Handing the whole project to one contractor, or building the structure and finishing separately, changes cost, control and how long you stay involved.
Owners in Saudi Arabia routinely choose between handing over the entire house to one contractor and building the structure first, then arranging finishing separately. The decision is often framed as a cost question, but it is really a question of how much of your own time and judgement you intend to spend.
Turnkey delivery at a glance
One contractor delivers a complete, habitable house against one contract. Coordination between trades is their problem, and a single party is responsible for the result.
Structure first, finishing later at a glance
The contractor delivers the structure and envelope, and finishing is procured separately, sometimes after a pause and sometimes trade by trade.
Accountability for defects
Turnkey delivery: One party owns the result, so responsibility for a leak or a crack cannot be passed between trades.
Structure first, finishing later: Responsibility fragments at every interface. The waterproofing contractor and the tiling contractor will each point at the other.
Cost visibility
Turnkey delivery: You see one price and must trust the internal allocation, which makes the specification document your only real protection.
Structure first, finishing later: You see each trade priced separately, which is more transparent but requires you to identify what nobody has priced.
Programme
Turnkey delivery: Sequencing is planned as one programme, and the contractor bears the cost of their own delays.
Structure first, finishing later: Gaps between trades are normal, and each gap costs time that nobody is contractually responsible for.
Demand on your time
Turnkey delivery: Concentrated at the start, in specification and approvals, then reduced to supervision and decisions on variations.
Structure first, finishing later: Spread across the whole project, with procurement, coordination and dispute resolution continuing to the end.
Flexibility to change
Turnkey delivery: Changes are possible but priced as variations outside competition.
Structure first, finishing later: Changes are easier before each trade is engaged, which is the main practical advantage of the phased route.
When turnkey delivery wins
- You want one accountable party rather than a chain of overlapping responsibilities.
- Your time is limited and you cannot manage sequential procurement.
- You need a single, financeable number for the whole project.
- You value a defined completion date more than optimising each trade.
When structure first, finishing later wins
- Budget is available in phases rather than all at once.
- You want direct control over finishing materials and suppliers.
- You are willing to coordinate trades and accept the gaps between them.
- Finishing decisions are genuinely not ready when the structure must start.
How to decide
Take turnkey if a single accountable party and a fixed completion date matter more than controlling every material choice. Take the phased route only if you genuinely have the time to coordinate, or a consultant engaged to do it, and if phasing matches how your funds become available.
Before choosing, write down how many hours a week you can commit to the project for its full duration, and who decides when you are travelling or busy. The phased route fails most often not on cost but on the owner's availability.
If you are preparing to build, Domira can review your drawings, scope and contractor offers before you commit, and supervise delivery against the programme and specification you agreed.
Frequently Asked Questions
Is the phased route actually cheaper?
It can be, because you buy each trade competitively and keep the coordination margin. It can also be more expensive, because gaps between trades extend the programme, rework at interfaces is common, and small packages lack the buying power of a single large order. The saving is real only if you coordinate well.
Can I take a middle path?
Yes, and many owners do. A common arrangement is turnkey to a defined finishing standard, with named items such as kitchens, joinery or landscaping carved out and procured directly. Carve-outs must be written into the contract so the main contractor prices around them rather than discovering them later.
Who holds the warranty in a phased arrangement?
Each contractor warrants its own scope, which is precisely the weakness. Where two scopes meet, such as waterproofing under tiling, define in writing who is responsible for the interface and who must attend if a defect appears there.
