About us



Twelve Architects is an award winning international architectural practice with a main office in London. We create distinctive and memorable designs and have experience in a wide range of projects including: masterplanning, commercial, residential, transport, education, research, culture, leisure, retail and healthcare.


Twelve’s approach to all projects, regardless of scale or budget, is to gain a clear understanding of the objectives and aspirations of our clients.

Twelve designs are based on the principles of simplicity, attention to detail and intelligent use of materials.

Twelve believe that the design process should be fun and the end product is about making memorable places for people. Architecture is defined by context and culture and is styled by function. We question what is black and white to inspire the unexpected.

Our philosophy is employed at every level, to enable our employees, fellow consultants and clients to collaborate and utilise their individual expertise to enhance the full potential of a project and to deliver a shared vision.
