Being a truly bespoke company, we have a wide range of internal finishes too

Plater Pack

Plasterboards are fixed to the walls and ceilings and skimmed to give a luxury and homely feel. Recessed electrical sockets are fitted as standard.

Skirting boards are provided in either oak or white finish. Due to the nature of plastering, the completion of your garden room with this option will be several weeks longer to allow for drying time.

Clickwall by Unilin

You can choose from a large number of finishes and colours. Recessed electrical sockets are fitted as standard.

Skirting, edging and pelmets are usually colour matched.

For economy we offer melamine or OSB for a rustic finish. Electrical sockets are then surface mounted this is popular for workshops or art studios.

Acoustic Treatment

We discuss what the room is going to be used for and the level required before we recommend the right solution.

Typically, we would use the following treatment for the walls and ceiling
Aluminium furring mounted on genie clips
Acoustic Rockwool
2 layers of acoustic plasterboard separated by acoustic matting or ‘Green glue’
Surface mounted electrical fittings

Acoustic honeycombed door frame with acoustic glass.

For the floor we use a rubber sound matt with acoustic underlay before fitting the floor of your choice.


As standard we offer a wide range of Unilins’s QuickStep and Pergo laminate flooring.

If you are looking for something different, please specify as we work with a number of suppliers giving you the ultimate choice.


4” wide guttering is provided as standard on all garden room buildings, helping to manage the flow of water from the roof and away from your garden room.

We fit a gutter brush as standard to stop any debris forming withing the gutter.


We an ‘Firestone’ EDPM rubber roof as standard for our mono pitch and ‘Britmet’ lightweight roofing for our dual pitch roofs.

We are customer and design lead and constantly looking at other roof systems that offer longevity and add to our stunning designs.

Window & Doors

All doors and windows are fitted as standard with hard coated, low-e Pilkington K Optiwhite ‘extra clear’ double-glazing, which is argon filled and fitted with a Planitherm layer and Swisspacer providing superior insulation and energy efficiency.

We use reinforce steel uPVC or as an option,  aluminium windows and doors.


We have developed our own unique, tried and tested, concrete pile foundation system to ensure your garden room is perfectly level. What’s more, the price of our foundation system is included in the standard price of your garden room. Our concrete mini pile system is significantly more environmentally friendly than a solid concrete base, but remains just as effective. We can use our concrete mini pile system on sites with a surface undulation of up to 200mm, which means less prior groundworks and upheaval for most customers.

Depending on use and soil we also use galvanised ground screws or an insulated concrete raft.
