How Much Does it Cost to Build a Duplex in Melbourne?

Planning to build a duplex in Melbourne?

Many homeowners in Melbourne are opting for dual occupancy development over renovations as a strategy for adding value to their property.

Building a duplex on a vacant block is also a cost-effective approach for homeowners looking to get into their dream home without significantly adding to their mortgage. Of course, a duplex will cost more than a freestanding home, but the extra value from having two properties on one block can be significant.

Whether restructuring an existing property or building from scratch, you will want to know how much does it cost to build a duplex in Melbourne?

How long does it take to build a duplex in Melbourne?

A duplex is an attractive option for homebuyers who plan on building two properties, selling one, and then using the proceeds to reduce their mortgage significantly.

A development application will mean that a duplex will often take longer than the average freehold property and can take anywhere from 12 weeks to 16 months, depending on its size and complexity.

Duplex considerations

There are a few more considerations to keep in mind when building a duplex. Homeowners should understand that the property may require an easement.

When designing the duplex for investment, homeowners will need to ensure the design costs remain in line with the expected returns.

Duplex construction is more involved than standard homes, so it’s essential homeowners seek builders with a lot of experience in their development and construction.
