This will be a new build bungalow. I am negotiating boundaries on my plot with the vendor. He is proposing to provide a little extra space to erect a fence beyond the outside wall of my future house (the boundary fence was missed off the plot as advertised). The construction method of my house will be timber frame, wooden I-beams (passive house) and rendered.
He has suggested 0.5m (50cm) of gap between my outside wall and the fence (a fence that will be in place throughout the build).
How much space does a contractor need to erect such a wall? Is 50 cm enough? What about scaffolding?
