Construction Methods
We craft our structures using top-grade materials, predominantly sourced from British suppliers. Through years of experience, expert craftsmanship, and superior material selection, we’ve perfected a construction methodology that truly distinguishes our garden rooms in the marketplace.
Quality-Built Using Premium UK Materials
Our expertise, craftsmanship, and premium materials have helped us create an exceptional building process that sets new standards in garden room construction. Below you’ll find our standard build specifications that apply to most projects.
Walls
We construct our walls from both 100mm insulated panels and traditional timber framing 4×2 timbers filled by PIR insulation, convered by a sheet of OSB for stability.
All ours walls feature internal and external cavities, achieved trhough battening, which allows for hidden service and added heat control.
Floor
Like the walls, we use traditional timber construction. This is usually 5×2 timbers (120mm thick) with insulation in between.
The entire floor will sit completely clear of the ground in order to allow air to circulate underneath. We also use a membrane that sits on the underseide of our to provide protection aginst moisture.
Expand your living space effortlessly with our hassle-free annexe solutions. We handle every detail, from design to construction, ensuring regulatory compliance and superior quality. Create a comfortable, independent living area that brings your family closer together.
Roof
We construct our roof with timber (120-150mm) and EPDM, or insulated panels (80-120mm), depending on how bespoke the building is.
The timber method involves an EPDM rubber roof offers a shelf for extensions and garden buildings, given its durability and longevity.
For our standardised builds, we have adopted the use of insulated roof panels. These are very durable, provide great insulation, and can be installed much faster than traditional timber roofs, meaning we are on site for less time.
External
We use two main types of external cladding; premium western red cedar cladding and anthracite steel sheets. The cedar is beatiful and durable, and looks amazing next to contemporary steel. We use the cedar on the front elevation as standard, and can also add it to the sides of the building if required.
We use a combination of steel and uPVC finishes too, including steel covers for each corner of the building. We belive that steel is superior to uPVC in these areas and will add many years to the life of your bulding.
Internal
Your bulding will be plasterboard, fully plastered, and painted. This is the method used in new homes where plasterboard is used, achieving the same look as plastering.
We use a laminate oak flooring that comes in two styles, sitting within a modern skirting board.
Doors & Windows
Our buldings come with full height uPVC sliding patio doors as standard, 2.6m or 2.0m wide depending on the size of your building.
We also offer full height side windows in two widhts, and also slot opening window.
All our windos and doors are smooth grey on the outside and white on the inside, and we use 4mm toughened glass.
Decking, Overhang & Side Screen
Our standard buldings feature a 400m decking area, roof overhang and side screen. We belive that these features are essential to protecting the front of your building from the elements. Ther also provide necessary shelter when entering or leaving your office building
- Roof overhang prototects your building
- Maintenance free composite decking
- Ontemporary side screen
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 xternal 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 eacy 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.
Groundworks
We generally use ground piles for grass surfaces or ground pedestals for concrete surfaces. We belive these are the simplest and most affordable way to achieve a level building, raised off the ground, that will be protected from moisture and humidity.
