After speaking with several architects about our house renovation, remodelling and extension project we decided Sean Macmillan had the best understanding of our initial ideas. Working with Sean has been a very good experience, giving us the confidence to invest in our home. Sean dealt with the inevitable challenges along the way with thoughtful solutions and have helped us realise our vision for a comfortable home, designed to meet our needs.
