Frequently Asked Questions
Planning Reports we have taken through planning
Coastal National Park Renovation
“Building near the coast brings endless scrutiny. The site plans and visual impact statements they drafted were so thorough that the planning committee granted permission without asking for a single tweak.”
External Steel Fire Escape
“We needed a secondary escape route for our first floor office. The drawings balanced safety rules with visual appeal, passing planning on the first attempt.”
Air Source Heat Pump Housing
“Placing an external heat pump unit near our boundary needed explicit planning permission. The noise assessment and drawings provided got us approved without complaints from neighbours.”
