Helena Garden Office - Left W4.3m x D2.7m

Our Helena Garden Office is the ideal workplace. High-quality roofing, uniquely-designed insulated walls, as well as 28mm double-glazed, sealed-unit uPVC windows and patio doors as standard, combine to give lower heating costs and a great workspace with excellent natural light.

The Helena’s inner walls are fire-resistant for peace of mind, and the floor, walls and vented windows are all designed to resist moisture buildup, making sure that the office remains a pleasant place to work at all times of the year. This attractive garden room is made of slow-grown Spruce, which is pressure treated against rot and insect infestation, so it can be enjoyed for years to come. The patio doors and windows have 4mm toughened glass as standard, to withstand stray footballs, while the multipoint locking on both windows and patio doors keep it property safe and sound.

28mm double glazing

We don't compromise on quality just because it's a garden building. Our garden offices have domestic style uPVC windows and doors, making your garden office secure and highly insulated. The 28mm sealed double glazing provides improved heat and sound insulation.

Multipoint locking Windows & Doors

Our garden offices come with domestic grade multipoint locking windows and doors. Great for securing your garden building and its contents! Euro cylinder locks are used in our uPVC doors to ensure maximum safety and security.

Fixings Included

We include all of the screws, nails and fixings needed to put the garden building together, so there is no need to worry about the type of screws, or length of nails. Everything is in the pack.

Fully pressure treated

Our Garden Offices are made using non-toxic, pressure treated timber. This process forces wood preservative deep into the pre-cut timber using a large pressure treatment vat.This means that you don't need to spend your time treating the timber yourself, or for the next ten years. The timber is treated against fungal decay and insect infestation without any need for the customer to apply treatment during this time.

Tall Door Height

With a walkthrough height of over 6'4" (1.94m) there is no need to duck on the way in. They are probably the tallest doors on the market and great for moving furniture in and out of the office.

Sliding Doors

Why waste precious space with a hinged door? Our doors slide smoothly open and come complete with locking handles, multi-point locking system, Euro cylinder locks and internal beading, for added security. And at over 2'2" (66cm) wide our doors give plenty of space for people and by temporarily removing the stops and handle (4 screws) it is possible to get them up to 2'7" (80cm) wide to cope with the bulkiest furniture.

IzoPanel Roof

Our Garden Offices feature a very advanced roofing system manufactured by Izopanel. They use a stiff polyurethane foam core (a material that provides a very low thermal conductivity rating) joined together tightly with overlapping cladding in a trapezoidal profile which makes strong joints that prevent water ingress. Altogether the roof is waterproof, has great thermal characteristics and is uniquely strong.

Moisture-Resistant Walls And Floor

Our unique design hinders moisture buildup inside the office. The walls of our Garden Offices have layers of shiplap cladding, moisture resistant membrane, thermal insulation panels and interior walls of Gypsum Fibreboard, which is also fire-resistant. The pressure -treated floor bearers are covered by a layer of Wood Plastic Composite, followed by layers of insulation and MFP fibreboard. These layers minimize the transfer of moisture through the floor and walls, making this garden office a comfortable working environment all year round.

Fire-Resistant Inner Wall

The inner walls of our Garden Offices are made using a fire-resistant fibreboard – a hard-wearing made from recycled paper fibres and Gypsum (Hydrous Calcium Sulphate). This Garden Office has increased protection from fire. The fibreboard comes unpainted, but you can decorate, as it is a good surface for paint and is easy to wallpaper.

15mm Shiplap Cladding

Shiplap cladding is named after the old boatmaking technique where the boards overlap. This means that the natural timber can expand and contract with the seasons and not create gaps. The curve or channel of shiplap cladding enables water to run off easily.

Energy Saving Insulation

The walls, floor and roof of our garden offices are all insulated to lower energy costs. We use Polyurethane to insulate our garden offices, which is proven to retain heat better than cheaper alternatives such as polystyrene or rockwool. The U values of our insulation are as follows: 0.64 W/m2 K in the roof, 0.62 W/m2 K in walls, and 0.70 W/m2 K in the floor.*Insulation means a reduction in loss of heat from an area that has been heated to a different temperature. If no heat has been applied, the insulation will be nominally the same as the outside temperature.
