A singular approach
Sq. One is an end-to-end, mixed use and residential development consultancy practice, born of 40 years’ experience and one simple belief: that by changing the way the property industry talks, thinks and operates, we add value that extends far beyond the bottom line.
Sq. One
Charlie, Guy and Jamie co-founded Sq. One in 2018. With a wealth of experience from the likes of EA Shaw, CBRE and Kier Developments in their back pocket, they decided to start with a fresh slate. The result is a consultancy with a simple mission to remain as relevant to their clients’ needs as they are to the market itself.
Together we offer a streamlined solution to mixed-use and residential property across London and beyond.
