SINGLE STOREY EXTENSION FEATURES

Say goodbye to ‘one-size-fits-all’ extensions. We give you full creative control over your extension’s design, and we’ll be right by your side with our expert advice and recommendations throughout the process.
Thanks to our huge range of customisation options, you can tailor your extension down to the smallest detail. From selecting the roof style to choosing the colours of your cladding, you have the freedom to personalise your extension as much or as little as you like.

Do you prefer a traditional pitched roof or a neat, minimalist flat roof? Bright or muted colours? Slate or shingle tiles? Whatever your vision, we’ll make it a reality.

Below, we’ve explored all the options you have when designing your extension. If you’d like to know more, feel free to get in touch with our team – we’ll be happy to answer your questions and arrange a visit to our showroom.

EDWARDIAN

A classic shape made up of three sides sloping towards the ridge.

LEAN-TO

A simple, mono-pitched roof that offers clean lines. Perfect for adding large opening vents.

EDWARDIAN HIPPED

Similar to the Edwardian, but with four sides instead of two. Comes with an aluminium box gutter.

LEAN-TO SIDE HIPPED

Same shape as a lean-to, with the addition of two hips creating two extra sloping sides.

GABLE-END

A contemporary look with two sides sloping towards the ridge. You can choose to add a glass gable frame to the front to maximise natural light.

I recently had an Edwardian hipped extension completed by Single Storey Extensions, with Ash tiles, and the outcome was amazing. The level of professionalism demonstrated by their team from the beginning to the end of the project was truly impressive. Their attention to detail and commitment to quality was evident in every aspect of their work. Getting Single Storey Extensions to handle our Edwardian-hipped extension was an excellent choice. I strongly recommend their services to anyone looking to undertake a similar job. Their dedication to delivering top-notch results is genuinely praiseworthy.
