House Extensions

Why move when you can have a fabulous home extension?

Extending your current home could be the answer to all of your space-related problems. A roomy, brand new single-storey extension can be pretty much anything you want it to be. Once completed, we’re confident that you will love your old home more than ever. Pennine can build your home extension from scratch and amongst many things, turn it into a luxurious dining area, stunning lounge or home workspace. We’ll do so taking all the right and necessary steps.

As it’s very much your project, you get the final say on any windows, doors, walls and pillars added to the extension. You’re welcome to immense yourself in the assignment as much as Pennine promises to.

Stylish, affordable, simple.


Pennine has unrivalled experience locally for extensions...

Imagine how difficult it is trying to find a builder, architect, plumber, plasterer and installer you can trust. You also have to rely on them all to stick to your budget and meet your timescales.

It’s far simpler, and far less stressful, just giving Pennine responsibility for the entire project – a respected firm that won’t let you down.

Dream Big – Pretty much anything is achievable and you can see all of your big ideas brought to life via our state-of-the-art 3D software. Use of this technology enables you to see your extension like you never could have imagined.

Hassle Free – You won’t find the process any hassle at all. The boring stuff like organising planning permission and building regulations approval can be sorted by Pennine.

Huge Choice – You will find it difficult knowing where to start with your extension as we have so many possibilities in terms of roofing options (including traditional tile or slate and modern composite) and a fine selection of window and door styles.

Feel Involved – Creating a extension will feel as much of an accomplishment for you as it does for Pennine as you will be given licence to get involved.

Surprisingly Affordable – You can pay for the extension over a period of 5 to 15 years using one of our monthly payment plans.
