Answered: 5 questions about permitted development garden rooms
Are you considering a garden room might help solve the space woes in your home? Here are 5 questions answered on getting more space with a garden room without the need to jump through planning permission hoops.
1. Does a garden room need planning permission?
For a free-standing garden room to be classified as permitted development (planning permission not required) floor area must be limited to 25 square metres and the remaining garden space (after construction) must not be less than 25 square metres to the rear or side of the garden room.
2. Great news! Any restrictions on the design & construction for such a garden room?
To stay in the permitted development garden room guidelines, ensure your construction’s roof style is no more than 4 metres for a pitched roof or 3 metres for a mono-pitched sloping roof.
Also, be sure to keep windows within 1 metre of a neighbour’s boundary and watch for sun glare which might occur with glass installation.
3. Can my permitted garden room be insulated, plumbed and wired?
A garden room can be fully insulated, double glazed and electrically wired complete with broadband. Of course, if you have the budget, you’ll even have enough space in your 25 square metres to install a kitchenette and small shower room.
4. Perfect so! I might even it rent out!
Sorry - no. An exempted garden room is not supposed to be used as accommodation or to be lived in.
You’ll need planning permission to build a garden room to be used as self-contained accommodation or for commercial purposes. Building requirements include providing parking and separate connection to services – check with your local council for further details.
5. Ah – Ok. Let’s keep it simple then. Say I just wanted a permitted garden room for a home office, games room or a teenager’s den - what is the cost?
A flat-pack unit installed & painted complete with doors, windows, roof insulation and wired for electricity start from €8,500.
A fully insulated (roof and wall), timber frame garden room (on block foundations) which includes plumbing, electricity, sewage and broadband will cost you anywhere from €15,000-€22,000.
Another option is to post a job with Onlinetradesmen and explore design options with a fully qualified carpenter to build your very own bespoke garden room (handy for odd-shaped gardens)
Or, if you need help with getting a flat pack garden room erected, then a handyman might be just what you need.
