1. Lump Sum Fixed Price Contract
Most builders give you an estimate, start building, and then demand extra payments halfway through due to “unexpected material costs.” At Lex Duco, we invented the Design-to-Cost framework. We predict your exact cost before a single brick is laid, locking it in with a Lump Sum Fixed Price Contract.
2. Chartered Architect – Design & Lifestyle Planning
A dedicated Chartered Architect takes the time to understand your family’s dreams, lifestyle, and future needs. From space planning and architectural aesthetics to natural lighting, ventilation, and the seamless integration of indoor and outdoor spaces, every detail is thoughtfully designed to create a home that is both beautiful and functional.
3. Two Chartered Engineers – Structural Safety & Technical Excellence
Every project is supported by two dedicated engineering professionals who work together to translate the architectural vision into a safe, technically sound, and buildable reality.
The Chartered Structural Engineer develops the structural design, calculations, and specifications, ensuring strength, stability, and long-term structural integrity. The second Engineer focuses on technical coordination, construction detailing, and engineering requirements, ensuring that every aspect of the design is properly translated into the construction process.
4. Quantity Surveyor – Cost Planning & Value Engineering
Our Quantity Surveyor carefully calculates quantities, evaluates material requirements, and prepares detailed cost estimates to establish an accurate and realistic lump-sum project price.
Through careful material selection, supplier evaluation, and value engineering, the QS identifies opportunities to optimize costs without compromising quality. This ensures better budget control, minimizes unexpected expenses, and maximizes the value of your investment.
