“Engineering, medicine, business, architecture and painting are concerned not with the necessary but with the contingent – not with how things are but with how they might be – in short, with design.”

Herbert Simon,
The Sciences of the Artificial, 1969


Our continuous efforts in conservation for design services are paired up with LEED (Leadership in Energy and Environmental Design), which guides the planning and implementation of our buildings through their design and construction phases within the set standards of sustainability. This in return constitutes to cost-efficiency and the development of conservational habits in our projects.

Energy efficiency is usually looked at as a high cost determinant when constructing a building, even through the initial design stages. This result is people paying less attention to conservation and energy-efficient technologies that in practicality, is both cost-efficient and resilient in the long run and is also beneficial for the environment that we live in. The solution here is the importance of balance.

To achieve the green awareness that the environment deserves comes from balancing the economics of social well being with considerations for the environment. Our team of professionals sets turnkey standards in achieving just that. Connecting architecture with construction solutions, SDC systematically synergies conceptual designs with environmental sustainability. We at SDC believe that sustainability in design/build is achieved through the communication of core project objectives and valuable benefits economically, socially, and environmentally.
