The Process

Want to buy a garden room? Here is our step by step guide to tell you everything you need to know and help explain our order process from start to finish.

We have created 4 standard ranges; The Finsbury, The Mayfair, The Dulwich and The Hoxton. However all of the components are interchangeable, enabling us to offer a complete bespoke service and help you buy the garden room you desire. 

The Finsbury Garden Room display building

Select your style

We have 4 different designs of garden rooms on offer; The Finsbury, The Mayfair, The Dulwich and The Hoxton. All of which bring their own unique style to your garden. At this stage, it is just about selecting the overall shape of the building as all of the windows and doors are interchangeable and the same applies with the external cladding, but more on this later. 

Decide on the size

The next stage is to agree the size of your building. Please remember all of our sizes are external and therefore the maximum size of the building. A couple of things to consider when making this decision:

Free Site Survey

We offer a free of charge, no obligation, site survey to all potential customers. We feel this is an important part of the decision making process, to ensure the designated area is suitable and assist you in designing your ideal garden room. We will discuss the construction process, measure your garden space and assess the access to your premises. Depending on your location this will be either a visit to site or via sykpe.

Planning Permission

Our garden rooms have been designed to comply with permitted development rights and therefore planning permission is not usually required. If the building is being placed within 2m of your boundary it should remain under 2.5m in height, if it is placed 2m or more away then you can increase the height up to 3m. To find out more about permitted development take a look a the planning portal by clicking here.

Choose your doors & windows

As standard all of our buildings come with the uPVC doors & windows as shown in the display image, see below to see what included for each model. However all of the doors and windows can be changed / added / removed or upgraded to aluminium if you wish. 

What's included as standard?

As standard, The Finsbury garden room prices include the following:

  • French doors 1700mm x 2000mm with fixed pane either side 500mm x 2000m in white uPVC
  • Casement window 650mm x 1120mm in white uPVC

The additional options

We offer both Aluminium and uPVC doors and windows, which option you go for comes down to your personal preferences, your budget, and the factors that are important to you. Every homeowner is different and since uPVC and aluminium tie on so many factors particularly thermal efficiency and security it’s not as simple as saying one is better than the other.

Aluminium windows have come on leaps and bounds over the past 10 years in terms of affordability, durability, and thermal efficiency, and we expect them to only continue to grow in popularity. However, there will always be a place in the market for uPVC thanks to its affordability.

All of our French & Patio doors and all windows options can be made in either uPVC or Aluminium. Bifold doors are only available in Aluminium. These can be made in a variety of sizes and colours to suit your configuration. Please speak to our sales team for prices.

Each garden room includes their standard doors in the price, however your can alter these if you prefer a different style. We offer 3 main styles, as shown below, which can be made to your exact dimensions. 

Please note BiFold doors are only available in aluminium.

All of our door and window options can be made in any RAL colour, exactly the same as when choosing your doors and windows for your house. You can change the colour of your doors and windows on any of our garden rooms, this includes external and internal. Here are some of our popular combinations:

White windows & doors


White external / white internal is our most cost effective option.

The Mayfair Garden Room shown in Cedar


Grey external / white internal is our most popular option.

The Mayfair Garden Room shown with composite cladding


Black external / white internal is becoming more and more popular.

Choose your external cladding

Standard Cladding : Larch

As standard the prices include 21mm Grade A Larch cladding. Larch is an extremely durable type of external cladding, it comes in a range of warm hues; from orange to red-brown, but over the years it weathers to a very desirable silver-grey. The colours are striking yet inoffensive and natural, creating a natural feel to the building.

Optional Upgrades:

Burnt Larch: An option whereby our Grade A Larch has been fire treated to give a blackened appearance to the timber. This creates a more rustic look and feel to the building.

Cedar cladding: Renowned for it’s ‘natural beauty’; the reddish hue, tight grain patterns and soft texture make it a popular choice.
Composite cladding: Offering an ultra-modern look. Composite cladding is available in a wide variety of coloursand grains.


All of 4 cladding options offer minimal maintenance and be fitted horizontally or vertically.

Finalise internal options

There are so many different ways you can use your garden room and these various different uses will effect how you would like it finished internally. For example, a workshop would be better suited with a ply line finish whereas an outdoor living area would benefit from a full plaster finish and internal painting.
