When thinking about your project you must consider that garden studios must be constructed 2 metres from your house and also that it must not take up more than 50% of your total garden area.

Bespoke Build

We design and build bespoke studios for office, arts / crafts, music (sound proofing), fitness studios, lounge, swimming pool rooms or annexe… What ever your plans we can help you build your dreams.

Planning permission is necessary for customers living in an Area of Outstanding Beauty, A Conservation Area, in A National Park or A World Heritage Site. This is a result of differing planning rules in these areas and also because of their distinctive character and natural beauty.
