About Quadrangle Architects

Quadrangle can be summed up in two words: inspiration realized. Their creative vision as architects is always grounded in practical realities. Since founding their firm in 1986, they've consciously built a diverse and wide-ranging portfolio.

They have never focused exclusively on a particular sector. Instead, they focus on a particular kind of client: visionary and idea-driven, yet anchored by pragmatism. Every project they undertake is guided by a set of beliefs that, appropriately, has four sides.

They believe in thoughtful design that solves complex challenges while respecting budgets and deadlines. Everyone in their firm is passionately committed to innovative thinking and advancing the evolution of design.
