BBL Carlton brings architects and engineers to the team to create a cost-effective solution to our client’s construction needs. Working together, BBL Carlton and our designers begin with conceptual drawings, move to construction documents, and finally construction. How is this different from traditional construction? Everyone works together from the conceptual phase through construction – no one is in an adversarial position. Everyone knows the client’s vision, budget, and schedule. Teamwork is the key to design-build construction.
