Arcvelop Investor Group

Arcvelop Investor Group (AIG) was formed in 2021 by Directors, Marc Turnier, Andrew Graham and Mike Clay. With over 25 years of combined property experience, AIG was created to develop neglected characterful properties into new commercial and residential mixed use schemes. Delivering high quality, unique design solutions is at the forefront of every development.

With existing portfolios across the UK, AIG saw the opportunity to combine the skills of the Directors and focus on three prominent UK locations where each of the Directors are based, London and Kent, Norwich and Sheffield.

AIG now has a development pipeline of 30 units and are working closely with several private investors. If you are interested in working with us please click here to discuss investment options.
