Extensions That Become Part of Your Home
A single storey extension is one of the most impactful improvements you can make to your home. Whether you need a larger kitchen, an open-plan family space, a dedicated home office, or simply more room to breathe — a well-designed extension delivers it permanently.
At Northern Trade Windows, we offer two types of single storey extension: tiled extensions, which are built to look and perform exactly like a traditional brick-built addition, and orangeries, which combine solid brick or stone pillars with a signature roof lantern for a more premium, architecturally distinctive result.
Both are fully insulated, guaranteed for 10 years, and designed specifically around your property. Our experienced team surveys, designs, and builds every project from our base in Pudsey, Leeds — serving homeowners across Yorkshire.

Orangeries
The premium single storey extension — solid brick or stone pillars, a flat perimeter roof, and a stunning central roof lantern that floods the interior with natural light. Architectural, permanent, and luxurious.

- Premium property value uplift
