Quick Answer

A My Retreat garden room can become a home office, gym, teenage den, games room, cinema room, garden studio or garden bar — and often more than one of these over its lifetime. Every room starts from the same fully insulated, modular-built specification from £18,376 inc. VAT, with the internal fit-out designed around your chosen use.

A Garden Room That Grows With You

When we built our first garden room, my youngest was still in primary school and my eldest was a teenager. Today they're 11 and 22 — and in between, that one room has been a sanctuary, a games room, a homework den, a party room, a home gym and an office. It has saved more than one 16th birthday from taking over the house entirely.

That's the thing about a garden room: it doesn't lock you into one use. A space designed as a home office during the working week can become a teenage den at the weekend, a gym in January, or the venue for a milestone celebration a few years down the line. We design every room with that flexibility built in from day one, because we've lived it ourselves.

How We Build: A Modular System

Once your design is finalised and the CAD drawings are signed off, your garden room is built using a modular system that minimises disruption to your home and garden.

The steel-framed floor, wall and roof sections are constructed individually in our factory in Yorkshire, to the exact dimensions of your design. While that's happening, your doors, windows and cladding are ordered and prepared to match. At the end of the four-week process, everything arrives on site in a single delivery — not a series of vans and skips over several weeks.

Less disruption, less waste

Because your garden room is built off-site in a controlled factory environment, there's no pile of raw materials being cut up on your driveway for weeks on end. It also means we can make full use of off-cuts across multiple builds, so as little as possible ends up in landfill.

Frequently Asked Questions

Can I use a garden room as a home office all year round?

Yes. Every My Retreat garden room is fully insulated in the walls, floor and roof, with double-glazed UPVC windows and heating as standard — comfortable for year-round work, whatever the weather.

What size garden room is best for a teenage den or games room?

For a games room with a pool table, sofa and TV, most customers choose a room of at least 4m x 3m. We design every room around your garden and the furniture you want inside it, so exact dimensions are agreed at design stage.

Can a garden room be soundproofed for a cinema room or music studio?

Our standard build with insulated walls, floor and roof already reduces sound transfer significantly. For cinema rooms and music studios we can specify additional acoustic insulation and door seals to reduce noise transfer further.

How long does it take to build a garden room using the modular system?

From signed-off design to completed installation is typically around 4 weeks. The steel-framed floor, wall and roof sections are built in our Yorkshire factory while doors, windows and cladding are ordered, then everything is delivered to site in one go and installed in a matter of days.

Is the modular build method more environmentally friendly?

Yes. Because the structural sections are manufactured in a factory environment, we can make full use of off-cuts and minimise waste sent to landfill, compared with a traditional on-site build where materials are cut and discarded as work progresses.

Can one garden room serve more than one purpose?

Absolutely — and most do over time. A room designed as a home office during the week often becomes a teenage den or games room at weekends, a gym in January, or a party room for a milestone birthday. We design with this flexibility in mind from the outset.
