Garden Rooms, Studios and Offices etc

Here is a brief outline of the process that I would go through to construct a garden room or studio. Bear in mind a timber garden structure can mean many things; office, spare room, summer house, workshop, shed, sauna, studio etc. the possibilities are wide.

  • Floor joists of Douglas Fir or Larch. Posts allow for building on a sloping site and sit on simple concrete cube foundations.

  • Rafters all on and framework completed.

  • Timbervent boarding provides all racking and diagonal bracing, as well as being an important part of the timber frame wall breathable "sandwich".

  • Breather membrane wraps the building, battens for cladding and tiled roof are on and the reclaimed clay are tiles being fitted.

  • Sweet Chestnut, waney edge cladding looks lovely.

  • Wool insulation throughout so 2.5 Kw stove will provide plenty of heat, a small PV panel also powers LED lights.

  • Strawboard is used to line the inside, with spare boards making ideal bunks.

Pricing

Here is an approximate guide to prices for timber buildings;

Sheds                                       £250 to £400 per  m2  
Garages and workshops         £350 to £600 per  m
Garden rooms and studios     £750 to £2000  per  m

Typically I would use Douglas Fir for the frame, Larch cladding and wool insulation. I mostly do concrete piers or block foundations, this keeps use of concrete to a minimum, and makes for a versatile and affordable base.  Internal finish can be anything from plywood lining to skimmed plasterboard.

Here’s an idea of the costs for some items;

Foundations on a level and clear site could cost £750 to £1,000.

Electrical installation; getting power to the building, sockets and lighting could cost from £1000 to £1,750.

Plumbing and drainage;  getting water to and drainage from the building, fitting a toilet, basin and kitchen sink could cost between £2,000 to £3,000

Different cladding profiles can be specified and all are available in Larch, Chestnut, Cedar and Oak. Other options as mentioned could include kitchens and bathrooms, or you may want to consider a Green Roof as this adds insulation, can reduce water run off and increases biodiversity.

Overall price can vary widely with timber specified, quality of windows and doors, and customer input, see My Approach to get an idea of how you could also save costs and to understand the range of ways I work.
