all the brickwork, roofing, plumbing, and electrics, ensuring everything is built to the highest standard.

4. Finishing Touches: We manage the plastering, decorating, and final fittings, leaving you with a beautifully finished space that’s ready to live in.

Case Study: A Family Kitchen in Allerton

The Project: A family in a 3-bed semi in Allerton, L18, needed a bigger, more sociable kitchen. Their existing space was cramped and dark.

The Solution: We designed and built a 4m x 6m rear extension, creating a stunning open-plan kitchen-diner with large bi-fold doors opening onto the garden. We fitted a modern kitchen with an island, underfloor heating, and skylights to flood the space with natural light.

The Result: The family now has the bright, spacious hub they always wanted. The project was completed on time, on budget, and added an estimated £50,000 to their property’s value.

“We couldn’t be happier with the work Glassar Projects did. They turned our small, dark kitchen into the heart of our home. The team was professional, tidy, and finished exactly when they said they would. We’d recommend them to anyone in Liverpool.” – Sarah & Tom, Allerton

Frequently Asked Questions

Do I need planning permission for an extension in Liverpool?
For many single-storey rear extensions, you might not need full planning permission as they can fall under ‘Permitted Development’. However, there are strict rules on size and location. We will assess your project and advise you on the exact requirements and handle the application for you.

How long does a house extension take to build?
A typical single-storey extension takes around 12-16 weeks from starting on site to completion. A two-storey extension is usually 16-24 weeks. We provide a detailed project schedule before we start so you know exactly what to expect.

Can I live in my house during the build?
Yes, absolutely. We go to great lengths to minimise disruption. We’ll seal off the work area to control dust and noise, and ensure you have access to essential services like your kitchen and bathroom for as long as possible.

Are your quotes fixed?
Yes. Once we’ve agreed on the final design and specification, we provide a detailed, fixed-price quote. The price we agree is the price you pay, with no hidden extras.

What areas of Liverpool do you cover?
We cover all of Liverpool and the surrounding areas, including Aigburth, Woolton, Childwall, Allerton, Mossley Hill, West Derby, and across the water in the Wirral.
