A house extension is one of the smartest ways to add both space and value to your home without the upheaval of moving. Whether you need an extra bedroom, a bigger kitchen, or a home office, here’s what to consider before you start.
Types of house extension
The right extension depends on your home and your budget. Single-storey rear extensions are the most popular, ideal for open-plan kitchen-diners. Side-return extensions make clever use of the dead space beside many Liverpool terraces. Double-storey extensions add space upstairs and down for better value per square metre, while loft and garage conversions transform space you already have.
How much does an extension cost?
As a rough guide, a single-storey extension in the Liverpool area typically starts from around £1,800–£2,500 per square metre, depending on size, specification and finish. Kitchens, bathrooms and bi-fold doors push costs up. Every project is different, so the only accurate figure is a detailed quote based on your plans.
Do you need planning permission?
Many extensions fall under “permitted development” and don’t need full planning permission, but there are limits on size, height and how close you build to boundaries. Conservation areas and listed buildings have stricter rules. Whatever the case, your project will still need to meet Building Regulations, which cover structural safety, insulation and drainage.
How long will it take?
A straightforward single-storey extension usually takes 8 to 12 weeks on site, though design, planning and Building Control approval should be factored in before work begins. A realistic timeline from first enquiry to finished room is often three to six months.
Choosing the right builder
The success of any extension comes down to the team building it. Look for a builder who is fully insured, offers a clear written quote, and can show you completed local projects.
