One of the biggest misconceptions about building a new home is that construction costs are controlled by the builder.

By the time the builder starts construction, however, many of the decisions that determine the cost of your house have already been made.

The size of the house has been decided.

The foundations have been designed.

The structural spans have been established.

The roof shape exists.

The windows have been selected and positioned.

The bathrooms and kitchen are located.

The house has been positioned on the site.

In other words, a very large proportion of your eventual building cost is determined during design—not during construction.

I sometimes describe this as the 80% Rule.

It isn't intended as a precise accounting formula. The point is that the greatest opportunity to influence the final cost of a building occurs surprisingly early in the project.

And this has an important consequence:

If you want to control your building budget, don't wait for the builder's q...

Why Two 200m² Houses Can Cost $200,000 Apart

Two houses are both 200m².

They have the same number of bedrooms, similar bathrooms, a double garage and comparable interior finishes.

Yet one costs $850,000 to build and the other costs more than $1 million.

How can that be?

When people start planning a new home in New Zealand, one of the first questions they often ask is:

“What is the building cost per square metre?”

It sounds like a sensible question. Unfortunately, it can also be very misleading.

After many years designing houses, I have found that the number of square metres is only one part of what determines the final building cost.

The geometry of the house, roof design, structural spans, foundations, glazing, site conditions and even where you position the house on the section can have an enormous effect on cost.

This is also why good architectural design can potentially save considerably more than simply choosing cheaper finishes later.

Let's look at why.

10 Features Every New Zealand Home Will Need by 2035

A house designed today could still be standing in 80 or even 100 years.

So when planning a new home, it makes little sense to design only for the way we live today.

By 2035, New Zealand homes will be dealing with higher energy demands, changing weather patterns, increasing construction costs, more electric vehicles and changing family structures. At the same time, technology will allow houses to become far more efficient in the way they use and generate energy.

The interesting thing is that the future of house design isn't necessarily about complicated technology.

Many of the most important improvements come from getting the architecture right in the first place.

Orientation, insulation, shading, ventilation, flexibility and efficient use of space can often have a greater impact than expensive technology added later.

Here are 10 features we believe will become increasingly important in New Zealand homes by 2035.

Why Rafter Roofs Make Better Use of Expensive Building Land in New Zealand. 

Are We Wasting Some of the Most Valuable Space in Our Homes?

Land in New Zealand is expensive.

In places such as Nelson, Richmond, Mapua, Motueka and the wider Tasman region, residential sections have become increasingly valuable. At the same time, construction costs mean homeowners need to think carefully about how they use every square metre of their new home.

Yet there is one surprisingly large area that is often overlooked:

The roof.

Many New Zealand houses are constructed using prefabricated timber roof trusses. They are economical, familiar to builders and structurally efficient.

But from an architectural point of view, conventional roof trusses have one significant disadvantage:

They can turn a potentially valuable part of the house into unusable space.

A carefully designed rafter roof, on the other hand, can allow the volume beneath the roof to become bedrooms, offices, storage, bathrooms or...

Why a 1.5 Storey Home Could Be the Smartest House You Build in New Zealand 

For many New Zealand homeowners, choosing between a single-storey or a two-storey home can feel like a difficult decision.

A single-level home offers convenience and accessibility, while a two-storey home can maximise views and reduce the building footprint.

Fortunately, there is another option that combines the best of both worlds—the 1.5 storey home.

At Stephan Meijer Architecture, we often recommend a 1.5 storey design because it offers outstanding value, greater flexibility and often lower construction costs while creating beautiful modern homes that respond perfectly to New Zealand sites.

What Is a 1.5 Storey Home?

A 1.5 storey home typically consists of a full ground floor with a smaller upper level.

Instead of having a complete second floor, only part of the home extends upwards.

Commonly the upper level contains:

• Master bedroom
• Children's bedrooms
• Guest bedroom
• Office
• Second living room

Why Building a New Home Can Be More Profitable When the Housing Market Is Slow

When headlines report a slowing housing market, many people postpone their dream of building a new home. They assume waiting for "better times" is the safest financial decision.

Ironically, the opposite is often true.

A slower housing market can create one of the best opportunities to build a new home. Construction costs become more competitive, trades are more readily available, and you have greater negotiating power throughout the project.

At Stephan Meijer Architecture, we've seen many homeowners achieve better outcomes by building during quieter market conditions rather than competing during a construction boom.

Here's why.

Less Competition Means Better Prices

When the property market is booming, builders are often booked months in advance.

High demand usually leads to:

• Higher labour costs

• Longer construction delays

• Increased material prices

• Limited availability of qual

Building a home is one of the largest financial investments most New Zealanders will ever make. While many people focus on the cost of construction, one of the biggest factors influencing the success of a project is often overlooked—the quality and experience of the architect designing it.

Experienced architects don't simply produce drawings for council approval. They combine years of technical knowledge, practical construction experience and creative problem-solving to design homes that are more comfortable, more cost-effective to build and more valuable over the long term.

At Stephan Meijer Architecture, we believe great architecture is about creating homes that perform exceptionally well while making every dollar of your building budget work harder.

Whether you're planning a new home, a renovation or an extension, here's how an experienced architect can add significant value to your building plans.

How to Modernise an Existing Home and Make It More Energy Efficient

Many New Zealand homes are full of character, but they often fall short when it comes to comfort and energy efficiency. Cold winters, overheating in summer, condensation on windows and high power bills are common complaints in older homes.

The good news is that you don't always need to build a new home to enjoy modern comfort. With thoughtful planning and strategic upgrades, an older house can be transformed into a warm, healthy and energy-efficient home while also increasing its value.

At Stephan Meijer Architecture, we believe that successful renovations are about much more than replacing kitchens and bathrooms. The greatest improvements come from upgrading the way the house performs while creating spaces that better suit modern living.

Start with a Master Plan

One of the biggest mistakes homeowners make is renovating room by room without considering the house as a whole.

A well-prepared renovation maste...

How to Build a Cost-Effective, High-Performance Home in New Zealand

Many people assume that building a high-performance home automatically means spending significantly more money. Images of expensive imported products, complex technologies and premium materials often come to mind.

In reality, a truly high-performance home doesn't have to cost substantially more than a standard home. The secret lies in making smart design decisions early in the project.

At Stephan Meijer Architecture, we believe that good architecture is about achieving the best possible outcome for your budget. By carefully balancing simplicity, energy efficiency and thoughtful design, it is possible to create a home that is warmer, healthier, cheaper to run and more enjoyable to live in—without unnecessary construction costs.
