to see what else has been granted in the area
frankly i would not send in deatiled plans, in my experience it just gives the planners more information with which to refuse an application, go for OPP unless you are obliged to submit a full application.
if you apply, to 'build a house' and there is nothing in the local plan that precludes it there is very little for the Council to refuse your application on as you have not provided any further info. All this can be done under reserved matters later. The Council have to follow plan policies, policy H10 is a fairly vague catch all policy and reading it the Council can refuse every single applcation if it wanted to citing that policy as the reason!
also they say they wnat 350 propeties built a year and monitor that.... find out how many they have done do far this year.....
Architects... hhmmm, getb them to do the minimum,
