Start with scope, site and professional design
A successful house project begins before excavation. Confirm land boundaries, access, utilities, planning constraints, family requirements, future expansion and a realistic budget. Use qualified professionals for architectural, structural and building-services design.
Drawings and specifications should be coordinated before contractor pricing. Changes made after construction starts typically cost more and can delay procurement.
- Define rooms, floors and quality level
- Complete architectural and structural design
- Prepare approval documents and BOQ
- Set budget, contingency and decision responsibilities
Compare contractors on the same information
Issue the same drawings, BOQ, specifications and commercial conditions to shortlisted contractors. Compare exclusions, material assumptions, staffing, programme, payment terms, warranty and experience—not only the total price.
Use a written contract with scope, milestones, change procedure, quality checks, payment certification, retention and defect correction. Record site instructions and approvals.
Control materials, quality and cash flow
Plan long-lead materials early and match purchases to the construction programme. Approve samples and technical submittals before ordering. Inspect reinforcement, formwork, concrete, masonry, waterproofing and concealed services before they are covered.
Track budget, commitments, paid amounts and forecast final cost. Keep a contingency for design development, ground conditions and approved changes rather than spending the full budget at contract award.
