1. Choose your Garden Room Size

Having selected your garden room from the range options above, it is time to plan the size.

Building sizes are based on the external wall dimensions; width x depth, excluding the 500mm overhang and decking step.

We have two height options; 2.5m (falling within permitted development) or up to 2.8m maximum.

2. Doors, Windows & Walls

All of our garden rooms can be configured to suit your needs.

We offer both Aluminium and uPVC doors and windows, in variety of sizes, styles and colours available.

You can add internal walls to any of our garden rooms to create multi-room buildings. E.g an office and storage space.

3. Pick External Cladding

As standard the prices include 21mm Grade A Larch or Thermowood cladding. There is the option to upgrade to Composite cladding or K-Render, both of which are available in a choice of colours. All cladding options offer minimal maintenance and can be fitted horizontally or vertically.

4. Finalise Internal Finish

All garden rooms include a full plaster finish to the walls and ceiling as standard. If part of your garden room is to be used as storage or a workshop, we can swap the plaster finish to 12mm ply line. We can also reinforce the wall structure with 12mm ply, allowing you to fix to the walls wherever you need to. Choose to ply as many walls as you need.

5. Select your Flooring

Laminate flooring including underlay, and skirting are included in the standard garden room price. Choose between our Grey Oak and Light Hickory.

Also includes primed MDF skirting boards, which are screwed to the walls once the flooring has been laid. This will require customer decoration including filling, sanding and undercoat.

Upgrade Your Electrical Options

External Electrical Connection

Our partnered electrician would be happy to provide you with a quote to connect the Garden Room to your mains supply, or we can leave you to arrange this independently, if preferred.

Internet & Telephone Connection

Should you wish to install a direct internet connection to your Garden Room our partnered electrician would be happy to quote for the inclusion of a data cable.

Air Conditioning Units

We work with a trusted contractor to supply and install an AC/heating unit. Alternatively, we can add an AC isolator, which is in preparation for an AC unit if you would prefer to install this at a later date.

Customise Your Decking

Standard Timber Decking

Our hard-wearing standard timber decking has been tanalised to provide durability. This process involves the wood being pressure treated, forcing the treatment deep into the timber cells. This provides long term protection from rot, fungi and insect attack. With proper maintenance you can expect many years of use out of your timber decking. Pressure treated joists are suitable for both in & out of ground contact and interior & exterior applications.

Upgrade: Timber Yellow Balau Decking

Yellow Balau is a tropical hardwood that offers a unique colour range of golden yellow browns through to pale red browns, which sit beautifully within a natural environment. It is a tight-grained strong timber with an even texture, making it very hard-wearing and durable. Balau is often used in marine construction due to its natural water resistance and anti-slip properties. It also has a natural built-in resistance to fungal decay and insect attack. By looking after your Yellow Balau timber correctly, you can expect it to gradually weather to a silver-grey colour.

Standard Composite Decking

Composite decking creates a contemporary finish to your Garden Room. It is a high-quality, UV-resistant man-made product. It is produced from a combination of recycled hardwood fibres and polymers, along with bonding agents and colour tints. The bonding agent reinforces the wooden components, and the additives improve the decking’s weather resistance. Composite decking is moisture resistant and requires minimal maintenance. It highly durable, whilst being an environmentally conscious option. We offer our composite decking in either a dark charcoal grey or lighter stone-grey colourway.

Very little. All we ask is that the area is clear (i.e. no trees, shrubs, existing sheds etc). We can build over slightly uneven ground as our base system will level off the area and we can build over multiple surfaces (i.e. a combination of paving,

No. We only ask that someone is there when the fitters first arrive so you can sign off the exact location of the building in your garden as work commences.

We will assess the access when carrying out your site survey. Generally, we do not need any more than a standard door�s width to reach the build site. Our fitters do not require access to your property, unless the garden can only be reached by going through the house.

The highest point of the building is either 2.5m, or up to 3m, as standard. These heights are chosen to comply with permitted development rights. Bespoke heights are available, if required.

All measurements listed on our website are external wall measurements. They do not include any overhang your chosen Garden Room may have.

There are no limits. We are happy to build to any size. Please bear in mind that you may have a requirement for the Garden Room to meet building regulations if it exceeds thirty square metres internally in size.

Yes. We can either work alongside your own plumber or we can do this for you. We offer the full service, if required, from drainage and sewage system installation to the fitting of white goods.

We offer acoustic insulation as an upgrade. This will reduce the transfer of sound from the building. Different acoustic treatments are available depending on the level of sound proofing required.

The Garden Rooms are fully insulated and therefore heat up quickly and retain their heat well. We, therefore, feel that underfloor heating would be unnecessary and an inefficient way to heat the building. However, although this is not a service we offer, you could have electric underfloor heating easily fitted to your garden room if it is something you particularly want to have.

No. Due to the technical construction of the Garden Rooms these must be installed by our experienced team. If you are looking for a self-build project, we would suggest looking at our Log Cabins.
