Working with professionals

Who to involve, when, and how a concept draft saves you money with them.

Bring the draft

A printed draft with specs, drawings and a budget makes the first meeting faster and cheaper.

Engineers and architects

They check structure, safety and code, and make the plans authorities accept.

Licensed trades

Electricians, plumbers and gas fitters do and sign off the work that needs a licence.

Builders and fabricators

They price and build from real plans, and know local suppliers.

Ask the right questions

What must change? What will it really cost? What permits do I need? What's the timeline?

Keep versions

Update the draft after each meeting so everyone works from the same plan.

Concept drafts are for planning, budgeting and talking to professionals. They are not engineering or build plans. Have a qualified professional check any design before you build or use it.
