Garden Room Sale - 10% Off!

As we step into 2026, many of us are looking at our homes and wishing we had just one more room. Whether it’s needed as an office, a gym and fitness space or a comfortable space for family to stay, the desire for extra square footage is higher than ever.

At Cosy Garden Rooms, proud winners of the UK Business Awards 2025, we specialise in creating that “missing room” without the stress, cost, or months of disruption associated with a traditional home extension.

Why choose a garden room in 2026?

The way we live is changing. More and more homeowners are moving away from standard extensions in favour of bespoke garden buildings. Why? Because they are typically faster to build and much cheaper.

From a high-spec home office that allows you to truly leave work at the door, to a luxury annexe for multigenerational living, we design and build to your exact vision. Guided by our belief in Any Design, Any Size, Any Use, you never have to settle for an off-the-shelf solution that almost fits; we create the one that’s right for you; bespoke garden rooms.

The Cosy Garden Rooms difference

We are proud to be one of the most customisable garden room providers on the market. Every room is hand-built with meticulous attention to detail and backed by our comprehensive 10-year guarantee.

Every build includes as standard:

• Complete bespoke design with unlimited CAD revisions

• Professional foundations, including a solid concrete base

• Year-round comfort with full insulation to floors, walls and ceiling

• Fully serviced electrical package, with discreet recessed downlights and heating

• Premium finishes, including high-quality flooring, decoration and a choice of contemporary cladding

• Quality joinery, with premium UPVC windows and doors (aluminium and other bespoke options available)

Around 99% of our garden rooms are built under permitted development, meaning planning permission isn’t required. We take care of the technical details so you can focus on the design.
