Door Options

Within our workshops, we house our own Joinery Works where we make the doors for our Garden Rooms.

Our doors are constructed from hemlock, which is a timber particularly suitable for doors, as apart from being durable, it is far less susceptible to movement and warping than other timbers traditionally used for doors.

The Garden Room doors are three quarter double-glazed using 4mm toughened safety glass, finished with polished brass or chrome furniture, a 5 lever mortise lock and fitted with draught excluders. 

You can opt for leaded, Georgian style or plain glass within your doors. 

With our Garden Rooms, you can have double doors, an extra door set, or a solid joinery door (if you have a storage partition as part of your design). You can also have an internal door to access another partition.

Window Styles

To afford a light and airy feel our Garden Rooms come with 4 sets of windows. 

The windows are all double glazed with 4mm toughened safety glass, they are all opening, and are finished with polished brass or chrome furniture and fitted with draught excluders. 

You can choose from plain, leaded or Georgian-style windows.

Roof Options

Our Garden Rooms come with your choice of roof covering: select either Cedar Shingle Tiles or Slate Effect Roofing Tiles in terracotta or grey. Both of these roof coverings add longevity to your Garden Building, they don't require much maintenance, and they are attractive and sit harmoniously in outdoor settings.

Cedar Shingle Tiles

We use only the finest quality Canadian Blue Label Cedar Shingles expertly tiled by our own skilled craftsmen to give a traditional finish which will 'silver' with age. They are expected to last 25-35 years and they complete the look of your Studio.

Grey Slate Effect Tiles

These individually laid synthetic slates finally bring nature and technology together providing the ultimate protection against UV rays, wind, hail and fire.

Terracotta Slate Effect Tiles

This roofing product carries a 50 year limited warranty. Opt for a more traditional grey or terracotta for a different look which looks great with the lighter paint shades.

Paint Options

Our Garden Rooms are available in one of two paint colour ranges: Exterior or Farrow & Ball. Both of these paint ranges offer an opaque finish with a long re-decoration cycle in a wide range of natural colours that will fit perfectly into garden environments. Please see below for information on both paint ranges.

Cladding Options

Our timber cladding is machined from very high quality Redwood grown in Northern Sweden, close to the Arctic Circle.

Due to the low temperature in this part of the world, these slowly grown trees produce a much more dense and stable timber than others. The timber mill we partner with, and have very close links to, is FSC® certified like ourselves.

We machine our cladding into particularly thick boards, and because it's a slowly grown timber with an exceptionally close grain, the additional benefits of our cladding are its strength and durability. We machine a capillary groove into our shiplap to reduce the risk of water ingress; and also give our shiplap rounded edges so that paints and stains grab and adhere with maximum effectiveness and coverage.

We clad your building in shiplap as standard, but we also offer weatherboard cladding for a more rustic finish.

Shiplap Cladding - (ex 19 x 125mm)

Weatherboard Cladding - (21>8 x 125mm)

Lining & Insulation

All our Garden Rooms are fully lined and insulated (walls, ceiling and floor) as standard. This allows you to use your new building all through the year, it also increases comfort and decreases noise levels, as well as finishes the building in a beautiful manner.


For the roof we have a 4 tier lining and insulation process; we insulate between the ply layer and the internal matchboard tongue and groove lining and finish the building with your choice of roofing material. For the walls, we insulate your building by trapping a breathable paper membrane between the studwork, which acts as a moisture trap before filling in with insulation. 

There are then 2 options for lining your Garden Room: natural matchboarding, or painted matchboarding. To have it painted, you can choose our own Ivory internal paint colour, or choose between 8 Farrow & Ball paint colours. 

Natural Matchboard Lining

We can line with our highest grade tongue and groove matchboarding (15mm) offering a natural, warm feel.

Painted Matchboard Lining

We use a channelled, secret-nailed, tongue and groove matchboarding (15mm) with 3 coats of paint in Ivory, which achieves a bright, clean and airy look.

Farrow & Ball Internal Paint

Choose between 8 neutral colours from Farrow & Ball's range to match the style and shade you're trying to achieve with your new internal space perfectly. Choose between Pointing, Shadow White, Slipper Satin, Ammonite, Elephant's Breath, Old White, Purbeck Stone and Manor House Gray.

Year-round Use

The insulation in the walls, floor and ceiling, along with the matchboard lining and double glazing will allow you to use your building in comfort all throughout the year.

Flooring Options

Our standard (ex 19mm thick) and robust floorboards are set on closely spaced tanalised floor joists, but we can also offer heavy duty (ex 38mm thick) flooring if you are planning on storing particularly heavy items or if there's going to be a lot of movement inside your new Garden Building.

As well as choosing between floorboard thickness, you can also choose to have either a lacquered finish on your floor, or you can add engineered flooring.

Lacquered Floor

Having a lacquered floor is included in the price of our Garden Rooms. The lacquer is applied to the floorboards in either Natural or Light Oak to help protect the timber, as well as giving it a nice sheen.

Engineered Flooring

This option can be chosen as an alternative to a lacquered floor. There are four different natural colours to choose from, and the engineered flooring offers a chance to further personalise your new garden building, whether you’re aiming for a traditional, rustic or contemporary style. 

Our engineered floorboards sit on top of the existing floorboards, with a layer of underlay in between the two, providing further insulating and sound absorbing benefits.

Heritage or Dark Oak Engineered Floor

Electric Pack

For lighting and using any equipment in your building, you will get an electric pack with a heater included with your Garden Room to enable you to use it all year-round.

Professionally fitted by qualified electricians who take all the wiring to a consumer unit ready for you to connect to your electricity supply. Internal wiring will be fitted behind the internal lining. 

As part of the electric pack, we provide LED spotlight sets; however, if you would prefer different lights, such as pendent or exterior lighting, that is absolutely fine. If you source the lights of your choosing, just let us know and we will fit them for you as part of the installation when we fit the electric pack.

4 double 13 amp switched sockets

A gang light switch

A waterproof double external 13 amp socket

An 8 way consumer unit: the main switch takes 2 slots - 63 amp MCB - 16 amp and 6 amp blanks

LED Spotlight sets are fixed into the ceiling of all our Garden Rooms

A Thermostatic 2kva wall heater with a digital display


To add extra versatility to your Garden Room, we also offer the option of adding partitions. You can have an external-access partition, which is generally used to add a storage or pool pump room, or you can have an internal partition or partitions, allowing you to add extra rooms, such as a toilet, or or changing room that can be accessed inside.

Finishing Touches

To finish off your Garden Room, you can also opt to have guttering to help catch excess rainfall off the roof, and choose to have Velux® windows in the roof to allow extra natural light inside.


Guttering collects the water run-off from the roof and then deposits the water away from the building: this stops the bottom boards rotting prematurely, adding an even longer life to your building. We offer the guttering in either black or white.

When installed, we fix the guttering and downpipe along the lowest side/eave of the roof, and the addition of guttering also allows you to install a water butt..

Velux® Windows

Velux® windows can be fitted in the roof of our Garden Rooms to help allow more light into your building. These are especially helpful if the building is to be installed in an enclosed area, to allow light in through the roof.

Velux® Windows


All our buildings require a level, solid concrete base of the correct size.

The single most important part of installing a garden building is the base. Bases must be:

  • Level within a 6mm tolerance to ensure the longevity of your building
  • Of the correct size (please follow the base plan we send you)
  • Square i.e. have right angled corners

A concrete base supports your building in the best possible way, adding longevity, as well as creating a substantial distance between your building and surface water.

Concrete base in a customer's gardenWe can supply a 100mm deep reinforced concrete base ready for your building, laid by our professionals, in advance of your building being installed by us. The site must be clear and level within 100mm for us to do this.

The base should always be a minimum of 50mm out of the ground to prevent surface water or puddles affecting your building i.e. rotting it.

The base you have must be made to the plans we give you when you order your building, whether we install the base, or you get a trusted builder to do it for you. 

Bases for larger buildings, and in particular garages, need to be built to exact dimensions - we create special base drawings for our garages, since they sit directly on the concrete base and must be anchored into place.

Please note: If you intend to fully or partially surround the building base with hard paving we strongly suggest the installation of a French drain between the paving and base to prevent rain bouncing off the hard surface and driving up under the building, which in turn could cause damp and rot. A French drain is a simple small trench, dug around your building and filled with aggregate that will allow surface water to drain away.

Always get your garden building base laid by a professional, whether that is us, or a local builder you trust.

We constantly strive to ensure all our materials and techniques are the best that we can source and provide. We lead the market in producing exceptional quality timber buildings. Couple this with our personal and bespoke service and you will be totally delighted with your building.

Height - 2.1m to eave height. If you need to restrict the height of your building to 2.5m, please contact us directly and we will be able to help.
