The Superframe

Our super strong timber frame building is perfect for a home office or workshop with substantial light through the double doors and front windows giving a contemporary feel. The extra deep studwork can accommodate retro fitting of internal insulation, electrics or cladding to personalise the building to your own taste and style.

The internal  height is approx 86 inches/2.18 m across the all unit. The roof design has no slope internally – it creates a ‘flat ceiling’ effect. The external height is approx 97 inches/ 2.47 m at the front of the building sloping by about 2 inches /45 mm. The roof cover is EPDM rubber that comes with extended warranty.

To enhance the longevity for garden building, every Superframe is fitted with a damp-proof rubber membrane that sits between the 18 mm heavy duty plywood flooring and 3”x 2” tanalised floor runners.

Our triple laminated doors are fitted with rubber seals, as well as solid timber windows, to further enhance weather resistance. There are two opening windows on any size building, secured with a casement stay and lockable handle.

All our buildings are manufactured in our own Essex workshops and constructed with slow-grown Scandinavian high-quality redwood timber. Prices shown are fully inclusive of VAT, delivery and installation.

Please note: The Superframe comes treated in light brown wood preservative as standard.

At a later date, you can personalise your building to your own taste by using a range of different preservatives, timber stain options or paint finishes.

The Superframe 18 ft in length (front) requires a partition wall front to back (this is included in the price)

The Superframe Summerhouse Base Guidance

Before purchasing The Superframe Summerhouse, it is important that you have prepared your base. Below you can find our PDF document on Base Preparation Guidelines for Summerhouses.


Reasons To Buy A Carr Summerhouse

We use high-grade Scandinavian redwood in the manufacturing process. Our timber is carefully picked for quality and the best part is, that it is sustainable. The timber itself is rated at source and then reassessed and selected for quality at our state-of-the-art sawmill. There are a lot of garden buildings available that were built with cheaper, quicker-growing woods that might twist or decay rapidly. We frequently run into people who have been using our Carr Garden Buildings for 20 to 25 years; the wood is still in excellent condition. We can also custom-make bespoke garden buildings to meet your specific requirements. Get in touch with us immediately to talk about your log cabin ambitions and let us make them come true.
