The Winchester Traditional Garden Offices and Garden Rooms


The Winchester range of garden offices are based on a modular design in sections of 1200mm and 600mm by 2134mm high  There are a range of standard buildings which have a number of windows and doors and you can decide where you want to position them during the ordering process.

The Traditional Garden Office is supplied with a single half double glazed traditional door and double glazed traditional windows, the number of which depends on the size of the building. Additional windows can be added if required.

The Traditional Garden Office can be either manufactured with a pitched roof or a mono roof which comes under the 2.5m height. In addition to this the buildings come with sockets, lights, consumer unit and switch.  There are also a number of additional options to add to the building if required.

If the standard sizes are not suitable we can manufacture the offices to suit the size you require. If you have any queries please do not hesitate to contact us or have a look at our Bespoke Range.

The Traditional Garden Offices or Garden Rooms are constructed using 1 1/2" x 3" (38mm x 75mm) selected framing. The framework is built and clad with 16mm x 125mm tanalised shiplap cladding on the exterior, providing you with a 25 year rot resistant finish. 

The interior is lined with 12mm brush grooved plywood, to provide a high quality and attractive finish, with cavity filled 50mm polystyrene insulation. Skirting and appropriate moldings are also fitted to provide a professional finish.

The floor has a 12mm plywood finish, and sits onto 1 1/2" x 3" (38mm x 75mm) tanalised floor joists with 75mm Celotex insulation underneath the plywood. A second level of tanalised bearers lifts the floor away from the concrete base to provide the necessary air flow beneath the building.

Roof Construction

The Traditional Garden Office roof construction comes in two versions although with the Traditional version the pitched version is the normal choice.

Pitched Roof

The pitched roof version is specially designed to provide maximum head room, with a clear span between each gable end wall. The inside of the roof is lined with 9mm plywood, and the outside of the roof has 12mm sterling board and 50mm polystyrene insulation fills the cavity.

Felt tiles are also fitted to the pitched roof of the office on top of an underlay felt to provide both a long lifespan and an attractive finish. The felt tiles are available in either Red/Brown (Clay effect) or Slate Grey.

The pitched roof ridge height, depending on the building size, is between 2.8m and 3.2m high as an average height.  On smaller buildings we can drop the ridge height down to accommodate a 2.5m maximum height which will satisfy UK planning rules.  If you need further advice on planning please call us for advice, or click here planning portal.

Mono Roof

The Mono roof is popular when you want a contemporary look or you are looking for a garden building that is not too obtrusive in the garden

Alternatively, we normally specify the mono roof if you are trying to stay below the 2.5m high planning rule if you are within two metres of your boundary,

The Mono roof comes with either brown or grey polyester felt and now we can offer a metal clad roof for an extended service life.  The Mono roof comes with a standard 400mm overhang to the front and 150mm to the sides.


Guttering is supplied and fitted as standard to the front & back of the pitched roof. Please note the roof overhangs the walls of the buildings by 6" (150mm) at the gable ends, and 1' (300mm) to the front and the back - this is in addition to the size of the building. We can however adjust the overhang sizes in the event of space restrictions.

The mono roof design has guttering to the rear only, or to just one side depending on the slope of the roof.  The guttering in this instance is hidden by using barge boards.


The lights, sockets, and wiring are all in place ready to be connected by a qualified electrician. Standard offices are complete with a consumer unit (with breakers), a light switch, lights (with bulbs & transformers), and sockets, although more can be purchased to suit your requirements.

Please note that all sockets and lights will need a qualified electrician to connect the wiring at both the consumer unit end, and the socket / light end to comply with the current regulations. In addition to this your electrician will also need to connect the electric feed from the external power source to your office.
