Home Extensions: How To Decide To Build Up Or Add On

When making room and adding more space to your existing home, you have two choices – to extend out or build up.

While both forms of home extensions will increase the space in your home, they also deliver entirely different results.

For a more comfortable lifestyle, you need to decide whether adding on or introducing a second storey is the best choice for you and your family. This means there are a few factors you need to take into consideration.

Establish your end goal and what you want to achieve

The first step in determining the right home extension option is establishing the end goals of the project. You will need to determine how the space will be used and who will be using it.

If you are on a larger block and want to add a single room or extend one of your existing rooms to achieve more space. Then expanding by building out across a single level, might be the best solution.

If you want to add multiple rooms such as bedrooms, a new bathroom or a completely self-contained space. Then adding another storey might be the only option. Especially if you live on a smaller block or you want to retain your backyard area.
Transforming your home from a single storey to a double storey will allow you to introduce a whole new level of additional rooms. With more privacy and separation from the downstairs living areas.

As a bonus, extending upward may also improve your view from the second level. Depending on where you live, this could also improve the value of your home. If you choose to extend outward, you can add as much or as little space as needed. You may even wish to change the floorplan completely to adjust the flow of your layout. By extending out you also avoid stairs, which will make your house more accessible as the years go by.

Consider what you would rather lose (backyard or single storey build)

When planning to extend your home, you also need to consider what could be lost in your decision. In addition to the advantages, both forms of extensions feature their own losses. Making it essential for you to consider which of these will impact your family more.

While second storey additions unlock more potential for your home and increase your property’s overall value. You will lose the appeal of easy accessibility that a single-storey house offers. Stairs can deter some potential buyers including the elderly or those with physical limitations.

Whereas extending your home outwards will maintain the advantages of a single-storey while still creating more space. It will, however, increase the overall footprint of your home on your parcel of land. Reducing the size of your back, side or front yard. If you are on a large block of land, this reduction might not be significant. If you are on a smaller block you will need to decide if more inside space is worth the loss of your outdoor area.

4. Select Durable & Stylish Materials

Choosing the right materials ensures your kitchen looks great and lasts the distance. Focus on:

Benchtops: Engineered stone (like Talostone), granite, or high-quality laminate
Cabinetry: Polyurethane, timber veneer or melamine finishes
Splashbacks: Tiled, glass, or stone options for added impact
Flooring: Tiles or engineered timber that withstand heavy foot traffic

A cohesive palette of colours and finishes will help tie everything together. For a timeless look, opt for neutral tones with bold accents in splashbacks or lighting.

5. Add Must-Have Features

The right features bring luxury and ease to your kitchen. Here are a few essentials:

Pendant lighting over the island or dining area for style and ambience
Integrated appliances for a streamlined look
Soft-close drawers and doors for quiet convenience
Dedicated zones for cooking, prepping, and cleaning
Power outlets in the right places—including island benches and inside drawers

6. Consider Lighting & Ventilation

Natural light makes a huge difference in the kitchen. If possible, add or enlarge windows, or include a skylight. Combine this with layered lighting—ambient (general), task (for food prep), and accent (for display areas).

Don’t forget a powerful rangehood or exhaust fan to keep your space fresh and clean.
