The key to succeding with your DIY dwarf wall conservatory is the base and brickwork. If this part of the build it spot on then assembling the PVCu frames and roof will be a doddle!
If bricklaying is not your strong point, it would definately pay to get an expert to constuct the dwarf wall. For our part, we will supply comprehensive base plans including internal and external string lines to check the brickwork with.
This minimises any error and the conservatory will sit dead square and level on the dwarf wall when you get to that stage.
