Where to Start

Gemmill Projects is the unit development division of the Gemmill Homes Group. We specialise in property development and the construction of units from single house-behind-house scenarios to duplexes, triplexes and multi-unit developments.

We understand all aspects of developing your property and are here to assist you to invest in your future – every step of the way.



Our key2key service means we literally take responsibility for your development project from start to finish. You give us the keys to your old property and we will do the rest from organising demolition, water corporation fees, converting your power to underground and assisting with the titles for your home/s. We will ensure the process of developing your block is easy and stress free and, when the new property is complete, we’ll hand over the new keys.


There are 3 easy steps to understanding the potential of your block and we can take you through them at no charge.

Free feasibility and lot analysis

Discuss the best ways to unlock the potential in your block with one of our experienced Project Development Consultants.

Concept sketches and cost estimates

Our experienced design team will work alongside your Project Development Consultant to create initial designs that not only suit your block size, lot yield, R-code and local council requirements, but fit your specific requirements and most importantly your budget.
