Garden Rooms
Barnwood Carpentry specialise in the design and construction of high quality, specifically-designed, all-year-round garden rooms and studios of all sizes from smaller home offices to entertainment pavilions. We work alongside associated trades to provide a fully-inclusive turnkey, garden building solution, designed with its intended purpose in mind, whether it be exercise space, entertainment area, workshop, or extended living space.
Our Garden Rooms
In recent years we have seen more and more homeowners looking to extend the living space and maximise the value of their existing properties. Garden Rooms are becoming an increasingly popular and affordable way to achieve both these aims, often within permitted planning.
Gardens rarely offer straight lines and right angles! At Barnwood Carpentry, we wanted to bring the market much-needed flexibility in design and build so we aren’t as limited in what we can achieve for you. We fully utilise the space available and build you the garden room that fits your own individual needs.
Our Garden Room Turnkey Service
The team at Barnwood Carpentry approaches every project as a blank canvas onto which we design a unique garden building to suit your specific needs whilst best utilising the space available.
At our first meeting, we will take the time to fully understand the intended use of the building, the layout, and the space available. We will discuss and explain the different options available to you and how these affect the overall aesthetic and cost.
Our quotation will clearly show the scope of work and materials to be used and give an overall fixed price wherever possible.
If you require drawings to submit for planning permission, we will refer you to our draughtsman who will be able to provide you with a quote to produce these for you.
Barnwood Carpentry will project manage the entire build from groundworks to decoration. We have a team of associated tradesman who work with us to deliver electrical work, plastering, decorating etc, taking the worry of coordinating different trades off your shoulders.
At the end of the build, your garden room will be fully insulated, weathered, plastered, and decorated, with all doors, windows, flooring and second fix carpentry completed. It will be ready to be used by you for many years to come.
FAQs
Outbuildings can be considered permitted development (not requiring planning permission) if they meet certain requirements, which can be found here. If your garden building does require planning permission, we will refer you to our draughtsman who will quote to produce a set of drawings for submission.
Garden rooms are exempt from building regulations if:
- The internal floor area is 15 square metres or less, if within 1 metre of any boundary
- or the internal floor area 30 square metres or less, if more than 1 metre from any boundary.
Visit the planning portal for more information on building regulations.
The running of water to your garden studio within permitted development very much depends on proving that the use of the garden studio and its subsequent water supply are incidental to the activities of the main habitable dwelling. Examples of this could be a particular hobby and/or activity not conducted within the house.
