Planning a High-Performing Home? 7 Questions to Answer Before You Brief Your Designer

The best time to define what you want from your home is before the plans begin to take shape.

If you’re planning to build a high-performing home, there are a few important questions to ask yourself before the design begins.

How do you want your home to feel throughout the year? How much space do you really need? How might your household change over time? And which aspects of the home’s performance are most important to you?

The earlier you consider these questions, the easier it becomes to design a home that suits your lifestyle, site, budget and long-term goals.

Green Abode has been designing and building high-performing SIP homes since 2015. One lesson we have learned is that many of the decisions with the greatest influence over comfort, energy use and construction costs are made before building begins. Once the floorplan, orientation and overall building form have been decided, changes can become more difficult—and often more expensive—to make.

Here are seven questions worth working through before you brief your designer:

1. How do you want your home to feel throughout the year?

Begin with the experience you want to have inside your home—not simply how you want it to look.

Think about a cold Wellington morning in the middle of winter. Would you like the whole house to feel comfortable when you get out of bed, rather than only the room with the heater? Would you like to avoid cold draughts and condensation on the windows?

Now think about a hot summer afternoon. Do you want the house to remain comfortable without relying heavily on cooling? Is fresh, filtered air important to you? What about quietness, consistent temperatures or reducing allergens inside the home?

These are useful outcomes to include in your design brief because they help your designer understand how you want the home to support your daily life. The technical fundamentals of a high-performing home remain the same: a well-insulated and airtight building envelope, high-performing windows, appropriate shading and controlled mechanical ventilation. Your brief helps determine how these are applied to your site, layout and lifestyle.

If you are still exploring the idea, our guide to what makes a high-performing home explains how these different elements contribute to everyday comfort.

2. How will you actually use the home?

A good design should respond to the way you live—not force you to fit your life around the floorplan.

Think through an ordinary week. Who is at home during the day? Does anyone work from home? Do you regularly host family or friends? Do you need somewhere for muddy shoes, sports gear, pets or hobbies?

Would a second living area genuinely be used, or could that space serve a more useful purpose?

It can help to consider the movement between spaces as well. Where will groceries enter the house? How close should the kitchen be to outdoor living? Does someone need a quiet room away from the main living area? Would morning routines be easier with a different bathroom or storage arrangement?

These everyday details may seem small, but they often determine whether a home feels intuitive and easy to live in.

3. How much space do you genuinely need?

It is easy for a new-home wish list to grow. An extra bedroom, second lounge, larger hallway or oversized garage can each appear reasonable on its own, but together they add substantially to the floor area.

Every additional square metre must be built, insulated, ventilated, finished, heated and maintained. A smaller, carefully planned home can therefore offer better value than a larger home containing spaces that are rarely used.

This does not mean making the home feel cramped. Thoughtful layouts, good natural light, useful storage and rooms that can serve more than one purpose can make a compact home feel generous.

If your budget is limited, reducing unnecessary floor area and keeping the overall building form simple may also allow you to protect the elements that will influence performance for decades. We discuss this further in 6 Ways to Keep Building Costs Down for Your Home.

4. How might your household change over time?

You are designing for the people who will live in the home now—but it is worth looking further ahead.

Could children arrive or eventually leave home? Might an elderly parent live with you? Could a bedroom become a home office, guest room or hobby space? Would it be helpful to have a bathroom and bedroom on the main level? Could wider doorways, easier access or a more flexible layout make the home work for longer?

You do not need to predict every future possibility. However, considering the most likely changes can help you create adaptable spaces without necessarily increasing the size of the home.

The goal is to design a home that supports your life today while remaining useful as your needs change.

5. What opportunities and constraints does your site present?

The section should help shape the home—not simply provide somewhere to place a predetermined plan.

Sunlight, prevailing winds, views, neighbouring buildings, trees, slope, access and the location of services can all influence the design. In Wellington, Kapiti and the Wairarapa, exposure and site access can be particularly important considerations.

For example, orienting living spaces and glazing thoughtfully can help the home benefit from the sun. At the same time, shading and window placement need to be considered so that the house does not become uncomfortably warm in summer. A steep or restricted site may also affect the foundations, construction access and overall budget.

Understanding the site early gives your designer a better opportunity to work with its advantages and address potential complications before the design becomes too advanced.

We have seen the effect of site constraints firsthand. On one steep Wellington section, vehicle access was so limited that the SIP panels had to be delivered by helicopter. That was an unusual project, but it illustrates why slope, access and material delivery need to be considered before the design becomes too advanced.

6. What are your performance priorities—and where should the budget be protected?

Most projects involve choices. The important thing is to decide which parts of the home should not be compromised before the budget comes under pressure.

For a high-performing home, these priorities may include:

• A well-insulated and airtight building envelope

• High-performing windows and doors

• Carefully designed mechanical ventilation

• Good moisture management

• Reducing thermal bridges

• Durable materials and construction details

• Lower ongoing energy demand

These elements work together. A high-performing home is not created by selecting one impressive product or adding isolated upgrades near the end of the design process. Our article about why high-performance homes are designed as systems explains why the connections between insulation, airtightness and construction details matter.

It is also helpful to separate your genuine priorities from the features that would simply be nice to have. If changes are required later, you will be in a better position to simplify the size, shape or finishes without losing the original performance goals.

In our experience, budget pressure is easier to manage when the performance priorities have been agreed at the beginning. This gives the homeowner, designer and builder a clear basis for deciding where the design can be simplified without undermining the qualities the home was intended to deliver.

7. How will you test the design before it is built?

A set of plans can show you the layout and appearance of a home. It cannot, on its own, tell you how comfortable or energy-efficient that home is likely to be.

Energy modelling provides a way to assess the proposed home during the design stage. Different options can be compared, such as changes to glazing, insulation, orientation or shading, while adjustments are still relatively straightforward to make.

This can help identify where additional investment is worthwhile and where a more expensive specification may provide little meaningful improvement. Most importantly, it gives the design team better information before construction begins.

Planning a High-Performing Home Starts With a Clear Brief

When planning a high-performing home, you do not need to arrive at your first design meeting with every detail resolved.

Your initial brief might include:

• Who will live in the home now and in the foreseeable future

• How you use your home from day to day

• The spaces you genuinely need

• How you want the house to feel in winter and summer

• Your indoor-air-quality and energy-use priorities

• What you already know about the site

• Your overall budget and the areas you do not want to compromise

• Any future flexibility or accessibility you would like to allow for

From there, your designer can begin translating those priorities into a home that responds to your household, your land and the way you want to live.

Green Abode provides architectural and design services for bespoke high-performing homes, from the initial conversation through to detailed design, pricing and construction.

What happens next?

Once you have defined what you want your home to achieve, you can begin working through the practical decisions involved in bringing it to life.

If you are considering building with Structural Insulated Panels, our guide Building a SIP Home: What You Need to Know Before You Start covers the next stages, including design details, quoting, product selections, construction and completion.

The best-performing homes do not happen by accident. They begin with a clear understanding of the people who will live in them and the outcomes that matter most.
