Why Extra Rooms are not your average supplier of garden offices and garden studios!

Bespoke garden rooms

At Extra Rooms we build all our garden rooms ourselves from scratch. As a result you can have any shape, size or configuration that you want - it’s all about what suits you and your garden and at no extra cost. See our garden office case studies.

For example; if you want your garden building to be extra-green we can build it with a sedum roof and sheep's wool insulation. Or, if you plan to use your garden room as a gym we can install bespoke wiring and electrical sockets to accommodate gym, audio and visual equipment.

Our clients spend a lot of time in their garden buildings and therefore it’s imperative that our attention to detail and quality of service ensures a good experience for years to come. Take a look at our specifications.

Construction of our garden offices

We construct all of our garden offices and garden pods by hand. Unlike many of our competitors, at Extra Rooms everything is screwed together and not nailed. This shows in the durability and strength of our garden buildings. Click here to see how strong they actually are.

Timber-framed and plastered

Even though our garden buildings are designed to blend effortlessly into the environment they are in, they couldn’t be further away from the outdoors internally. All our garden buildings are plastered and painted for that real room feel in advance and are finished to the same standard as a room inside your house.


All of our garden rooms are fully plastered and have insulated walls that are treble lined, 4 inches to 5 inches thick, providing a cavity with extremely high insulation. As well as being extremely sturdy and well-insulated, this also allows us to use real house windows and doors.


As standard, all our garden buildings come with doors containing insurance approved 5 lever locks and double glazed windows that have keyed locks. Construction grade timber is used throughout and is from sustainable sources. No MDF is used as some regard it as carcinogenic.

Installation of our garden offices

Nearly all our installations are completed in just one single day so we can provide you with your dream garden building with minimum disruption. See our time-lapse video.

How much does a garden office cost?

Costs work out on average at around £100 per sq.ft. for our standard specification, fully insulated and complete ready to use, see our specifications, rising to £210 per sq.ft. for our specialist sound proofed music studios but the top spec versions consist of two buildings sleeved inside each other for maximum soundproofing for drummers etc, but they are a separate category of specialist buildings.
