duplex townhouse

Have you wondered about how to pick the right suburb for a duplex townhouse?

It’s a great question, as picking the wrong suburb can be disastrous. Some suburbs will grow in value at different rates. Some will stay stagnant. And some will absolutely boom.

And the value of property is often contingent upon the suburb.

For instance, a rapidly gentrifying suburb will see property values skyrocket. This is because it becomes desirable to live there. Young families, professionals and established people will flock to a suburb like this.

That means if you develop in a growing suburb, you will likely see a solid profit.

But if you pick a dud, you might see a loss or a break-even.

And the reason people develop real estate is to see a profit.

So, in this helpful article, we’ll share how to find the right suburb for a duplex townhouse.

To start with, we’ll explain what a duplex townhouse is. Then, we’ll explain why you might want to undertake one.

And then, we’ll get into the meat of the article and share how to pick the right suburb,

What is a Duplex Townhouse?

duplex townhouse development

A duplex townhouse is when two conjoined dwellings are constructed where there was previously one house, similar to a dual occupancy build.

These days, most duplex developments are townhouses. It’s rarer to see new single-storey units.

Why Undertake a Duplex Townhouse?

You’d want to do a duplex development for a few reasons.

The first is to maximise the value of a piece of land.

By building two where there was previously one, you can then sell each property for market value.

This is a fast-tracked way to profit.

Another reason to do a duplex townhouse might be to downsize. Some people want to live in one property, and then they will sell or lease the other home.

In days gone by, investing in existing real estate was the way to get ahead in Australia.

But more and more people are turning to townhouse development to grow their wealth.

Now, let’s dive into the rest of the article.

How to Pick the Best Area to Develop In

There are a few things to consider when picking a suburb to do a duplex townhouse development in.

We’ll drill down into them, one by one.

Block Dimensions

While there is no hard and fast rule about the type of block ripe for development, there are some hints here.

Some suburbs or areas within suburbs have lots that are roughly the exact dimensions.

You want to pick suburbs with lots that are the right size for development.

For instance, for a side-by-side duplex, an ideal amount of street frontage is approximately 15 meters.

This is wide enough to allow the two homes to sit side by side. If the frontage is bigger, that’s great.

This is not hard and fast; smaller frontages are possible, depending on the local council.

Look for Desirable Features

You want to look for desirable features and amenities in the suburb.

Those are things that homeowners, families and other people will enjoy.

For instance, this is a plus if the area has schools, daycares and kindergartens.

Ditto for golf courses, gyms, swimming pools and other leisure centres.

Furthermore, having many parks, walking trails, or other desirable features might mean it’s a good suburb to develop in.

In addition, if there are shopping strips or centres or bars, restaurants and cafes, it’s another plus.

You’ll also want to look for proximity to the CBD; the closer, the better, as people like shorter commutes and can head to town for fun and leisure.

Another consideration is the public transport options. Does the suburb have a train station or tram stops? Are buses the only PT available? People consider all these factors when buying a townhouse or looking to rent.

If there is a shortage of amenities and features, it’s not entirely ruled out, but you might want to consider if there are enough nearby that people could drive to.

Know the Area

If you consider a suburb to develop a duplex in, it pays to know the area.

Go for a drive around the suburb and take a look at the properties.

See the types of dual occupancy or duplex townhouse developments occurring.

Look for what is getting approved, which should give you an idea of what you can develop.

You can also get a feel for the neighbourhood, by looking for the abovementioned features.

Research Previous Sales Figures

When you are looking at a suburb, you need to consider the previous sale metrics.

This means searching online for sold real estate results for townhouses in the area.

This will give you an idea of the approximate sales price for your duplex homes.

If the sales prices don’t match your expectations, you might want to expand your search to other suburbs.

The raw building and labour costs will be similar, regardless of the suburb.

So, it makes sense to undertake development in an area where properties are selling for a desirable amount.

Let’s share an example.

If you are considering a suburb with an average purchase price of a million or so, you build a duplex that costs around 750-850k.

Look at the profit margin if the properties sell for around a million each.

But if the sales prices don’t match up to your intended profit, avoid the area.

You can see how it makes sense to research sales prices and compare this to your budget and plans.

And this is a reminder to know your figures, inside and out.

Consider Supply and Demand

Our last tip is about supply and demand.

You need to factor this into your decision-making about picking a suburb for a duplex townhouse.

As a rule of thumb, the further out you get from a CBD location, the more supply you’ll see on the market.

With an oversupply, the more you’ll struggle to sell the townhouse. You might even have to drop your asking price to net sales, which means less profit.

Ideally, you’ll choose a suburb with higher demand. To learn this, use the tip above about researching a suburb’s amenities and features.
