Here’s Why the Home Building Advisor Process Works Best

Professional Design Review

We assess your design in the context of your existing home, reviewing structural capacity, integration challenges, and identifying risks or missing details before construction begins.

Existing Site assessment

We evaluate your current structure, access constraints, and site conditions to uncover potential cost drivers and construction challenges unique to second-storey additions.

Detailed Scope of Works
(not just Quoting from plans)

With over 25 years of experience as licensed builders, we define every element required for your second-storey addition. We independently prepare a comprehensive Scope of Works and allowances to eliminate ambiguity and ensure all critical items are captured upfront.

Apples-for-apples Builder Quotes

All builders quote from our detailed scope of works and allowances schedules so we can see who is giving you the best value. We do not accept fine print or hidden exclusions.

Builders you can Trust in Sydney that will Do a Great Job

We have worked with the Builders on our panel on previous projects under our full management. They have been assessed for financial stability and experience. We have also met with their past clients to gauge the quality of their work. To make it onto our panel, the builder needs to prove they will conduct themselves professionally and honestly during the build and will do a high quality job.
