Preparing building design plans for your renovations, additions or alterations to your home is our specialty. Whether it is a house raising and build under, a knock down rebuild or a small extension, McKDD can help.

We have extensive background in both architectural design and structural engineering with the relevant on site construction experience so we can pass on our design philosophy that considers input from all parties involved. We take the time to work through building details at design stage to ensure a trouble free building experience.

This allows our valued clients the peace of mind that their project has been co-ordinated and thoroughly checked to be the most affordable and cost effective it can be. You and your builder will appreciate our efforts because it will ensure your renovation building project will run smoothly and on budget.


We will personalise a design to suit your budget, timeframe and building style.


An initial consultation, FREE for a limited time, at your home or site will allow us to discuss your plans and ideas and determine the possibilities for your proposed building design, extension or renovation. We will also advise of council regulations relating to your site and any other identifiable issues.

We will then provide a fixed price written estimate of fees to continue with the project. Once a design brief and proposal are accepted, work is begun on the preliminary plans and elevations to give you an understanding of what the finished product will be. After the preliminary plans are finalised, the drawings are then progressed to Working Drawings. These are used for submission to Council and Tender and Construction purposes.
