I need to have built something to house a new biomass boiler and wood pellet store external to my house. I have an obvious area to build in as it’s close to the existing pipework. The area outside the house is nearly enclosed with one house wall (stone) and two stone retaining walls. The walls retain earth to a maximum height of 1 metre. Although not great to look at, the walls are in adequate condition. The floor of the area is concreted (it used to hold an old shed and an oil tank. The area measures approximately 3.4m x 2.2m.
It only needs to house boiler equipment and a pellet store and no one will live there (!) but it does need to be dry and the area can collect rain.
I’ve had two suggestions for the building. An offer to install a bespoke shed separated from the walls by a few inches and sitting on bearers on top of a concrete plinth. So there should be good air circulation. I know that the sheds the company makes are of good quality and they would also put bitumen on the sides to avoid damp and rotting. There would be a pent-style single sloping roof to the front.
Another company has offered to make a bespoke timber building, which would be strapped to the walls and tanked through plastic sheeting between inner plywood cladding and the retaining walls. They would install a ring beam and corrugated plastic sheet roof.
Although there’s a difference in cost, I primarily want to make sure that I make the right technical choice since, once built or installed, most of the building walls will be inaccessible so I need it to last 20 years at least.
Is there anything wrong with either of these approaches. Is one better than the other?
