We are more than happy to meet and discuss alternative designs and scope of works

to enable your to achieve your renovation requirements.

A cost estimate for a 1st Floor Addition for 3 Bedrooms / Bathroom / Family room - 80m2 is -$275,000-$315,000 , feel free to contact us to discuss this option.

Please read through your quotation carefully, especially noting any areas of work not included.

The next step in the process for you would be to gain financial pre-approval for the budget amount you are willing to allow for the project.

After this stage, architectural and engineering plans will need to be obtained (we can provide this service for you and have been allowed for in this quotation) and the final design completed.

Once we have these documents, we can review the quotation and make any variations or changes that may be required.

The revised quotation will then be suitable for a fixed-price contract.

At this stage, if you approve of the final quotation, a preliminary agreement will be signed, committing both parties to the project. The approval process to the council can then begin.

If you have any further queries or would like to discuss the quotation, please feel free to contact us on one of the above numbers.

You can also follow our current projects on Facebook and Instagram and view our website for further details.

Yours sincerely
