    Collapsible content


    All our buildings are pressure treated which carries a 10 year guarantee against wood rot or insect infestation. Although all our timber is tanalised, the building will still require 1-2 coats of a sufficient oil based water repellent. We advise this is carried out as soon as possible after installation and annually there after.

    Timber Base

    Don’t have a suitable base for your building? We offer the option to add an additional timber base for a fraction of the cost of concrete bases. Opting for a timber base with your building will take away the hassle and added expense of having a base laid. Our professional fitting teams will take care of everything. Our timber bases are fully tanalised and carry a 10 year anti rot guarantee.

    Heavy Duty Poly Felt

    All our buildings come with green mineral felt as standard. As felt is a natural and perishable material we do not guarantee the longevity of standard felt. We offer the option to upgrade to our heavy duty poly felt. This carries a 12 month warranty for a small additional cost.

    Which Cladding Should I Choose?

    Shiplap is a tongue and groove cladding, where a panel is created from planks of interlocking wood.Log lap

    Loglap is again a tongue and groove cladding which has a slightly curved finish where the tongue meets the groove and is thicker than shiplap.
