Having worked with A Colour ID and Serena on three renovation projects over the past 5 years, I could not recommend her highly enough. Serena is immensely talented both from an architectural and design point of view. She has a genuine passion for each of her projects and is always looking to deliver the best possible end result for her client. She also has an amazing capacity for attention to detail… nothing is left to chance, which means there are no unpleasant surprises. My personal design aesthetic leans towards conservative and Serena (at times) has nudged me out of my comfort zone to deliver a fantastic outcome. The things I was perhaps less comfortable with at the conceptual stage, turned out to be the things I absolutely love the most about the finished projects! I very much look forward to collaborating with Serena again sometime in the future.

The renovation of my one bedroom apartment had to be managed remotely so the regular communication from Serena made the selection and decision making easier. Serena worked well with the builders and provided direction and advice on their work. The bathroom was completely remodelled meeting the scope of work to refresh the design and increase storage.

The new paint colour, blinds, lighting and kitchen splash back provided a modern and fresh look whilst complementing the existing flooring, layout and cupboards. 

I have engaged Agius Colour Interior Design Services twice since the renovation above for help with our townhouse in Lilyfield.
