All of our buildings come with a foundation system that uses a concrete sub frame that sits on top of concrete pad or pile foundations, or In some cases a pile and bracket system fitted directly to the floor frame (the type of foundation can vary depending on site conditions.) in some cases we may even use a dry system replacing concrete pads with large deep plastic crates filled with stone, this method provides more than adequate strength as well as further reducing our carbon footprint.
We believe the foundations to be one of the most important factors of the buildings structural integrity and longevity. Using these methods prevents any rising damp while being incredibly strong and durable and effectively transfers the weight of the building to the ground. These methods also allow surface water to drain naturally and causes minimal disturbance to any surrounding tree roots using a significantly less amount of concrete than a traditional poured slab. Also for whatever reason you decide to move or remove the building, the foundations are easily covered over.
Our floor has a 6 layer build up comprising of…
- Flooring material laminate or luxury vinyl tiles.
- flooring under lay
- 22mm industrial grade moisture resistant tongue and groove floor board
- C16-C24 graded treated timber 150mm
- 140mm rockwool or similar insulation
- Breathable damp proof layer
We use timber frame methods using 4×2″ timbers for walls on our smaller models and 5×2″
timbers on larger models. 6×2″ timbers for floors and roofs and unlike most other suppliers
all of our rooms are fully wrapped in an osb board to provide much better strength to the
overall structure, while also providing much better air tightness of the building.
Wall thicknesses are a minimum of 160mm 6.2” up to 220mm 8.6”
Our walls have a 9 layer build up comprised of….
- average 20mm cladding material.
- 25mm-50mm treated batten to allow ventilation.
- breather membrane that keeps moisture out and allows building to breathe.
- 9mm moisture resistant OSB sheathing for strength rigidity and airtightness.
- C16-24 graded treated timber 100mm-125mm.
- 100mm rockwool or similar insulation.
- Vapour barrier to keep moisture out of the structure.
- 12.5mm plasterboard.
- Plastered finish.
An extra layer of 25mm Celotex or similar insulation is added to the platinum package to give
a whopping 10 layer system.
We try to use a stable cladding material that not only looks stunning but doesn’t require a lot of maintenance.
Options include thermowood, wood fibre boards, or the very beautiful and very popular western red cedar.
We like to use a vertical cladding for a seamless modern but natural look.
The cladding materials we use do not require a treatment to prevent decay as they already have natural defenses against rot, or have already been through a treatment process. However like any natural timbers they will grey in colour over time, so If you would like it to stay looking new, an annual or biannual treatment of uv protection is required.
With the advancement of composite cladding in recent years, it is now possible to achieve the natural look with wood fibre board which can also be an option if you are looking for something with zero maintenance.
Thermowood is our lowest cost silver package standard cladding material which is very stable and pleasing to the eye but does require some maintenance to keep it looking fresh. We use a channel groove profile with a hidden fixing system to give a flawless and modern look.
Wood fibre board is our mid range gold package standard cladding material and is a combination of recycled wood and plastic. It offers no need for maintenance at all other than a pressure wash to keep it looking fresh. It still looks and feels like real wood but without the upkeep. Not to mention being extremely environmentally friendly and sustainable.
Decking in this material is also available.
Cedar is our highest range platinum package standard of cladding material that gives the most beautiful appearance with stunning natural pinks and browns. It is an extremely stable material but it requires a little maintenance just to keep it from turning grey over time if this is not your desired look. We use the very best cedar you can buy, rated at no2 clear and better with 15% no4 grade, using a profile with a channel groove and hidden fixing system to give a flawless and modern look.
Our buildings have a strong timber roof construction. Using either 6×2 or 6×3 timbers depending on spans. Properly ventilated at each end to allow warm air to circulate and escape, avoiding damp issues in years to come, all covered in 18mm thick OSB and an epdm rubber roof material that has a 50 year life expectancy.
Finished off with either upvc or aluminium trim in black or grey, and black plastic guttering.
We use firing strips where possible to achieve our fall so the internal ceiling will remain flat at one level so you don’t lose head height at the back end of the build.
Our roof system has a 9 layer build up comprising of…
- EPDM rubber with a 25 year manufacturer guarantee.
- 18mm moisture resistant OSB board.
- firing timbers to create fall for rainwater.
- ventilation void.
- C16-24 grade treated timber 150mm.
- 140mm rockwool or similar insulation.
- Vapour barrier.
- 12.5mm plasterboard.
- plastered finish.
All of our builds are lined with 12.5mm plasterboard and professionally plastered ready for decoration. Internal walls can also be added if needed for an extra price.
We offer quality laminate flooring or luxury vinyl tiles in a choice of styles and colours.
Complete with skirting boards and are also complete with architraves if needed, making the inside of your new garden room feel no different to that of a brand new house.
DOORS AND WINDOWS
We use quality pvc or aluminum windows and doors, all fitted with planitherm argon gas filled double glazing units and insurance approved security locks.
We love the modern look of the anthracite grey but there are a range of other colors available.
And as an added bonus all of our doors use a low profile part m certified zero threshold design which means there is very little framework to step over while entering.
All of our buildings are fully insulated using the latest technologies to keep you warm in the winter and cool in the summer.
