Depending on the size of your garden room there will be 9-30 posts.
Electrical Pack
Our electrical pack comes complete with 4 double sockets, spotlights (amount depends on room size), light switch and a 50m roll of socket wire and a 50m roll of lighting wire.
Internal Panel Pack
Achieve a premium Tongue & Groove look with our primed MDF panelling. Moisture-resistant and versatile, it can be painted to match your décor.
Laminate Flooring
Bring warmth and charm to your garden room by choosing these versatile, V-groove oak floorboards. This smart oak design provides depth and character, as well as a classic look, ensuring it can blend with any décor. The wood-grain pattern and texture replicates the appearance of genuine timber without the cost of the real thing, and its manmade construction also makes it easy to clean. The V-groove edging allows for a fast and simple fit, great for those that want their garden room updated quickly. There are 3 colours to choose from which can be selected later during the ordering process - Chestnut Oak, Light Oak, Oak
