We can help you beautifully grow your home…

There’s been a huge surge in the number of people extending their properties and you can have enormous fun extending yours. Your purpose for adding an extension to your home could be down to an urge to have a more luxurious dining space, lavish new lounge or extra bedroom to accommodate friends and family. Hazlemere is the perfect company to take on the project as we can oversee everything involved in designing and installing the extension. Extensions are something we have specialised in for years, so we know what makes a great extension. You’re assured of no headaches when Hazlemere is looking after things.

No project is too big for our team – we always deliver.

Ask Hazlemere about our flexible finance options if you need help funding your home extension.

Hazlemere builds home extensions like nobody else...

To successfully construct a home extension you need a reliable builder, architect, plumber, plasterer and fitter. You also need to be sure that they will stick to your budget and meet your personal timescales.

You would be far better solely appointing Hazlemere to manage the entire project as we can conduct all of these roles, and promise to do so without leaving you out of pocket or completing them late.

Dream Big – We are as keen as you are to come up with an extension that fulfils your entire set of requirements. Use of our 3D state-of-the-art software will ensure that your extension incorporates everything you want to avoid any disappointment.

Hassle Free – Some extensions are subject to planning permission and building regulations approval. Hazlemere will take responsibility for organising this when you need it.

Huge Choice – You can accomplish so much thanks to the depth of choice you have at Hazlemere. We supply composite tile and slate roofing systems, ceilings and an impressive stock of window and door styles.

Feel Involved – It’s your extension, so you should feel closely involved with the project, from start to finish. We welcome your input.

Surprisingly Affordable – You don’t have to pay for your extension in one lump sum. We allow you to spread the cost to make it more affordable for you.
