Door and Windows

As standard all of our buildings come with the uPVC doors & windows as shown in the display image. However all of the doors and windows can be changed / added / removed or upgraded. When it comes to doors and windows there is a lot to choose from! For example; the material they are made from, the style, the price and of course the colour. Here is a little more detail on the options available:

uPVC or Aluminium?

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.

Exterior 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 colours and grains.

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

Internal Options

All internal walls are lined with foil backed plasterboards and a full plaster finish, as standard. This leaves your garden room ready for decorating.

Strematch Internal Finish

If you would prefer a different finish, you can upgrade to Strematch. Strematch cladding creates a high-quality tongue and groove paneling appearance. The additional cost for a strematch finish is detailed below.

We also offer an internal paint upgrade, this will ensure your garden room is ready to use the minute we hand over the keys. The additional cost for internal painting is detailed below.
