At Dunster House we have an extensive range of garden buildings, giving you a variety of different roof and floor options.

All Dunster House wooden garden buildings with floors come with pressure treated bearers included as standard. Putting the timber through this pressure treatment process means that the preservative is penetrated deep into the wood rather than it just being dipped or coated.

The building sits on top of these pressure treated floor bearers. This means that the part that’s in contact with the ground is protected from rot and insect infestation. All our pressure treated timbers come with a genuine 10 year guarantee (we suggest that a good quality water repellent is applied to the timber to help prolong its life). It’s shocking that some other companies provide untreated timbers, or don’t even include bearers as standard at all.

We see the floor as an integral part of an outdoor building. This is why we supply flooring with all our garden Log Cabins at no extra cost. You may notice that some others expect you to pay for this as an additional extra. Make sure to check exactly what is included in the price, with us there are no hidden surprises.

The floor and roof of our traditional Log Cabins are both made from thick 19mm interlocking tongue and groove boards. These give a sturdy and attractive finish to the interior. For better heat retention, we offer the option of adding floor and roof insulation to your Log Cabin (available at additional cost). We use 25mm thick insulation supplied in panels for quick and easy installation.

Garden Offices

Our Modern Garden Office ranges have been carefully designed with great attention to detail. This ensures we provide a high-quality and practical building with an easy-to-construct panel system, longevity and low maintenance.

Garden Offices

The 40mm thick floor is made up of an insulated sandwich panel that sits on the solid foundation of the pressure-treated floor bearers. At the bottom is a layer of Composite which provides a rigid base that acts as a barrier to moisture and is highly resistant to rot and decay. A layer of 25mm thick insulation is then held in place by a timber frame. This insulation helps to reduce heat loss through the floor of your home office and better maintain the temperature inside the room. On top is a Multi-Functional Panel (MR P5) board, giving a hard-wearing and moisture-resistant floor to your Garden Office.

At the top of our Shed range is 15mm thick pressure-treated tongue & groove floor and roof boards. These give an attractive finish, and the pressure treatment ensures they are long-lasting and low maintenance.
