At Hive Homes we only offer fixed-price contracts because they give you total cost certainty and zero surprises. In 2026, with material prices still fluctuating (especially timber, cladding, and concrete), a fixed-price build protects your budget far better than cost-plus. Here’s the simple comparison.

A fixed-price contract (also called a lump-sum contract) locks in the total cost of your home build right at the start. Once you sign, you know exactly what you’ll pay — provided you stick to the agreed plans and specifications. The builder carries the risk of cost increases within the agreed scope.

This approach gives you peace of mind, makes bank finance easier, and lets you focus on enjoying the process instead of worrying about the budget.

A cost-plus contract (sometimes called charge-up) means you pay for the actual cost of labour and materials plus an agreed builder’s margin or fee. It can seem flexible at first, but the final price is only known once the build is complete. You carry most of the financial risk if prices rise or delays occur.

In early 2026, the Smith family in **Patumahoe** (south Auckland) came to us wanting a spacious 4-bedroom family home on their newly subdivided section. They had a clear budget and zero desire for financial stress.

We locked in a **fixed-price contract** at $788,000 (including GST) for a 219m² home — similar to our popular Hazel design. This price covered the full architecturally-inspired home with open-plan living, high-quality finishes, and everything in our standard inclusions list.

From the moment they signed, they knew exactly what they would pay — no surprises. Construction stayed on track, and we handed over the keys right on schedule. The family moved in without any extra invoices or budget blowouts.

The fixed-price gave us total peace of mind. We could focus on choosing our finishes instead of worrying about costs going up. It was genuinely stress-free from start to finish."*

This is just one of many recent fixed-price deliveries we’ve completed across **Karaka, Clarks Beach, Glenbrook, Patumahoe, and Waiuku.

While cost-plus contracts can seem appealing because you only pay for actual costs plus the builder’s margin, they come with serious downsides — especially in today’s market.

Price Spikes & Material Volatility — Timber, steel, concrete, cladding, and labour costs can still jump unexpectedly. In a cost-plus build, you carry 100% of that risk. A small delay or supplier increase goes straight onto your bill.

Project Delays — Rising costs often lead to delayed decisions while you approve extras. This can stretch the timeline by months, adding holding costs like interest, rent, and rates — plus more stress.

Endless Decisions & Admin — You end up micro-managing every variation, quote, and invoice. Many clients feel exhausted by constant choices and paperwork instead of enjoying the build.

Budget Uncertainty — What starts as a “rough estimate” can easily blow out by 15–30%. Banks also prefer fixed-price contracts because they can approve lending more confidently.

Relationship Strain — When costs overrun, tension can build between you and the builder.

In short: cost-plus shifts all the risk onto you — the homeowner. In 2026’s environment of fluctuating material costs and skilled labour pressures, that’s a gamble most families don’t want to take.

Not all fixed-price contracts are created equal. At Hive Homes, we’ve designed ours to give you genuine certainty and peace of mind.

You see exactly what you’re getting — no vague “allowances” that later turn into extras.

No Hidden Fees — We don’t surprise you with extra charges for standard items. The price you see on day one is the price you pay (except for genuine client-requested variations, which we document clearly in writing).
