The Process

We’ve used our years of experience to make the process as simple for our customers as possible. Understanding you'd rather not deal with third parties in the process, we offer an all in one garden annex solution. Simply sit back and let us take care of the rest. Our vast experience of installing buildings for every use means we are well placed to help you along your journey.

Our Buildings

We take great pride in the design and build quality of your annex. All of our garden annexes are signed off by building control and come with a comprehensive 10-year guarantee. We have to meet the same insulation requirements as a new build house, so you can be sure your garden annex will keep you warm, whatever the weather outside.

Walls

Our external wall sections are based on the design of a modern timber framed house.

3mm Plaster Skim

Insulated plasterboard

A cavity for your wires and pipework

Timber frame mounted SIPs panel

Photonwrap Breather Membrane

Cavity Gap

17mm External cladding

External cladding is all treated with a fire-retardant coating.

We can install partition walls to create additional rooms in your annex. Our internal walls featuring sliding doors feature 4x2 studwork backed both sides with plasterboard. All other internal walls feature 3x2 studwork double lined with both a melamine panel and plasterboard.

Our external walls are clad as standard in FSC certified Norwegian redwood. We offer upgrades to a honey redwood and cedar, and slatted redwood and honey.

All walls are painted white as standard. If you would like your building painted a specific colour, just provide our painters with the paint colour of your choice and we will use this for you.

Foundations and Floor Panels

Our foundation system is a screw method. The suitability of this foundation type is assessed during your site survey where we will inspect your ground and check the length of screws required.

Once the foundations are laid, the team will install a 6mm steel plate attached to a screw which allows us to adjust levels. We use a laser level to ensure your plates are completely level before laying the floor panels.

Our floor panels are structurally insulated panels, featuring 100mm of insulation, sandwiched between powder coated steel. On top we lay an underlay and your choice of laminate flooring.

Roof

We use Kingspan structurally insulated panels on your roof. These 5-part panels feature a powder coating to the underside, a layer of steel and 120mm-151mm of insulation. Another layer of steel sits on top and an epoxy resin is applied to the surface to protect the steel. Our one-meter wide panels have a core thickness of 120mm and peak at 151mm at the ridge. We screw plasterboard to the underside of the panel which is plastered and painted ready for you to move in.

Doors and Windows

Our doors and windows are all made by Clear Edge. Clear Edge are one of the leading suppliers of garden room and residential doors and windows in the UK. All door and window locking mechanisms meet the latest insurance standards. Glazing u-values exceed UK building regulations and we install toughened glass in all units.

All buildings come with a 1.45 or 2.3m wide French door set as standard. We also include an opening rectangle and an opening lozenge window with every annex. We also offer a range of larger French doors, sliding doors and bi-fold doors as upgrade options. Every building must be installed with a low threshold French door to be signed off by building regulations. All habitable rooms (bathrooms and hallways are excluded) must have a either an opening door or a rectangle opening window as an escape route.

We also offer a range of picture and full height windows which are available to allow more light into your garden annex. Doors can be located on any front elevation and windows can be located on any elevation. Window location and size may be restricted on elevations built closer than one meter from your property boundary.

Kitchen

Our garden annexes come with a fully installed kitchen as standard. This includes an oven, induction hob, extractor hood and a sink with hot and cold water. We also include a fully integrated 70/30 Fridge/Freezer. You can upgrade to a 6-unit l-shaped configuration which adds a washer or dishwasher, or our 8-unit l-shaped design, which includes a microwave and both a washer and a dishwasher.
