Insiders reveal the spotlight on triplex developments

Posted 9 April 2019

You’ve no doubt noticed that Perth neighbours seem to be living in closer quarters these days.

As demand for inner city dwellings continues to soar in line with evolving retail, dining and entertainment drawcards, councils are looking for ways to increase urban infill – one of which is changing zoning for land closer to the city.

That’s great news if you own a large block and are looking to unlock its true value. Zoning changes have opened the door for greater density, allowing many homeowners wishing to subdivide to fit more, on less, making triplex designs a popular development choice.

What is triplex development?

Triplex homes are built on a single lot, and comprise three residences that share a roof or a wall.

They allow unit builders to deliver more affordable options for renters and homebuyers looking to live in a better area, with investors looking at either long-term strategies focused on rental yields or short-term gains by on selling the properties once completed.

Why choose
 triplex floor plans?

Triplex building plans can be surprisingly affordable. Perth developers are attracted to the versatility of this investment option - you may live in one dwelling, while renting out the other, rent out all the units, or build and sell the lot. This versatility, allows for  

And by focusing on triplex developments as a long-term wealth generating strategy, you stand to make a sound investment.

What block sizes are recommended by triplex builders (WA)?

Level blocks with the right zoning are highly sought after for triplex developments. As a guide blocks sized 700sqm to 1000sqm, zoned at or above R30 are preferable.

A corner site usually makes development easier, while close proximity to amenities and a train station is always a must.

For example, Summit was recently called on to build a triplex development on a tight 728sqm block in Innaloo.

As experienced triplex builders, our unit development expertise led to the successful completion of two single storey unit development plans, with a double storey unit at the rear - all featuring three bedrooms, two bathrooms and a large living-dining space and an outdoor courtyard.

The single storey units received a single lockup garage and a car space, while the double storey was served by a twin lockup garage.

Another triplex development delivered by our unit builders was a corner site unit development in Wilson.

Once completed, the investor was left with three beautifully finished street frontage units, all of which were rented out immediately.

Highlights include three well-sized bedrooms, master with a walk-in robe, double garage with internal access, two bathrooms and spacious kitchens.
