The Design Build Up Stage - How
To Plan For The Design Process Of Your Home Extension - A clients guide.

for your consideration. I often do this simply to 'stress test' your own current thinking to see any
alternatives still stand up against a clients initial set of ideas. It's good to be challenging in my

and tweaking of the suggested design before you are ready to submit for formal Planning Permission.
