What this means:
Thermo Treated Radiata Pine Weatherboard
Five times more expensive than untreated redwood pine, this superior weather-resistant wood cladding is thermo-treated to remove moisture, resulting in a solid exterior resistant to both movement and mould.
Breather Cavity
You can breathe easily because your Radiata Garden Room’s walls breathe too. The R&D Team here at Gillies & Mackay have devised the perfect patent-pending slimline solution to protect your Radiata walls from moisture build-up and ensure that they’re properly ventilated.
Insulation Board
Insulated walls give you heat retention in winter and prevent overheating in summer, allowing you to save on energy costs.
V'd Lining
To finish off your Garden Room, the internal walls are lined with redwood cladding. With a straight flush finish and V-shaped joins, this provides a touch of class and sophistication – the G&M way.
Engineered elegance
for your garden
These models are all under 12m2 which gives us the ability to create an all-new simplified specification, giving you all the versatility of a large garden room without the price tag.
Please Note: This specification is not available above 12m2, although Radiata cladding is available as an upgrade on any G&M building, if you like.

Within permitted development

Assuming all location factors are adhered to, all four designs meet permitted development requirements.
Suitable all year round
Fully lined and insulated, four-layer construction keeps you warm and dry in the winter and cool in the summer.
No concrete plinth required
Thanks to the simplified under-12m2 design, only a level slabbed area or ground screws are required.
Eco-friendly
Made with recyclable and sustainable materials, and all suppliers are certified.

    Premium Aluminium double glazing
    Slimline & Superior

    Choose your design

    Choose from four time-tested designs in the perfect size and shape to add style to your garden.

    The Rannoch immortalises the traditional apex roof while The Vorlich preserves the classic pent roof design. Both are topped with steel box profile roofing which carries a 20-year guarantee.

    For a contemporary update, The Kindrogan shows off a pyramidal pitched roof, and The Deuchny boasts a pentagonal pitched roof.

    These buildings feature Isola shingle roofing that’s guaranteed for 30 years. Isola shingles are a sustainable market-leading product from Norway only available in the UK through G&M.

    Ground works & Extras

    The Garden Rooms (under 12m2) require either a full slabbed area or a ground screw base. Both are priced as an estimate and are subject to site visit.

    We advise that all basework be constructed with a soakaway to draw any run-off water away from the building. Guttering will also further increase the longevity of your Radiata Garden Room. We offer this as an additional option, or you can tackle this yourself.

    Guttering
    Image

    The Radiata Garden Rooms (under 12m2) do not come with Guttering as standard. We advise that all basework be constructed with a soakaway in mind to allow the water to run off the roof and be drawn away from the building.

    It would be advisable for 10' x 10' & 12' x 10' sizes to opt for guttering given the amount of water shed.
