Carports & Garages

"Classic Country" 

SolidLox’s Traditional Garage range is designed to facilitate easy construction while preserving a traditional aesthetic. We achieve this through the use of the Solidlox proprietary connective system, an improvement over older methods of construction, to connect our beams.

Special Levelling System

Our posts sit on adjustable metal baseplates, concealed by wooden shrouds, to ensure a perfectly level structure, while the addition of curved bracing with mortice and tenon joints to posts and your choice of timber and cladding finishes the garage in a style that speaks to you personally.

Individually Customised

The Solidlox system lends itself to customization. We build our timber garage kits in green oak, douglas fir or redwood and offer a range of options. You can choose your ideal roof covering, cladding and enhancements such as doors, insulation, windows and dormers.

Planning Compliant

With consent for planning permission in mind, we offer low pitched roofs that keep the overall height of the garage below 4 metres. We also offer high pitched roofs for those looking to create a room in the roof, ideal for storage or a home office area.

Bespoke Designs

We provide a full bespoke service along with our beautiful range of standard single, double and triple bay garages. If you can provide us with a rough, dimensioned sketch of what you want, we will return a quote for supply of the kit and for erection.

Higher Specifications

Solidlox timber garage kits are built to a higher specification than similar products. We use heavier beams (100mm x 220mm) and heavier posts (150mm x 150mm) to provide wider and deeper bays, and we install sarked roofs with waterproof membrane covering to create an enclosed, dry structure straight away.

Grand Garages

Extendable – Outwards AND Upwards

Grand Garages are designed to be extendable. The precision manufactured frames enable you to start with the smallest models and then, as and when the need arises, add to the structure, either at the end, the side, or by replacing the roof.

Made to Match in with YOUR present buildings and architecture.

Easy Timber Frame

Brilliant New Concept
