The Lyndhurst Composite Garden Office and Garden Room is a garden building requiring ZERO maintenance, it never needs painting or treating, just a light rinse with a hose to remove any residual dirt, it doesn’t get any easier than that!

They come in 6 sizes with a range of standard window and door options including French doors, bi-fold doors and sliding doors. Please also note we can also provide bespoke sizes and additional window and door combinations.

The Lyndhurst Composite Garden Office and Garden Room is supplied as an easy ‘self-install’ building and comes with full instructions and all parts are clearly marked, we do however recommend the erector is a competent ‘DIYer’.

The design of the building allows the ‘customer’ to install the electrics to suit your needs, insulate and board with any material you choose and with a range of composite cladding colours and window colours you can tailor the building to suit your exact requirements.  We can also supply a roof lantern as part of the design which looks fantastic.

The structure is manufactured with pressure treated 75mm x 50mm timbers throughout, with a breathable membrane, 25mm external air gap with the composite cladding attached to external battens.

To ensure the cladding is secure and watertight on the connections we install high performance powder coated corner, end and butt joint trims to guarantee high strength and waterproof joints with no distortion, cracking or warping. They also come in matching colours to suit the cladding colour range.

The composite wood grained external cladding does not contain wood fibres or organic materials so just by its very nature is resistant to rot, decay, and attack by insects. It will not absorb moisture, expand or contract and ultimately will not split or crack.

With excellent wind and hail impact resistance the wood-grain embossed matt finished boards and aluminium powder coated trims provide an extremely high quality product.

Finally, the Lyndhurst Garden Office and Garden Room windows and doors are extremely secure with steel reinforced profiles, multi-lock doors and a ridged construction. Overall your garden building will ensure the contents will be safe and secure.

The contemporary roof is popular when you want a building that is not too obtrusive in the garden. The overall height is 2.5m therefore sits within the permitted development rules but it is always worth checking with your local planning authority.

The rubber membrane supplied is bonded to the roof using the adhesive supplied and the edges are trimmed with the edging trims and corners provided. It is extremely easy to apply and comes as part of the self-install kit.

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

We do not supply an electrics pack due to the large range of electrical choices and as the building is not supplied pre insulated you would a require first and second fix installation with your choice of fittings.  In addition to this the electrical installation will have to be certified by a suitable qualified electrician.

If however we are providing a turn key installation we would be happy to install the electrics.

    We changed the design during the process, and they discussed the details and continued to adjust their quote, to ensure that the correct specification was being provided for the building’s needs.

  • “We chose Garden Retreat to install a stand-alone custom garage build in the summer of 2020. Having researched various local options we decided to use James and his team because of the customisable choices with the size of the building, and the different finishes available. We chose the cedar door and roof options with a feathered-edge cladding and the end result is great. From the start of the project right through to the end there was no delay in communications and answers to the many questions we had were answered promptly. The building itself went up very quickly and we are pleased with the quality and sturdiness of the garage. Thanks again and we have already recommended the team to friends and family.” Verified Review By Houzz

    Ms S– London SW6 – 2.6m x 4.8m Contemporary Garden Office – 2.5m Maximum Height
  • “Being a thorough sort of person I researched a number of options for my 20ft x 12ft timber garage and went into great detail, creating spreadsheets and detailing the pros and cons.

    I knew I wanted a quality product and I wanted to have tanalised timber which narrowed the field too.  I was also concerned about the point at which any wood might be sitting in water on the base.

    Garden Retreat ticked all the boxes, the garage sits on 1 course of bricks and the cladding stops short of the base, so even if water does stand on the base it won’t make contact with the wood.  Additionally, Garden Retreat ply line their garage for extra strength and security.  In the end, the choice was easy, only Garden Retreat met all my criteria and they were a pleasure to deal with from pre-order to delivery. The erection was on time, quick and fuss-free and the finished product looks fantastic. Highly recommended supplier!” Verified Review By Houzz

    James spent a lot of time working with us to ensure all the elements were designed into the building and had a large number of examples of previous projects which demonstrated their ability to provide us with the garden office and store we wanted.

    Finally they worked very well with our garden designers, the installers were polite and cleared up after the timber building had been installed.

  • “We sought a non standard design and build to our outline spec for a 10m x 6m garage to be used for classic car storage. We awarded the contract to Garden Retreat in part because of the advice on materials and construction offered by their James Parker. From design through planning approval to construction took 3 months. Erection of the sectional garage took 3 hours (excluding tiling). Brilliant to watch. Price quoted was the price paid. No hidden extras. Well worth taking the elevation drawings to aid planning. Very satisfied with the finished product. Thank you.” Verified Review By Houzz

It was a long journey from design through planning permission and a large amount of ground work to be done before the base could be laid and throughout James Parker remained helpful and available, if needed, with experienced advice. An unexpected but necessary alteration the week before the building was due to arrive was imaginatively  and speedily resolved. The build itself took just two days and I was delighted by the finish inside and the quality of the work. I’m really, really pleased, and the studio is a lovely place to work.” Verified Review By Houzz

We are delighted with it! The customer service was also truly bespoke. James came to visit us several times throughout the process and was very responsive via telephone and e-mail at any time. He provided really practical, common sense advice and we never felt we were being sold anything at all. The building is beautiful – the bespoke design means it fits perfectly in our space and feels like it has been there for years!
