What height is the dwarf wall?
Dwarf wall heights are in increments of 75mm (brickwork gauge). 600mm is a common height. If you have a garden sloping downwards, consider a lower height of 450mm or 375mm. If one side of the conservatory is near to a neighbour, consider a full height wall. This could offer the opportunity for additional furnishing such as a bookcase, dresser or a beautiful painting.
