Oak timber garages are stunning but can be expensive.  We can produce a range of oak styled timber garages for a fraction of the price, please do not hesitate to contact us for further information. The structure of the building is based on 100mm x 38mm Planed (Eased Edged) framing which provides a significant level of strength and rigidity.

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 that the timber is sustainable (usually from Scandinavian Forests).

Tanalised Shiplap Cladding (125mm x 16mm Nom)

The majority of our garages are constructed with ship-lap cladding. The cladding itself appears similar to tongue and groove, except the internal part of the groove is missing from the profile. The basis behind shiplap is it allows a certain amount of natural movement to take place throughout the change in seasons. In addition 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

We paper line the buildings with bitumen vapour barrier, to ensure the rainwater does soak into the building, however we found the paper crinkles during the summer once it is dry. We therefore provide an additional 4mm skin of plywood to line the outside of the framing which hides the vapor barrier and improves the overall internal appearance, the ply also provides additional rigidity and insulation, which is ideal for classic cars & bikes.

The Winchester Timber Framed Single Garages are supplied with two versions of garage door as follows:

Double Barn Doors, are ledged & braced fully framed double doors, treated in golden brown. They are complete with 2 front over-locking latches, and 3 pairs of hook & band hinges. Internally there is a drop bolt & pad bolt on the secondary door to secure it, whilst allowing the right-hand door to open. The standard door size is 2440mm wide x 2134mm high.


White, Brown, Black or Anthracite Grey Metal Up & Over Doors. – These are Hormann doors, complete with frame. The standard Up & Over door is a canopy design, however, should you require a motorised unit to be added, a fully retractable door will be required.

Should you wish to upgrade the standard doors, we offer the following options.

Cedar Double Doors. – These are the same size as the standard double doors; and are fully framed, and plywood lined. The front is constructed from Cedar tongue & groove, whilst the hinges are more ornate cup hinges (as opposed to hook & band hinges). The lever handle on the front controls two steel rods that locate in the ground and in the framing of the building to provide additional security. The secondary door features a pad bolt and a drop bolt.

Cedar Infill Up & Over Doors. – These are Hormann Up & Over doors, and feature cedar timber within a metal frame. Again, the standard is a canopy style door, however should you require a motorised unit to be added, a fully retractable door will be required.

Personal Door. – Standard personnel timber door matches our standard double doors, in that they are ledged & braced and treated golden brown. Complete with 3 hook and band hinges, a pad bolt, and a hasp & staple (you will need to supply a padlock). Should you require a framed personal door, the size would be 840mm wide, and it would have a lever lock with a brass handle.

There are other doors available, please refer to ‘Additional Optional Extras’ below.

Bolted to Base

The customer or is required to construct a concrete base (or this can be provided by Garden Retreat) 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 necessary to dig up and lay a membrane. Once the concrete is set, a single layer of slotted semi-engineering bricks are required around the perimeter (set to a plan provided by Garden Retreat). We recommend the concrete is larger all round (by 50mm) than the plan indicating the brick course.  This stops the concrete breaking out when the garage is bolted through the engineering brick course and then into the concrete base.

The sections of the garage sit on top of the brick course and are complete with a damp proof course. Our fitters will drill through the bottom rail of the building and into the concrete and fix the building in place.

If you require a quotation on the base or further information and advice please do not hesitate to contact us.

The standard roofing is a heavy duty 38kg Green Mineral Felt onto 12mm moisture resistant O.S.B. Boarding. The boarding is fitted onto 50mm x 125mm joists (purlins), spaced at 2′ centres. We can provide alternative roof coverings (please see options below). Should you require Onduline roof sheets – please note, we recommend sterling board underneath, because without the boarding it is liable to condensate during the winter.

Should you wish to upgrade the roofing for cosmetic reasons or to increase the time between maintenance, we offer the following options.

Coloured Polyester Felt – This is available in the same colours as our Felt Tiles (Brown & Grey) and has a life expectancy of about 15 years. Please note this is only available on buildings up to 7m in length.

Metal Profile Roofing. – This has a metal profile roof in black or anthracite grey and comes with a water proof under felt.

Black Onduline Roofing. – This has a corrugated profile and is compressed felt & bitumen, giving a life expectancy of 15 years. The standard colour is black, although other colours are available. Onduline has the benefit of offering a clear roof sheet to allow light, however we recommend sterling board is fitted on the roof before the Onduline to prevent condensation.

Felt Tile Roof. – These are sheets of felt that have a profile of 4 individual tiles within the sheet. They overlap each other and are staggered to provide a tiled effect roof. In addition to the tiles, underlay felt is laid over the boarding beforehand to provide a secondary skin. Angled tin and additional felt strips are fitted to the gables to prevent water ingress, thus providing a life expectancy of over 15 years.

Cedar tiles – These make a beautiful addition to any of our buildings, long lasting and they are set out on battening with under felt

Tapco Slate tiles. – These tiles have a life expectancy of 50 years and look fantastic as a lightweight replacement slate tile, follow the link to find out more about ‘Tapco Slate’

Tiled Roof Option. – Should you require a tiled roof for planning reasons, we would be able to provide and fit the roof trusses (at 600mm centres) with a 30 degree pitch. We clad the gable ends for you, and fit the trusses in place, however a local tiler will need to batten & tile the roof, plus fit the soffits & guttering.

For further details & prices, please contact us

We include guttering as standard in either brown or black to allow rainwater to be easily collected and re-used, along with the obvious protective benefits.

Electrics can be provided by Garden Retreat, if you require a quote please do not hesitate to contact us.

Price on Application

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.
