Six stages

Discovery (week 1 to 2)

30-minute video call to confirm scope and site fit. No fee, no obligation.

02
Pre-Construction Agreement (weeks 3 to 5)

Development Application (months 2 to 6)

Council lodgement. Most Sydney councils run 12 to 16 weeks. Duration varies by LGA.

04
Fixed-Price Contract Issued

Every line item documented at the end of pre-con. No allowances, no placeholder numbers.

Demolition and Construction (months 7 to 18)

Fenced site, Buildern portal with daily updates, fortnightly site meetings.

Specialist vs volume KDR

What's different at Marvel.

Paid pre-construction, not free design

We charge for the pre-con phase so the engineering and planning work has the time it needs. "Free design" almost always means rushed drawings and cost surprises later.

Fixed-price contract after pre-con. No allowances.

Volume builders routinely use allowance line items (placeholder numbers for kitchens, bathrooms, tiling). Allowances are the single biggest source of cost blow-outs in Sydney KDR builds. Our contracts don't contain them.

Buildern portal and 6-month post-occupancy check-in
