Some thing we are often asked is, ‘will I require planning permission’… The answer is no, it is not usually required as our garden rooms comply with permitted development laws. Planning differs if you live in a listed building, or conservation area. We are happy clarify any uncertainty and answer any questions you may have.

Paul, Neil and Ziggy are amazing. The quality of the studio they have built is superb in every way. Working to extremely high standards both in the quality of materials they use and their attention to detail. I was consulted throughout the project and are happy wherever possible to incorporate changes. They are also a pleasure to have around and I will miss them. The studio exceeds all my expectations – Paul and his team have made a dream come true and I can’t thank them enough.

This Garden studio is very well insulated with 90mm Celotex in the walls, 100mm beneath the floor and up to 140mm to the ceiling. In fact, this beautiful room can be used all year round.

The finishing specification on this build was really high, for example, black aluminium windows and doors. Finished with larch cladding all round.

Measuring 6m wide and a total of 4m deep this studio on the lake even comes with a bespoke glass viewing plate in the deck. In addition there is also a beautifully simple glass balustrade surrounding the viewing platform.
