Transforming elegant design into beautifully built homes.

As a contemporary home builder we’re dedicated to building beautiful, architect-designed homes. In everything we do we are motivated by the following deeply-held values.


Creative design inspires us and we value architecture that enriches people’s lives. We consider it a privilege to build refined, architectural homes. 


We understand it takes a team of dedicated professionals to create something special. At every step we maintain strong, transparent relationships and communicate clearly with clients, architects, consultants, subcontractors and suppliers.


Clear communication is the foundation of an enjoyable process and a successful project. At every stage we make it clear how much has been spent and how much will need to be spent to complete the project. We also make it clear how long the project will take and revise timelines as the project advances. Our goal is to make the building process smooth, enjoyable and transparent.


Efficient systems ensure each project runs smoothly. Through extensive experience, helpful technology and dedication to detail we’ve developed a project management system to support our building of bespoke architectural homes.


JOIN is an authentic, service oriented company and we all share the same respectful attitude toward others. We love exceeding our clients expectations throughout the project right down to the final handover of their beautifully built home.


The elegant homes we’ve built proudly showcase our commitment to quality and detail. From start to finish we diligently attend to every detail in our goal to build homes that are wonderful to look at and inspiring to live in. Using quality materials and expert craftsmanship, our homes are built to minimise maintenance and last for generations to come.

What our owners say

We found Join Constructions via our architect, Sam Crawford, who, having designed an elaborate and complicated addition to a heritage listed grand federation, needed a highly skilled builder to complete his vision.

Although never having worked with Join before, Sam had seen a number of the amazing homes that Join had built for other architects and very happy home owners. Sam then convinced us to talk to Josh and Ian, the Directors of Join Constructions.

We were immediately struck by their honesty, obvious integrity and the amazing quality of the prize winning homes they’d previously built. Our favourite being the Land House in Mosman. Amazing!

We knew we’d found our builder!

During the build, Join constantly proved their skill at problem solving whilst maintaining positive relationships between all parties ie ourselves, architects, sub-contractors and neighbours.

Josh and Ian have an amazing team and we would like to particularly mention their foreman Adam Denham for his incredible patience and phenomenal eye for detail. He takes enormous pride in his work and runs a very professional work place.

Join Constructions are high end, professional builders and if you’re lucky enough for them to build your house, you will end up with an amazing, well built, bespoke home.

For a more personal reference, please ask Josh or Ian for our number and we will be happy to elaborate further.
