Im a draftsman, 8 years experience, most in Victoria
The rules and regs change from state to state, but also willing to help out if I can too! (I do 3d representations, detail plans, footings, drainiage and elec, timber frame stress analysis, shadow projections, submission to council plans, the works)
Drainiage and roofing is the biggest concern as the council all wonder about the extra water catchment area the roof provides, thus feeding it back into the stormwater system... they dont want to have to upgrade pipes in the area (can design that for ya to)
I specialised in WSUD (Water Sensitive Urban Design) in a major Land Development Consultancy in Melbourne
I also have a few contacts here in ACT with residential expertise so maybe I can get them in contact with you.
The initial plans can be done by anyone ,but usually require someone registered to sign off on them (approvals etc)
Theres a guy about 600m from my house here in Deakin, Rod Sheather Architects & Builders (he is a car luver too)
Will also come by one evening after work and have a geezer if you like?
Might chat about car electronics again!
