How you procure a building matters almost as much as who builds it. In Ghana, “design and build” and “turnkey” are labels firms apply freely but rarely explain. This guide explains the two real routes — design-build under one accountable team, and traditional design-bid-build with separate designer and contractor — and lays out the trade-offs honestly so you can choose the one that fits your project. Contractors Ghana delivers both and has built since 1980. Request a consultation: +233 23 063 0030.
The Two Routes, Plainly
Traditional (Design-Bid-Build)
You appoint an architect to design the building, then separately put the completed design out to tender and appoint a contractor to build it. Design and construction are two contracts with two firms.
Design-Build
You appoint one team that takes the project from concept through design, BoQ, permits and construction to handover. The designer, engineer, quantity surveyor and builder work under a single accountable contract.
How They Compare
| Dimension | Traditional (design-bid-build) | Design-build |
|---|---|---|
| Accountability | Split — designer and contractor can blame each other | Single point — one team owns the outcome |
| Cost certainty | A full design lets you tender competitively, but variations are common | A BoQ early, with the builder costing the design as it develops |
| Speed | Sequential — design fully complete before tender and build | Overlapping — design and early works can run in parallel |
| Design control | High — you own the design before anyone prices it | Shared — the builder’s buildability input shapes the design |
| Best for | Buyers who want competitive tendering and a fixed design first | Buyers who want speed, single accountability and early cost input |
The Honest Trade-offs
Traditional gives you design control and competitive tendering. You can take a finished design to several contractors and compare priced bids. The cost is time (the design must be complete before anyone prices it) and a split of accountability — if something goes wrong on site, the designer and contractor may point at each other.
Design-build gives you single accountability and speed. One team owns the result, buildability is designed in from the start, and a quantity surveyor can produce a BoQ early so cost is shaped, not discovered. The trade-off is that you share design control with the builder, so you want a firm whose design judgement you trust.
Neither is universally “better.” A standard residential build often suits design-build (speed, single accountability); a complex or design-led commercial project where competitive tendering is required may suit the traditional route.
What Stays the Same Either Way
Whichever route you choose, the non-negotiables hold:
- A quantity-surveyor Bill of Quantities is your real budget — not a per-square-metre guess. Material unit prices are published (cement roughly GH₵85–130 a bag, rods GH₵6,300–11,000 a ton), but your total is on the BoQ.
- The build is to L.I. 1630 and the Ghana Building Code (GS 1207:2018).
- The building permit (and EPA permitting, L.I. 1652, where required) is secured before work starts.
- Registered professionals — architect (GIA), engineer (GhIE), quantity surveyor (GhIS) — on projects that require them.
How to Decide
- Choose design-build if you want one accountable team, speed, early cost certainty, and you are building a home or a straightforward commercial project.
- Choose traditional if you want to own a complete design before pricing, run a competitive tender, and the project warrants that process (often larger or institutional work).
- Either way, insist on a sectioned BoQ — it is your protection against the number that doubles mid-build, regardless of route.
How Contractors Ghana Delivers Both
- Design-build under one accountable team — design, BoQ, permits, build and handover
- Traditional delivery where you bring a completed design to tender
- Quantity-surveyor BoQ on every project, a real number not a guess
- Builds to L.I. 1630 and GS 1207:2018; permits and EPA (L.I. 1652) handled
- Established 1980 — written warranty and accountability either way

Frequently Asked Questions
What is the difference between design-build and traditional contracting? In traditional (design-bid-build) you appoint a designer, then separately tender and appoint a contractor — two contracts. In design-build, one team takes the project from concept through design, BoQ, permits and construction under a single accountable contract.
Which is lower in cost, design-build or traditional? Neither is inherently lower-priced — the route changes how cost is controlled, not a fixed price. Traditional allows competitive tendering of a finished design; design-build allows a quantity surveyor to cost the design early so it is shaped, not discovered. Your real budget is the BoQ in both cases.
Which route is faster? Design-build is usually faster because design and early works can overlap, whereas traditional is sequential — the design must be complete before tender and build.
Which should I choose for a house? A standard residential build often suits design-build for its speed and single accountability. We deliver both and will advise honestly for your project: +233 23 063 0030.
