Services
Whole Home Renovations
We manage full renovations that reimagine your home from the inside out. From layout changes to complete structural overhauls, we help modernise, personalise and improve the way your home flows and feels while respecting what makes it yours.
​
Architectural Extensions
We deliver tailored extensions that add space, value and liveability. Whether it is a second storey or a seamless ground floor addition, we collaborate with trusted designers and architects to ensure the new build feels like it has always been part of the home.​
Start with a vision or bring your plans
We are flexible in our approach. Whether you come to us with plans in hand or need guidance from the start, we will meet you where you are. We often work alongside our trusted drafts people and architects or we can collaborate with your chosen designer.
Throughout the design process, we provide clear cost comparisons and practical guidance to help align your vision with your budget without compromising the result.

Our Process
Every project is handled by the same people who quote, plan and build your home. Our process is structured to make things smooth and stress free from the start.
STEP 1 - Initial
Initial enquiry received and we touch base to arrange a time that suits you best for an on-site consultation. We work around you.
STEP 2 - Design
If needed we’ll introduce you to a trusted draftsperson, architect or interior designer who aligns with your project goals and style.
​
STEP 3 - Planning
Once plans are ready, we provide a detailed quote that reflects your vision and budget.
​
STEP 4 - Approvals
We can connect you with a building surveyor to help manage permits and approvals as needed.
​
STEP 5 - Agreement
We finalise and sign contracts, so you have full clarity before construction begins. No surprises.
​
STEP 6 - Build
Your project comes to life. We manage the site, the schedule and the trades with consistent communication and precision.
STEP 7 - Handover
Once complete, we walk through the finished build with you to ensure everything meets our shared expectations.
STEP 8 - Support
We return for a follow-up visit post-settlement to check in and resolve any outstanding details.

We are fully licensed and insured builders, with every project covered under DBI for your protection. As Registered Building Practitioners with the VBA, we follow clear, fixed-price contracts and only work with trusted trades who share our standards. Our work is backed by structural and non-structural warranties, and we check in after handover to ensure everything continues to meet your expectations.
