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

The standard Arched Roof Garden Office is supplied with one set of 1500mm uPVC French doors, two 600mm sided lights (full length) and a  600mm x 900mm  uPVC casement window, further windows can be added if required and are listed in the ‘Additional Options’ section below.

The Arched Roof Garden Office is manufactured with a beautiful arched roof which comes under the 2.5m roof height. In addition to this the building comes with 3 double sockets, spot lights, a consumer unit and switch. There are also a number of additional electrical options to add to the building if required.

The Arched Roof 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 12mm x 100mm Cedar cladding on the exterior, providing you with a 25 year plus 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 15mm 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.

Arched Curved Roof
The Arched Curved 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.

The Arched Curved Roof comes with a heavy duty polyester felt and large overhangs, 500mm to the sides and a 700mm overhang to the front which covers a decked area.

The Arched Roof Garden Office and Garden Room does not come with guttering as standard, that is why the side overhangs are 500mm to keep the rain away from the side walls.  If you do want guttering we can provide this at an additional cost.

The guttering and down pipes are supplied in either black or brown.

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.

All our buildings included delivery and installation although please contact us for delivery prices if you are located in Cornwall or Scotland.

All our buildings are installed buy our fully trained crews who have many years of experience.

Our installation crews will require clear access free from obstacles, trees, vegetation, overhead cables from the delivery vehicle to the site where the building will be erected.

They will also require 400mm clearance around the building to allow your building to be erected safely with clearance suitable for ladders and steps. If there is less than 400mm please contact us to discuss the options.

Sections can be as large as 3.0m x 2.4m hence we will need to know of any obstacles, bends or height restrictions before manufacture takes place.

Delivery & installation takes place on the same day via a 7.5 tonnes lorry – 28 feet long x 8ft wide.

A majority of buildings are installed within a single day, however larger garden offices, triple garages and commercial units will require more days on site. We will indicate the estimated assembly time at the time of order.

We will require a postcode for the site address and sufficient parking on the day of delivery to allow the installation crew to park as close to the site as possible.

Should your site be further than 30m from the parking location, please contact us prior to manufacture to ensure that we can deliver and install safely.

Please note that on some occasions we can take sections of buildings through the house but there is a surcharge to do so as the sections need to be made smaller and we require more staff on site to carry the sections through the house.

If you have any questions or queries concerning delivery and installation please do not hesitate to contact us.
