What we are building this month

No contractor publishes this, because it shows the jobs that slip. We publish it because you're about to hand someone a six-figure cheque and a key to your house, and you deserve to see how we behave when things go wrong.

Why Derry & Bronte is late: we opened a wall in week six and found the previous renovation had removed a bearing stud pack and never replaced it. Engineering re-work took eleven days and the homeowners paid $9,400 for a proper repair. We could have covered it and said nothing. The row stays on the board until the job closes.

Two things move these numbers more than anything else: whether your lot allows the addition without a minor variance, and what's under your existing footings. We check both at the survey, before you have spent anything with us.

Scope, in writing

What's in the number, and what isn't

Most disputes on a renovation are not about quality. They're about somebody assuming an item was included. Here is the list we hand you at quote stage.

Included, always

In every contract we write, at every price point.

  • Architectural drawings and structural engineering
  • Halton permit application, fees and all inspections
  • Site protection, dust walls and weekly clean-down
  • Disposal bins and haul-away
  • Paint, trim and finish carpentry to the new work
  • A named site lead who is on your job every day
  • Seven-year structural warranty, written

Not included, quoted separately

Named up front so it is never a surprise on an invoice.

  • Appliances, furniture and window coverings
  • Landscaping and driveway reinstatement
  • Minor variance applications if your lot needs one
  • Asbestos or knob-and-tube remediation in older homes
  • Upgrading an undersized electrical service
  • Repairs to existing work we find behind a wall
  • Your temporary accommodation, if you move out

Case study · completed

Campbellville Road

A second storey on a house that couldn't take one

62m² over garage · handed over 14 June 2026

The Ashworths wanted two bedrooms and a bathroom above their garage. Straightforward, on paper. The 1988 garage foundation turned out to be a 200mm slab with no proper footing at the north-east corner, adequate for a garage roof, nowhere near adequate for a storey of house.

We stopped at survey stage, before contract, and told them the honest version: underpin that corner and the project works, or don't and we walk away. Underpinning added $38,000 and six weeks to a job we hadn't yet been paid for. They took a fortnight to decide, got a second opinion, and came back.

The finished storey is 62m², two bedrooms, a four-piece bath, and a landing wide enough to be useful. The exterior was re-clad across the whole front so the addition doesn't announce itself, which is the part nobody notices and the part that took longest to get right.

The honest bit

We were nine days late and $6,200 over. The overage was cedar cladding that went up 14% between quote and order; we absorbed half. The nine days were ours, we under-planned the re-clad and said so at handover.
