"We did some price/quality testing, but returned to you. You have the best offering; flexibility of design; best insulation; easiest and cheapest foundations. You have got it right." Philip Evans, Barcombe, East Sussex.

Enjoy all year round living* in your home-from-home in the garden. Each office and annexe is filled with double layers of breathing insulation, for comfortable living however the British weather behaves. During heatwaves, frosts, rainstorms and droughts your garden office will need little heating, no air conditioning and will use small amounts of electricity.

You will be as safe as houses. Every home garden office and granny flat is designed for you by Gordon Smith RIBA. We take care of you every step of the way. Designed by an architect, built by our professional construction teams and backed by our 10 year guarantee. They are simply the best. 

Local materials are best. 25% of CO2 emissions come from domestic buildings to create global warming. We use materials made in the UK to reduce travel distances. Who wants wood that has travelled from Eastern Europe or South America?

We know you care about the environment. To help reduce CO2 emissions we use materials made with low levels of energy and few chemicals.  Our garden offices are carefully built with eco-friendly materials and a strong timber frame made with FSC wood. We use two layers of insulation and breathing technology to protect computers, books and musical instruments all year round.

We use eco friendly materials. All our garden rooms are clad on the outside with Scottish larch. Larch is totally water resistant. Historically it is used for building boats. Our office interiors are traditionally plastered. We use handmade, wooden double-glazed doors and windows. They are made in England and are guaranteed for 10 years. Our roofs are tiled with cedar shingles that mature and mellow with the years.

We can add a loo or shower room. The flexible design of our studios and granny annexes allow us to add individual features for you.

Don't worry about planning permission. We organise the planning permission for your garden home office, if you need it. The rules for planning permission for English garden buildings changed recently and they are explained on our planning permission page. If you can position your office two metres from any boundary you are unlikely to need planning permission in England. In Scotland and Wales the old rules apply.

Will your garden office need building regulations? A larger office may need building regulations. Building regulations are complex and boring, so we take away the tedium and handle the application for you. All offices with an area of more than 30sq metes have to meet building regulations. Offices with a floor area between 15 and 30 sq metres and built within a metre of a boundary also have to meet building regulations. But, no problem, all our buildings are built to current building regulations standards.

We know you are busy so all our offices and granny annexes include project management from start to finish. We design, we organise and we supervise. Gordon and I are on site on the day that construction starts and return at the end of the building work to check that all is well. It always is. In the meantime, you can get on with your life.

And Finally a quote from eleven year old Daisy Boggan: - " This is the first summer holiday that I can have my friends round to play. In the past if we made too much noise we disturbed my dad. Now I can make lots of noise whilst he's in his garden office."
