Our garden rooms are built on a reinforced concrete foundation. We believe this is the best method to build a permanent garden room, you wouldn’t build a house or a rear extension on anything other than a strip foundation and concrete slab, so why compromise with your new garden room building.
We protect your garden by laying trench covers before we start the ground works.
What are the advantages of a concrete base :-
- A reduced dig creates an internal floor to ceiling height of 2.15 metres
- There is no void under the building avoiding nesting rats and foxes
- No decking is required outside the room to cover the void area, so if you wish you can step straight from your garden room onto the lawn, this saves you the additional expense of decking and avoids ongoing maintenance of the skirting around the building and the decked area.
- As there are no pockets of cold air under the building there is less heat loss.
- A great solution for a site on a steep gradient.
- A concrete base, we believe this is the best form of construction for a permanent building.
- Reinforcing the foundation with rebar has a high compressive strength.
- Great for rooms which require a stable base ie. gym, weight training, dance studio – a concrete base avoids the bouncy floor effect.
You will never see decking around an Executive Garden Room, our rooms are 100mm above ground level so you can step directly out onto grass, paving or stone. Why pay extra for decking when it has a short life span and becomes an ice rink in the winter.
On top of the concrete slab, we lay a further damp proof membrane and 100mm of insulation, moisture resistant chipboard and finished with your choice of flooring.
We offer a variety of choices of flooring, engineered wood flooring, tiles or laminate.
Clad in Cedral Weatherboard with its ‘A2-S1,do’ rating for fire and its painted finish which will not fade, it is a practical, maintenance free, contemporary product which comes in various colours.
Fire safety is extremely important, especially if the building is to be used for sleeping accommodation.
The walls are 200mm thick and contain a total of 140mm insulation and sheathed in 18mm OSB (3) structural board, we use a warm frame construction method in which 50mm of the insulation is on the outside of the building, this ensures that the timber frame remains within the warm envelope. This also offers higher thermal mass and excellent heat retention.
We only use treated CLS timber which has been structurally graded and pressure impregnated with Tanalith E treatment for external use.
We offer the highest specification wall make up in the garden room industry.
Resilient bar is included allowing the ceiling to be de-coupled from the vibrating surface which will reduce both vibration and impact noise penetration to substantially improve the sound insulating qualities, this is ideal for a music room or recording studio.
The walls are then finished internally with 12.5mm plasterboard which is plastered and painted with 3 coats of vinyl matt paint, this created a contemporary feel with no ugly cover strips on show.
Our roofs are based on a flat roof design, they are built with a warm deck construction.
As we build our rooms from scratch on site using a substantial traditional timber frame system, our structure can take the weight of a 3-layer torch-on bitumen roof system. We are one of only a few garden room suppliers who use this long-established roofing covering system.
The roof is finished with 3 layers of torch on mineral felt totalling 8mm thick.
The roof structure contains a total of 100mm PIR insulation board, 18mm OSB (3) structural board, 12.5mm plasterboard which is plastered and painted with 3 coats of vinyl matt paint.
All our flat roofs have a 17mm per metre fall to comply with Building Regulations.
We can install various sizes of Velux Roof Lights, these can be fixed or opening, controlled by remote and include rain sensors, blinds can also be fitted within the unit, especially useful if the garden room is to be used for sleeping accommodation.
We install guttering to the back of your garden room to a single downpipe to a water butt.
The roof has a 10 year guarantee, although will last a minimum of 30 years.
Sedum roofs can be installed, for them to have longevity they need to be installed correctly.

Each element in the construction such as the plasterboard, insulation, and cladding has a u-value.
The lower the number, the more efficient.
