Wooden/Timber Garages & Doors


The Trentan range of timber Heavy Double Timber Duty Garages are produced using high quality pressure treated redwood deal timber on a more than substantial framework which is 90 x 38mm (3¾” x 1¾”) as standard. The roofs are made from the highly rated Onduline roofing on top of 8mm OSB boarding. This gives an unique 15 years guarantee to the garage roof giving you long term peace of mind. You can expect a very long life for your heavy duty timber garage and the warrented life span using Tanalith pressure treated timber is 15 years plus.

Tanalised Timber & Onduline Roofing – 15 year Guarantee – saving you time!

With a range of standard sizes, from 8½ x 14′ up to 20′ x 30′ and the option to make changes to the standard timber heavy duty garages you can be assured these garages will meet your long term needs. These buildings can be made to your size and the doors and windows can be positioned to suit.

Timber Buildings Display Site in Staffordshire and Surrey for your Viewing.

We don’t have this garage on display in Surrey but do in Staffordshire, but in Surrey we do have the Heavy Duty Workshop for you to examine for quality and construction of our buildings at our display site. The garage is essentially the same except the garage does not have a floor, it’s taller and has heavier framing. We believe that you should be able to view the quality of our buildings and not just rely on a brochure or computer screen – UNLIKE most of the competitors who DON’T give you the opportunity to view at all.

Our background in timber building manufacturing, starting in 1979, gives us the know how about the quality of materials which should be used. Our Ethos is ‘Make to a Standard – NOT down to a price’.
