What is included in my Green Room price?

Free Site Survey

A site survey, if required, is offered free of charge. During the visit, we demonstrate the various materials and colour choices that are available. In addition, we measure, photograph and video the proposed garden room area. This is to establish access details, any obstacles and the mains electrical connection route to the consumer unit located in your home. Granny Annexe Hideaway Kitchen Installation by The Green Room

Furthermore, in the case of a kitchen or shower room we inspect your existing foul water system. We also plan the mains water route. This is to ensure the fall is correct and that the pipe gradient is enough. In some cases, we install a pump station if the pipe gradient is insufficient.

We supply and install all electrical wiring and a lighting dimmer switch. We provide double sockets as standard too. The quantity of electrical sockets supplied depend on the size of your building.

We connect to your existing house consumer unit with armoured electrical cable. The cable will be surface cleat fixed to your boundary fence or wall and connected to the Green Room. Unfortunately, in some circumstances, there may be an unavoidable extra charge. For example, if your existing consumer unit is at the front of the house. If it proves difficult to access or you need a trench to bury the cable when there is no boundary wall or fence present.
