Choosing a builder is one of the most important decisions when building a new home. A good builder can make the process smooth and predictable, while the wrong choice can lead to delays, cost overruns, and stress.

​

Many homeowners receive one quote and assume it represents the true cost of building. In reality, quotes can vary significantly depending on what is included.

​

This guide explains how to properly compare builders so you can choose the right one for your project.

​​

​

Step 1 — Get Multiple Builder Quotes

The first rule when choosing a builder is simple:

Always compare multiple quotes.

Different builders can price the same house differently depending on:

• materials and specification

• allowances included in the quote

• project management costs

• construction methods

Getting two to three quotes allows you to see the market range and avoid overpaying.

​​

​

Step 2 — Compare What Is Actually Included

A common mistake homeowners make is comparing only the total price.

Instead, review what is included in each quote.

Items that can vary between builders include:

• foundation type

• cladding materials

• roofing materials

• kitchen appliances

• flooring

• heating systems

• landscaping

A cheaper quote may exclude important items that appear in another builder’s price.

 

​

Step 3 — Check the Price Per Square Meter

Comparing the price per square meter helps identify pricing differences between builders.

Typical New Zealand construction ranges:

​

Entry-level home

Basic design, standard materials, single level, flat site 

$2,800 – $3,500 per m²

​

Mid-range home

Quality fixtures, engineered timber, modern kitchen & bathrooms

$3,500 – $4,800 per m²

​

High-spec home

Architect-designed, premium materials, double glazing, underfloor heating

$4,800 – $6,800 per m²

​

Luxury / Architectural home

Bespoke design, high-end finishes, complex builds, steep sites

$6,800+ per m²

​

If one quote falls significantly outside these ranges, it’s worth asking further to understand if there's a valid reason why, rather than just dismissing the quote.

 

​

Step 4 — Check Builder Experience

Not all builders specialise in the same type of home.

When comparing builders, ask:

• How many homes do you build each year?

• Do you specialise in new builds?

• Have you built similar homes before?

Builders who regularly construct homes similar to yours are more likely to deliver predictable results.

 

​

Step 5 — Review Past Projects

Looking at past work helps you evaluate a builder’s quality.

Ask builders to provide:

• photos of recent projects

• completed home addresses

• examples of similar builds

If possible, visit one of their recently completed homes.

 

​

Step 6 — Speak With Previous Clients

References are one of the best ways to evaluate a builder.

Ask previous clients questions such as:

• Did the build finish on time?

• Did the price change during construction?

• Was communication good during the project?

Good builders will usually have happy clients willing to provide references.

 

​

Step 7 — Understand the Contract Type

Most builders offer one of the following contracts:

Fixed Price Contract

The construction price is agreed before building starts.

This provides greater budget certainty.

Cost Plus Contract

The homeowner pays the actual construction cost plus a builder margin.

These contracts are often used for architectural homes but carry greater financial risk.

 

​

Step 8 — Understand Allowances and Provisional Sums

Some quotes include allowances for items that haven’t been fully specified.

Common examples include:

• kitchens

• bathroom fixtures

• flooring

• lighting

If these allowances are too low, the final cost may increase during construction.

 

​

Step 9 — Compare Build Timelines

Construction timelines can vary between builders.

Ask each builder:

• how long construction will take

• when they can start

• how many homes they build at the same time

A realistic timeline is often better than an overly optimistic one.

 

​

Step 10 — Choose the Right Builder, Not Just the Cheapest

While price matters, the cheapest quote is not always the best option.

Consider:

• builder experience

• quality of previous work

• communication and project management ability

• clarity of the quote

 

The difference between builders isn’t just price — it’s what you get for it.

Choosing the right builder from the start can save significant time, cost, and stress throughout the build.
