Building feasibility and costing on the Central Coast
A realistic cost range and an honest look at your site, before you lock in plans, quotes or contracts.
Know what's realistic before you commit
Too many people spend months and thousands on designs, then find they can't afford to build them. A feasibility report or early estimate stops that from happening.
Dylan reviews your concept plans or sketches, or visits the site, and sets out the likely cost range, the pressure points and what to look into next. Every report is personally reviewed by him and is usually ready in 3 to 5 business days.
When the design is further along, a full trade-by-trade quote gives you the real number, with the deposit credited if you go ahead.

Feasibility and costing questions
Got a different question? Give Dylan a call.
Is a feasibility report a fixed-price quote?
No. It's an indicative cost range to help you decide, not a fixed price. A full quote comes once the design and selections are settled.
Do I need engineering drawings first?
No. Concept plans or sketches with enough detail are enough for a feasibility report.
