High-performance homes

Beautiful, comfortable, healthy homes for discerning New Zealanders

We didn’t want a cookie cutter house. We'd come from an architect designed house. We weren’t willing to compromise on something that wasn't bespoke. This is our forever home. We’re not planning to go anywhere, so we wanted to get it right.

Fed up with living in cold, uncomfortable homes?

Are you tired of your house being cold six months of the year? Perhaps damp and mould is affecting your health. Maybe you’ve lived overseas and now you can’t believe how bad New Zealand houses are. You’ve had enough, and you’re not prepared to compromise on comfort anymore.

Live your best life in a high-performance home

High-performance homes are a better way to live. And they’re the way we should build. We’re not well served by our building code here in New Zealand. It doesn't guarantee New Zealanders warm, comfortable homes. 

But I don’t believe in doing the bare minimum. When you build a house, you’re spending a lot of time, money, and energy. As your architect, I want your home to be the best it can be, not only for the joy of the architecture, but because you deserve a healthy home that’s a great space to live your life. 

“Graeme got our home exactly right. It's quiet and well-insulated. In the middle of summer on hot days, no sun came in through the windows. If we kept the doors shut, it was warm, not hot. We’re noticing now we're getting into autumn how sun's beginning to come through and warm the floor.”

My high-performance home design principles

High-performance is about more than energy efficiency. I start with passive house principles, then consider the performance of your whole building.

Highly insulated

I favour building with structural insulated panels to maximise warmth, as well as considering important elements like glazing and insulating your slab.

Airtight

An airtight home makes it easier for you to control the temperature of your home. You don’t lose hot air in winter or cool air in summer. Airtight helps exclude exterior pollution too.

Heat recovery ventilation

Ventilation helps keep the temperature of your home constant. Recover heat while filtering your air and removing dust and toxins.

Minimal thermal bridging

Thermal bridges are when the structure of your house accidentally conducts warmth outside. I work to prevent that as much as we can.

Low energy use

My building designs are at least 60% more energy efficient than a standard build. I can tell you how many kilowatts per metre2 per annum your home is likely to use.

Cladding performance

Managing external moisture is vital. In my career I’ve remediated many leaky homes, so I design the exterior of your house to withstand weather and be durable for many years.

Structural resilience

After the Canterbury earthquakes I worked assessing and repairing damaged homes. As a result, structural resilience and earthquake safety is always front of mind.

How your home fits its context

Sensitivity to your site matters. We’ll consider landform, orientation, shade, prevailing wind, neighbouring buildings, heritage, and the way you want to use your land.

“It’s lovely having a warm home. Our previous house was a beautiful old home, but it was cold. In our new home with double glazing, insulation, and underfloor heating, the warmth is one of the lovelier things about it. We moved back in the middle of winter, but we couldn't believe how pleasant it was moving around from room to room.”

High-performance homes FAQs

1

I’ve researched high-performance homes, and I’m confused. Help!

I’m not surprised. There are many options and a lot of conflicting advice out there. Sadly also, there are lots of unscrupulous people cashing in on buzz words like eco, green, and sustainable. These are terms with no clear-definition and no measurable results. I can help you understand the various home rating systems and steer clear of greenwash.

2

Do you build using passive house / Green Star / Superhome Movement principles?

My approach to high-performance homes is outlined higher up this page. I take the five passive house principles as a starting point, and build on that base, taking a more holistic approach to your home than home rating systems advocate. High-performance is about more than energy efficiency.

3

How long does it take to design and build a house?

Designing and building a new high-performance home can take between 12 months to two years. 

  • 3-6 months for design.
  • 3-6 months for documentation and consents.
  • 6-12 months for the build. 


Variables that impact on the time it takes to design and build your new home include how much design exploration you do, how long it takes to obtain consent, the accessibility of your section, whether it requires extensive work to lay foundations, and the complexity of your build.

4

How much does it cost to work with you?

Typically, architects’ fees for design, documentation and managing construction are 10% of the full cost of your project.

5

We haven’t got a big budget. Is that a problem?

Most people building a new home have a budget. Some budgets are bigger than others, but everyone makes compromises. It’s good to be upfront about your budget. I’ll be frank with you about what you can and can’t afford. Some architects ignore budgets but that is not me. I’m a pragmatist and I want you to get your home built.

High-performance homes do cost more because they require higher quality structure, insulation, and windows. However, you can get more for your budget if you go small in size but big on attention to detail. To save money, reduce the number of rooms and use spaces in multiple ways, then elevate attention to detail in the spaces you have. Also think about where you want to use your wow materials. A little bit of luxury can make a big impact. Select materials carefully and cut your cloth to your budget.

I’ll also advise you on how much contingency to allow for the unforeseen. Almost all builds go over budget, so it helps to understand that at the start.

6

How do I stop my project going over budget?

There are three ways to help your house stay on time and budget:

  1. Bring contractors into the project early. When you get your engineers and builders involved early on, they can collaborate with us to propose more cost-effective solutions. 
  2. Do all design changes in Stage 1. In Stage 2 it’s more complicated and expensive to change your design. And you really don’t want to be changing designs during construction. 
  3. Consider your fixtures and fittings during the design phase. This allows you time to find solutions you love that fit your budget. There are hundreds of choices to make building a house, and if you leave them to the last minute, you may end up making rushed, expensive decisions.

7

Can we manage the build ourselves to save money?

I oversee the build because design continues during construction, often in a trouble shooting role. The design intent for a house only comes to life at the building stage, and there are almost always challenges to resolve. 

As your architect, I visit the site regularly to check quality of workmanship, make sure materials are the ones you specified, and resolve any questions and challenges with your builders. 

I also handle contract administration, certifying monthly progress payments to your builder, reviewing any time or cost overruns and changes in scope. I make sure health and safety standards are observed on site, resource and building consent requirements are complied with, and manage council inspections. My role is also to be an impartial mediator in any dispute with your builder.

8

I know exactly what I want to build? Can you draw me up some plans?

An architect isn’t right for you. If you have a design you believe is fully resolved and simply need plans drawn up, a draftsperson will do a solid job. 

Architecture is so much more than drawing up plans – architecture is about designing beautiful, comfortable spaces where you can live your best life. A home that suits you so perfectly, that you’ll never want to move again. 

An architect is also a creative partner who can bring unexpected joy to your project. You ask for what you want, but a good architect will give you things you didn't know you wanted. That element of surprise is one of the delights of working with an architect.

9

What happens if we disagree about aspects of the design?

That will almost certainly happen. And it’s a good thing. I’m a fan of robust conversations. The thing about design discussions is they're not about winning and losing. They’re about uncovering what's important to you. 

In every build there are choices and compromises. Robust discussions help you make better choices and the right compromises. 

When we take the time to build a great relationship, those discussions become easier, because we’ve established trust. Having your expectations exceeded means being open to new ideas. That requires a partnership, and for you to be comfortable questioning your own ideas. 

Architects can have a bad reputation for designing what they want and expecting their clients to accept it. There are architects like that. But that’s not me. I will never ride roughshod over your ideas and desires, even if I challenge you to question some of them along the way.

If you’re nervous because you’ve had a bad experience with other designers or architects, I’d be happy to put you in touch with some of my clients, so you can hear from them for yourself what it’s like to work with me.

What consultants and contractors will I need to help build my home?

Building a high-performance home may need the following consultants and contractors. 

  • A geotechnical engineer to do a ground survey.
  • A land surveyor to locate the boundaries and features of your site. 
  • A structural engineer, who designs the engineering elements of your building. Not all houses require an engineer, but most do.
  • A quantity surveyor to prepare a cost estimate for your build. Getting a quantity surveyor involved at design stage can be a helpful reality check. 
  • A builder. Your architect and your builder need to have a good working relationship. It’s best if your architect, engineer, and builder have worked on projects together and have a tried and tested partnership.
  • A landscape architect to design your grounds. I include hard landscaping in your plans, but planting schemes are not my thing.


I know a range of good consultants and contractors and can organise and brief all these specialists for you.

11

Do I need a kitchen designer or an interior designer?

No. I can take care of all hard furnishings for you.

This includes:

  • Your kitchen fit out.
  • Your joinery, including kitchen, pantry, laundry, bespoke vanities, walk-in wardrobes, studies, shelves, built in storage, and entertainment units. 
  • Plumbing and plumbing fittings.
  • Door hardware.
  • Light fittings.
  • Colours and finishes for walls inside and out.
  • Floor coverings.


When it comes to choosing plumbing fittings and light fittings, I can refer you to suppliers who have a wide range and helpful, informed staff. And I can come with you to help you choose. I’ve a library of joinery samples. I can also order samples of anything you want, from carpets to paint swatches. 

The only things I don’t help you choose are appliances, furniture, and soft furnishings.

“Our new home has lived up to our expectations and the vision on Graeme’s drawing board. We can say with confidence, we don’t look at anything in our house and wish we’d done it differently. That reflects the care we took with Graeme over the whole exercise. The whole process was unhurried. It's been golden. We can’t recommend Graeme enough. As an architect and a project manager, and everything that goes with that, he's simply great.”
