Who We Are

Keystone provides over 35 years of combined experience in architecture, construction management and real estate finance; a unique combination of finance and technical capabilities

By embracing a humanitarian and business approach that considers not only the needs of the client and site conditions, but also the social and economic environment, solutions are realized that are contextual, yet relevant, profitable and visionary in their intent, function, and charm.

Our projects focus on bankable solutions that leave the ecosystem enhanced, socially sound and aesthetically pleasing.

What We Value

A significant part of our work requires physical interventions of spaces. As with any form of design, fashion, colour choices and the use of latest consumer trends are relevant, however at Keystone we ensure that the solutions are inspired by values which find physical expression in ways directly related to the particular need, location, constraints, problems and the client’s goals. We ensure that these values remain the compass to inspire our solutions.


Our lifecycle approach allows us to deliver an integrated service to clients from feasibility to completion to ensure an efficient and profitable solution


The romance of real estate is in its creative potential—a marriage of art and practicality. Our ability to think in intuitive, non- verbal, and visual terms enhances our creativity in executing our projects.

Working Contextuality

By listening and dancing to the song the site sings, we are inspired to produce solutions that are contextually harmonious


We value our integrity to the clients, to the elements of design and to the authenticity of the materials we use. What we do lives beyond us.


We are committed to creating regenerative projects which heal their environments and enhance the quality of life by thinking globally and acting locally.
