Questions Before We Quote

Pricing, timelines, council approvals and warranty — the questions clients ask most often.

How much does a deck cost on the Northern Beaches?

A standard hardwood deck typically ranges from $8,000 to $25,000 depending on size, height off the ground, and whether stairs, balustrades or a pergola are included. Composite decking adds roughly 30–50% to material cost but lasts longer with less maintenance.

How long does a typical Bark Construction job take?

Decks usually take 1–3 weeks. Bathroom renovations run 3–5 weeks from demolition to handover. Custom builds and extensions vary with scope — we give you a written timeline with the quote.

Do you handle council approvals or DAs?

Most decks, fencing and internal renovations fall under exempt or complying development and don't need a DA. For larger structural work or extensions we'll advise whether a CDC or DA is required and coordinate with a private certifier or your designer.

Do you offer a warranty on your work?

Yes. All structural work is covered under the NSW statutory warranty (up to 6 years on major defects, 2 years on minor). On top of that we stand behind our workmanship — if something we built isn't right, we come back and fix it.

How much does a fence cost per lineal metre on the Northern Beaches?

In 2026, expect $90–$160/lm for Colorbond, $180–$280/lm for treated pine paling, $280–$450/lm for hardwood paling, and $400–$650/lm for horizontal hardwood slat fencing — supplied and installed. Read our full fencing cost guide →

Do I need council approval for a fence on the Northern Beaches?

Most boundary fences up to 1.8m and front fences up to 1.2m solid (or 1.8m with 50% transparency) are exempt development. Pool fences must comply with AS 1926.1. Heritage zones and bushfire-prone land usually need a CDC or DA.

How much does it cost to remove a load-bearing wall?

Removing a single load-bearing wall and installing a structural steel beam (with engineering certificate) typically costs $4,500–$12,000 depending on span, ceiling height, and whether services need rerouting. Read our full extension cost guide →

Do I need a DA or CDC for a home extension on the Northern Beaches?

Many compliant single-storey extensions can be approved via a Complying Development Certificate (CDC) under the NSW Codes SEPP — faster and cheaper than a DA. Heritage conservation areas, bushfire zones, and foreshore-impact properties typically need a full DA through Northern Beaches Council.
