Completed Projects for Happy Customers


Mary & Derek, Albion Pk

Our clients Mary & Derek never built before and living at their current premises wanted to a cost-effective solution while staying in the area they love. In a sympathetic style to surround properties we designed a granny flat solution, Slab on ground, Vinyl Cladding, Concrete Roof Tiles and an outdoor alfresco area for entertainment and guests. Internally the property has two bedrooms each with built ins, separate laundry and open plan living/kitchen.


Robyn & Greg, Helensburgh

Robyn & Greg, approach us for a cost effective but quality Granny Flat build on what was a challenging sloping site with up to 6m falls over the build area. The site had a myriad of issues that needed to be factored in the design and approval process including a distant sewer connection and ground works in less than ideal soil conditions which only compounded the slope issues. Keeping costs down the design incorporated a raised steel structure with a large deck built in merbau timber, weatherboard cladding and Concrete roof. Internally the property has two bedrooms each with built ins and open plan living/kitchen.


Penny & Bill, Port Kembla

Penny & Bill, approach us for quality Granny Flat that was both impressive, took in the water views, didn’t blow the budget and kept their existing garagestorage structures. The site needed to take into account the existing structures for fire-rating reasons while ensuring the granny flat was still flooded with light. Keeping costs down the design incorporated a raised steel structure with impressive roof lines, blackbutt timber deckingpatio area. Internally the property has two bedrooms each with built ins, master with ensuit and additional separate bathroom and open plan living/kitchen.

A Great Investment Opportunity for Wollongong

House prices in Wollongong have risen dramatically. According to, house prices have risen $100,000 in the 2016 calendar year, a growth of 16.7 per cent. It is expected that the growth is a result of high Sydney prices, causing Sydney-based investors and homeowners to search for more affordable options.

Property investment experts now view Wollongong as a prime growth area. PropertyBuyer Managing Director Rich Harvey, points to relative affordability, market growth, and the ability to add a Sydney granny flat to obtain additional rental income as a key drawcard for investors and homeowners in Wollongong. The CEO of Raine & Horne states that properties are selling for a significant premium when they have a granny flat attached.

Granny flats can also yield a cash-positive return on investment through rental income. According to, the population of Wollongong is comprised of 66% singles, with 60% of residents renting. With a significant local university and a vibrant beachside lifestyle, Wollongong is a great option for rental investments. In Wollongong, a good granny flat can rent for $250 – $400 per week.

Match this opportunity with the ease of adding a granny flat to your home. Not only can you expect to get returns on a cash-positive investment, you can usually get a construction or equity loan quite easily. Banks and financial institutions generally love granny flats because the homeowner already has equity in the property, and the repayments should be less than the rent earned.

Whether you’re looking to add rental income, or to increase the sale value of your home, now is a great time to capitalise on market growth by adding a granny flat to your Wollongong property!

Do I need to apply through council?

No. Wollongong is covered under the State Environmental Planning Policy (Affordable Rental Housing) 2009, which means you don’t require a Development Application (DA).

Additionally, Rescon Builders have built many granny flats in the area and will ensure all aspects of your plans will meet the Complying Development Certificate (CDC) requirements, which are then approved by a private certifier before being stamped by the local council.
