Designing the perfect floorplan

Designing the ideal floor plan is one of the most important steps when building a custom home in New Zealand. It’s not just about how rooms are arranged—it’s about how your home will support your lifestyle for years to come. From the flow of everyday living to future-proofing for family changes, the right layout brings together comfort, practicality, and timeless Kiwi living.

In this guide, we’ll walk through the key considerations for choosing the perfect floorplan. Whether you’re designing your dream home on a lifestyle block near Coatesville or building in an urban suburb like Hobsonville, these tips will help you make the most of your site, budget, and lifestyle.

Start with your family's needs

Every great floor plan starts with understanding how your family lives. Ask yourself:

• Do you cook and entertain often? • Do you need quiet spaces for rest or remote work? • Are you planning to grow your family or retire here? • Think about the number and arrangement of bedrooms and bathrooms. For example:   young families often prefer all bedrooms on one level. • Multi-generational households may benefit from a separate guest wing or additional    living room. • You can never have enough storage space - design every space thoughtfully.   A well-thought-out floor plan should also evolve with your future needs.

Choose a layout that matches your lifestyle

The layout of your home shapes how it functions every day. Whether you favour open-plan living or prefer defined spaces, it’s all about getting the flow right.

Open plan vs defined spaces

Open-plan layouts are ideal for entertaining and indoor-outdoor living - great for a kitchen-lounge-dining area that opens onto a deck.

Defined spaces provide peace and privacy - perfect for media rooms, formal lounges, or work-from-home zones.

Room flow & connectivity

Is it easy to carry groceries from the garage to the kitchen? Can you keep an eye on the kids while cooking? Should the Master be positioned away from other bedrooms? Would it be useful to have a room as a multi-purpose space?

Consider practical touches like: 

Utilising the attic space above the Garage for storage A mudroom off the garage Hanging racks for drying washing in the Laundry

Prioritise privacy

Place bedrooms away from busy living areas. In two-storey homes, bedrooms are often upstairs. For single-level homes, U or L-shaped layouts create natural separation.

Control noise & maximise comfort

Position media or rumpus rooms away from bedrooms. Add insulation between internal walls. Use central hallways to buffer between noisy and quiet zones.

Sun, views and wind

Orient living areas to the north for natural light and warmth. Use large windows to frame views and walls where you want to screen a neighbour. Place garages, utilities, and bathrooms on the southern side. Account for prevailing winds when positioning decks and outdoor spaces.

Planning regulations

New Zealand’s Resource Management Act (RMA) and local council rules (like the Auckland Unitary Plan) may affect:

• Height & boundary limits • Building coverage • Site access and service connections • You’ll also need to check for subdivision covenants or architectural guidelines.

Identify your must-haves

Start with the essentials, then layer on the nice-to-haves that suit your lifestyle.

Essentials:

Bedrooms and bathrooms to suit your household Open-plan kitchen/dining/living Functional laundry Plenty of storage Garage size

Lifestyle enhancers (put these items in order of importance):

Scullery or walk-in pantry Mudroom for muddy boots and school bags Dedicated home office Second lounge or media room Covered outdoor entertaining area Wine cellar or built-in bar Guest suite Pet nook or dog wash station

Knowing what’s non-negotiable helps you design a plan that fits your budget without compromising lifestyle.

Work with local experts

Custom building in New Zealand is a collaborative process. The right team can bring your dream home to life, while staying compliant with council rules.

Partner with a builder who knows your local area and specialises in custom homes.

Designing your custom home is an exciting journey and it all starts with the right floor plan. It is much easier to move rooms around on a drawing than once the walls go up on site.
