Aidan grew up in the property business, supporting his parents who ran a successful property investment and management business in the East Midlands.

Ultimately, he left a postgraduate position to set up and grow a boutique housebuilding business with an experienced partner, then drove the business to expand in two separate regions and developed a pipeline of 112 units. It was through this venture he got the bug for construction, even going on to manage a small project and gain his SMSTS qualifications. Now he is actively using that history to support Argyll in its ambitious growth plans.
