The team you sent were lovely! I’d happily have them back, they were probably the most polite, courteous and hard-working tradespeople we’ve had on site. They were an absolute pleasure and they’ve done a brilliant job, please thank them for us and I hope they have a safe trip back.

Available in over 60 sizes, the innovative Key Studio is warm and inviting, with contemporary lines and crisp design allowing the soft Thermowood’s natural tones to make their own style statement.

Garden Rooms

The Key Studio range offers the same traditional style elements as our Classic range but with a modern twist. The soft style of the Thermowood creates an entirely new look when combined with the mono pitch roofline. And with the option to select the colours of the chassis, fascias and windows, from striking black to contemporary grey (or a combination of the two), you can design and create a truly bespoke, modern garden studio.

Strong & Durable

The Key Studio offers the same build quality, strength and rigidity as the rest of our SMART® ranges through the TuSC®   construction. This includes a pressure-treated chassis, double-glazed windows and doors and a mono pitched roof. All these elements combined create a durable, strong and unrivalled garden studio space that won’t require any maintenance for at least 10 years!

Configure How You Wish

Our range of windows and doors allows you to configure your garden studio however you wish, from bifold doors to double or porthole windows – the huge range of options will ensure you quickly fall in love with your affordable garden office, no matter what the size of your garden.
