A builder's initial site assessment visit is essentially a professional fact-finding mission. The builder comes to your property, listens to what you want to achieve, inspects the site and existing structure, and gathers everything they need to put together an accurate scope of work and quote. It usually takes anywhere from 30 minutes to a couple of hours depending on the complexity of your project — and it sets the tone for the entire build relationship.
What the Builder Is Looking At
During the visit, a good builder is doing far more than just listening to your wishlist. They're mentally running through a checklist of factors that will affect cost, timeframes, and feasibility.
The existing structure and site conditions
- Foundation type — is it concrete slab, timber piles, or concrete perimeter? This matters enormously for extensions or alterations.
- Subfloor access — can services like plumbing and electrical be run without major disruption?
- Roof framing and condition — especially relevant for loft conversions or re-roofing work.
- Wall construction — timber framing, brick veneer, or concrete block each behave differently when you're cutting in doors or windows.
- Site slope and drainage — a sloping section adds complexity and cost, and the builder will be thinking about retaining, access for machinery, and compliance with the NZ Building Code.
- Orientation and sun exposure — relevant for new builds and additions, particularly with passive solar design.
Consent and compliance considerations
The builder will often have a preliminary view on whether your project will need a building consent. Under Schedule 1 of the Building Act, some minor work is exempt — but this is nuanced, and you should always confirm with your local council rather than assuming. Projects like new decks over 1.5 m high, structural alterations, or new habitable rooms almost always require consent.
If your home was built before the 1990s, the builder may flag the potential for asbestos-containing materials in areas like textured ceilings, vinyl flooring, or eaves lining. WorkSafe NZ sets out strict requirements for how asbestos must be managed on site.
Services and trade coordination
Most building projects involve other trades — electricians, plumbers, and gasfitters. The builder will be thinking about how these fit into the programme. Note that electrical and gas work is restricted work under NZ law and must be carried out by licensed professionals registered with the Electrical Workers Registration Board and the Plumbers Gasfitters & Drainlayers Board respectively. A good builder will either have trusted subcontractors or help you coordinate these trades.
What You Should Prepare Before the Visit
The more information you can share upfront, the more useful the assessment will be.
| What to Prepare | Why It Helps |
|---|---|
| Sketch or concept plans | Gives the builder a clear picture of scope |
| Any existing LIM or title documents | Reveals easements, covenants, or hazards |
| Photos of problem areas | Useful for moisture, rot, or damage issues |
| Your rough budget range | Helps the builder tailor their approach |
| List of priorities | Clarifies what's essential vs. nice-to-have |
| Timeframe expectations | Flags any scheduling constraints early |
Don't worry if you don't have formal drawings yet — many homeowners come to a first visit with nothing more than ideas and a few magazine clippings. That's completely normal.
Questions a Good Builder Will Ask You
- What's prompting this project — is it a growing family, a leaky area, or adding value before selling?
- Have you spoken to your council or a designer yet?
- Are you planning to stay in the home during construction?
- Do you have a preferred start date?
- Are there any neighbours or access issues we should know about?
These questions aren't just small talk — they help the builder identify risks and plan logistics.
What You Should Ask the Builder
This visit is also your chance to assess the builder. Consider asking:
- Are you a Licensed Building Practitioner (LBP)? (Required for restricted building work — check at lbp.govt.nz)
- How many similar projects have you completed?
- Do you carry public liability and contract works insurance?
- Will you be on site daily, or do you use a site foreman?
- How do you handle variations and unexpected costs?
- What does your quoting and contract process look like?
After the Visit — What Happens Next
Following the assessment, the builder will typically go away and prepare a scope of works and a quote or estimate. For larger projects, this may take a week or two. Some builders charge a fee for detailed quotes on complex jobs — this is reasonable practice and worth clarifying upfront.
Once you receive the quote, review it carefully. A thorough quote will itemise labour, materials, subcontractor allowances, and any provisional sums for unknowns. BRANZ has useful guidance on understanding building contracts and what to look for.
When to Call a Professional
If your project involves any structural work, new habitable spaces, alterations to weathertightness, or work on services, you need a qualified tradesperson — not a handyman. For restricted building work, only a Licensed Building Practitioner can legally carry out or supervise the work. Always verify a builder's LBP licence before signing a contract.
