How we build
Build Spec
Throughout the construction of hundreds of garden rooms in South East England, we have slowly tweaked and perfected our standard building specification. We strongly believe that our buildings are the best on the market, particularly when it comes to design aesthetics, construction materials used, and structural integrity.
The following build specification applies to the majority of our buildings.
Site Preparation: Clearing the Way for Your Garden Room
Before we can bring your dream garden room to life, the site needs to be cleared and levelled, ready for construction. Proper clearance of the area is the first and most important step in the preparation process, ensuring we have a clean, unobstructed space to work with.
Removing all obstacle such as trees, shrubs, old sheds, or garages ensures our team has a safe, accessible, and clutter-free area to carry out the installation efficiently.
We require a minimum clearance of 450mm between the edge of our buildings and any boundary fences or walls. This is to ensure we can access the side of the building to carry out construction work, but also so you have ample access the sides and rear of the building for maintenance purposes.
Need help preparing the area? We work with a network of local trusted landscapers who can assist with the preparation of the area and construction of a concrete base.
Is your garden on a slope? We can work with slopes, but recommend that these are levelled out as much as possible.
Groundworks and Base
We require a solid, level foundation to ensure the longevity and stability of the structure. A concrete base, reinforced with steel mesh, is essential to providing a secure, level platform for your building, preventing any potential issues down the line.
To make the process as seamless as possible, we work closely with a trusted network of professional landscapers who can prepare the site and lay the concrete base prior to installation.
On top of the concrete base, we then construct the timber base frame. This is constructed from 4×2 timbers, 75mm PIR insulation, and then a layer of chipboard flooring.
Walls
We construct our walls from both 100mm insulated steel panels and traditional 4×2 timber framing. We use the panels on the rear and sides of our building, and construct the front with 4×2 timber, that are filled with 75mm PIR insulation and then covered with OSB sheeting.
All ours walls feature internal cavities, achieved through battening, which allows for hidden services and added heat control.
Roof
We construct our roof with structural timber joists (120-150mm – depending on depth of the build and span required).
The joists are then covered with OSB sheeting, and then an EPDM rubber roof which offers a shelf life of 50 years and is becoming the most popular roofing system for extensions and garden buildings, given its durability and longevity.
External detailing
Our external detailing is where our buildings really stand out.
We use a combination of steel and plastic components to seal and finish our buildings.
We use three main types of external cladding; premium western red cedar cladding, composite slatted cladding, and anthracite steel. The cedar is beautiful and durable, and looks amazing next to contemporary steel, and the composite cladding looks amazing and is virtually no maintenance. We use the cedar or composite on the front elevation as standard (depending if you choose our Classic or Signature line).
Internal
We offer two finishing options for our garden office buildings: Full Installation and External Only.
With Full Installation, we also complete the entire interior—electrics, flooring and skirting, and plaster-boarding, plastering, and decorating—so your garden room is ready to use from day one.
The External Only option leaves the interior unfinished, giving you the freedom to personalise the space to your own style, timeline, and budget.
Signature Canopy and Decking
All Garden Office Buildings feature our signature 400mm canopy/decking feature. It’s equal to three decking boards wide, and provides a beautiful finish to the front of your garden room
For full installations, we include downlights in the canopy soffit.
Side Screens
On the front corners of our buildings, you have the option for an Open end, or a Closed end that featured a side screen.
Doors & Windows
Our buildings come with full height uPVC sliding patio doors as standard, 2.4m wide.
We also offer full height side windows in two widths, and also a slot opening window.
All our windows and doors are smooth grey on the outside and white on the inside, and we use 4mm toughened glass.
Electrical Features
As the primary use of our buildings are for office space, we use LED panel lights in all our buildings. They provide an incredible source of white light which is used in all modern office spaces across the world. We also offer standard downlighting.
For external lights, we use up/down wall lights as standard, with the option to upgrade to soffit downlight.
Each building comes with 4x double sockets and its own consumer unit. We also include an ethernet port for easy connectivity via a CAT 6 cable.
In terms of heating, we offer a contemporary electrical wall panel heater in white. As our buildings our so well insulated, these wall panel heaters provide the perfect heating option for your garden building.
