For Ultimate Peace of Mind During Your Build​

Constant Communication

We believe that keeping you informed throughout every stage of your journey with us is crucial for you to have a positive experience. If for some reason one of our team is not able to answer a call straight away. we guarantee to return your call within 2 hours.

Financial Planning

Our Action Plan provides a fixed price that will not change unless you change your mind. If changes arise due to unforeseen circumstances, we will provide you with a written variation of the costs. This will allow you to remain in total control of your project costs ensuring your plans will stay within budget.


We pride ourselves on our personal approach with all of our clients. Gaining and keeping trust is our number one priority. This is one of the key reasons why 93% of our work comes from referrals from previous clients.


Whether you are in the design or construction stage, you will always be one of our team’s top priority. We have strong relationships with our designers and we can ensure that you will receive your completed plans within reasonable time frames. We will communicate daily with the council to help you obtain your billing consent within 20 days from submission. Every project is unique. We will create a customised Project Schedule Timeline based solely on your project to help us better organise our subcontractors and speed up your project. You will have access to the copy so you know exactly when the different construction stages will take place.

Quality Control

After construction, we will walk through your home using our 267-Point Quality Checklist. Developed over 13 years, our checklist ensures that your home is completed to the highest possible standards before handing over the keys.

Barefoot Walking Guarantee

Sites so safe, you can admire progress in bare feet!

Many of our clients choose to remain in their homes throughout the course of construction, so we place a huge emphasis on keeping a tidy, safe site. This ensures that the building experience is both as enjoyable and as easy as possible for your family, and there are minimal disruptions and as little inconvenience as possible.

The construction stage of your project is the most exciting and we understand that you are going to want to come & admire progress. 

We want to ensure you are safe when we take you through a tour of the construction at your home.
