Winchester Hobby Rooms

Hobby Rooms are for people looking for a sturdy garden shed, made from our outstanding quality materials. Using the same specifications as the workroom, the difference is the windows are smaller (still opening) and there is no overhang to the front gable end. The building is only available on a supply only basis.


75mm x 38mm Planed (Eased Edged) framing.

We use selected timber with a very high grade, which is subject to less twisting and warping, to provide a sound base to start from. Higher grade timber is slower grown to provide more strength.

FSC Timber

FSC is from certified Forest Stewardship Council forests, meaning the timber is sustainable (usually from Scandinavian Forests).

Tanalised Shiplap Cladding (125mm x 16mm)

The majority of our garden buildings are constructed with shiplap cladding. The cladding itself appears similar to tongue and groove, except the internal part of the groove is missing from the profile. The design behind our shiplap is it allows a certain amount of natural movement to take place throughout the change in seasons. In relation to this, we have developed our own profile of shiplap with a large overlap and tongue, which offers more protection to the building, thus increasing the lifespan. The cladding itself is tanalised (E-tanalith) to provide a rot resistant finish for over 25 years.

One advantage of shiplap is that it has a planed finish, and it also provides a near flat finish. This helps when fitting items such as hinges and door furniture.

By tanalising the timber with E-Tanalith, we are protecting against rot & decay for 25+ years.

Plywood & Paper Lining

Initially we used to paper line the buildings with the bitumen vapour barrier, to ensure the rainwater didn't soak into the building, however we found the paper will crinkle during the summer once it is dry. We therefore provide an additional skin of plywood to line the outside of the framing. In addition to the improved appearance, it provides extra rigidity and insulation, which is ideal for keeping your personal belongings dry.


2 x standard garage windows come as standard. You can choose from any of our standard doors and windows or if you have a particular size and design we can incorporate them into the building


900mm wide personal door You can choose from any of our standard doors and windows or if you have a particular size and design we can incorporate them into the building

Base Requirements

The customer is required to construct either a concrete base of 150mm compacted hardcore, and 100mm concrete, or heavy duty smooth paving slabs onto a sand and cement mix. Hardcore will be required under the paving slabs, with a membrane between the two.

If you intend to utilise an existing concrete or paving slab base, please ensure it is flat and level, as an uneven base makes it very difficult to stop the floor bouncing.

On some of the larger buildings a course of single engineering will be required to bolt down the building.

Should you require more information please follow this link or contact us for further details.

Roof Construction

Standard roofing is heavy duty 38kg Green Mineral Felt onto 12mm O.S.B. Boarding. The boarding is fitted onto purlins. We can provide alternative roof coverings.

The standard option of roof is O.S.B. (Sterling Board) with a heavy duty (38kg) green mineral felt covering. The life expectancy of this product is 6-8 years. This felt is included in the standard price for the buildings.

Should you wish to upgrade the roofing for cosmetic reasons or to increase the time between maintenance, we offer felt tiles, Cedar tiles, Onduline, Rollaclad metal roofs or Tapco Slate


The standard flooring on Workrooms & Leisure Rooms, is 22mm Tongue & Groove boarding onto 75 x 38 tanalised joists. This would be the standard flooring option for buildings up to 18ft x 12ft. The larger buildings that require a floor will have a 22mm (V313) chipboard flooring (loft boards) onto the same tanalised floor joists. In addition to this, a brickcourse will be required around the perimeter of the building, set to a plan that we send to you - on top of a concrete pad.

Farm Shops & Larger Workrooms will be constructed using 100mm x 38mm Planed (Eased Edged) framing.

Base Specification

The customer is required to construct a concrete base of 150mm compacted hardcore, and 100mm concrete. If laying a new base, we would recommend that a DPM (damp proof membrane) is laid between the two. If you have an existing base, it is not necesary to dig up and lay a membrane. Once the concrete is set, a single layer of bricks is required around the perimeter (set to a plan provided). We recommend that the concrete is larger all round (by 50mm) than the plan indicating the brick course.

The sections of the building sit on top of the brick course and are complete with a DPC (damp proof course). Our fitters will drill through the bottom rail of the building and into the concrete, and fix the building in place. The floor is then fitted inside the brick course with the flooring finishing level with the top of the brick course.
