From initial assessment to final sign-off, Keystone provides end-to-end engineering services for every project type.
Homes · Extensions · Multi-family
Whether you're building your dream home, adding a second storey, or renovating an existing structure, Keystone provides the structural engineering expertise to make it safe, code-compliant, and built to last.
Offices · Retail · Hotels · Mixed-use
Commercial projects demand structural systems that balance performance, cost, and buildability. Keystone works closely with architects and developers to deliver engineering solutions that meet programme, budget, and safety requirements.
Roads · Bridges · Drainage · Retaining walls
St. Maarten's infrastructure must withstand tropical weather, heavy rainfall, and the demands of a busy island economy. Our civil engineering team designs and oversees infrastructure projects that are built for resilience and long-term performance.
Warehouses · Factories · Storage facilities
Industrial structures require robust engineering to handle heavy loads, large spans, and operational demands. Keystone designs industrial facilities that are structurally sound, efficient, and designed for the long term.
A clear, structured process from first contact to final handover.
