Foreseeable problems and concerns during the site survey and designs consultation:

There were quite a few existing trees in the garden that could possibly cause deeper foundations due to the high water content in the ground.

How these problems were resolved:

The client employed a landscape gardener to dig up and re plant the trees.

Problems with Planning approval.

Yes. The planner had a problem with the size of the proposed side loft dormer. We agreed that we would reduce the size of the dormer but after we gained planning approval we re-submitted and put the original dormer size back in and added an additional roof dormer and then it was approved.

Sometimes during the planning process you need to negotiate with the planning officers to gain some sort of approval and once approved then they are more likely to approve another application which is bigger. It is coming up with a strategy to get the proposals that you want. Sometimes its better to get approval on something than get a refusal.
