Granny Flat Plans NZ: What To Look For in a Two Bedroom Layout

A two-bedroom granny flat can provide a home for parents, space for a smaller household, or somewhere to downsize while staying on a familiar property.
Choosing a layout means thinking about how that home will work every day.
When comparing granny flat plans, look closely at how the rooms fit together. Where will you eat? What needs storing? Will the second bedroom be used every night or occasionally?
At Miro Homes Wellington, our granny flat range includes the Banff and Skara, both 70m² two-bedroom homes. Here are the practical details to consider when exploring your options.
Comparing Granny Flat Plans
Start with the people who will live there. A couple downsizing from a family home may have different priorities from a parent with a child, or someone who regularly hosts overnight visitors.
Write down what each room needs to do. If the second bedroom will mainly be an office, check whether it can accommodate a useful desk and somewhere for guests to sleep. If it will be a permanent bedroom, allow for everyday clothing and belongings.
That short list will help you judge whether a plan suits your household before you get attached to its exterior.
Check the Furniture and Walking Space
Use the dimensions of furniture you own or intend to buy. A sofa symbol on a drawing may be smaller than your favourite couch, and a bedroom that fits a bed still needs room to move around it.
Look at the space available when wardrobes, drawers and doors are open. In the living area, consider whether someone can walk through while another person is seated at the dining table.
For a compact home, these checks can reveal more than the total floor area. Our guide to reading a house plan explains how to assess room sizes and everyday movement.
Look Closely at Kitchen and Laundry Space
Think through an ordinary meal, from unpacking groceries to washing up. Check where the fridge, pantry and cooking areas sit, and whether there is usable bench space for preparation.
A smaller household may still cook regularly, entertain friends or want to keep familiar appliances. Consider where the kettle, toaster and microwave will go before assuming the benches will stay clear.
Locate the laundry too. If it sits within a cupboard or another room, check appliance space, door clearance and where washing baskets and cleaning products will be kept.
Give Storage a Place on the Plan
Downsizing often involves deciding what to keep. It is easier to make those decisions when you know what storage the new home provides.
Look beyond bedroom wardrobes. Think about linen, the vacuum cleaner, coats, shoes and suitcases. If the second bedroom becomes an office or guest room, consider whether its wardrobe is already needed for those uses.
Ask what cabinetry and storage are included in the specification so you can compare the complete options.
Consider Privacy Between Rooms and Homes
Within the granny flat, look at the relationship between bedrooms, the bathroom and the living area. Will someone going to bed early be beside the television?
Can visitors reach the bathroom conveniently?
On a shared property, consider what each window will face. A living room looking directly into the main home’s bedroom can affect privacy for both households.
The position of entrances, paths and outdoor seating matters too. Consider whether each household can come and go without regularly passing through the other’s private space.
Think About Access and Future Needs
If the home is intended for older family members, discuss access early. Consider the route from the driveway, entrance steps, bathroom layout and space to move around furniture.
A single-level plan alone does not establish that a home will meet someone’s mobility needs. The section and the detailed design need to be considered together.
Tell the team about any specific requirements before choosing a plan, so they can explain whether an available design will suit.
Match the Layout to Your Wellington Section
Consider the direction of the sun, neighbouring buildings and the outdoor space alongside the floor plan. Think about where you would sit outside and how you would reach it from the living area.
The home also needs to fit the property’s access, services and applicable planning and building requirements. A listed floor area on its own does not establish whether a particular project qualifies for a consent exemption.
Our article on building a granny flat without subdividing explains the separate questions around titles, consents and site suitability.
