The question we hear most from owners is: “What is the price per square metre of construction in Riyadh?” The honest answer is that there is no single number. The rate per square metre is the output of dozens of technical decisions, not a published price. This article unpacks those decisions so you understand where the number comes from — and how to read a quotation before you sign it.
Why there is no single rate per square metre
The rate is not fixed because what sits underneath it varies radically between projects. A 400 m² villa on level ground with economy finishes, and a 400 m² villa on rocky terrain with a basement, premium finishes and a lift, are both “a 400-metre villa” — yet the difference between them can exceed a factor of two.
So the first question to ask any contractor is not “what is your rate?” but “what exactly does your rate include?”
The main cost items
1. Earthworks and foundations
Excavation, backfilling, compaction, soil investigation and the foundation system. This is the most variable item because it depends entirely on soil conditions and groundwater level. Rocky ground needs breakers; weak soil may force deep foundations — either changes the budget before the first column goes up.
2. Structural frame
Concrete, reinforcement, formwork, columns, slabs and stairs. It is quantified from the structural drawings, and it is the one item that should never be negotiated down, because any reduction here is a reduction in the safety of the building.
3. Blockwork and insulation
Blockwork, plastering, waterproofing and thermal insulation. Moderate in cost, but decisive for long-term building quality.
4. MEP works
Electrical, plumbing, HVAC, security and telecom systems. These can represent a substantial share of cost in modern buildings, and rise sharply with smart-home systems and central air conditioning.
5. Finishes
By far the widest-ranging item. Tiling, marble, gypsum, paint, doors, joinery, sanitary ware and lighting — the gap between an economy and a premium finishing level can double the rate on its own.
6. External works and fees
Boundary walls, shading structures, landscaping, water tanks, plus permit fees, consultant fees and utility connections. These are the items most often forgotten in the first budget and most often appear suddenly later.
What drives the price up or down
- Soil conditions and water table: determine the foundation system and excavation cost.
- Whether there is a basement: adds deep excavation, retaining walls, double waterproofing and a drainage system — one of the most expensive single decisions in a project.
- Number of floors versus footprint: a three-storey building on a small footprint behaves very differently in cost terms from two storeys on a wide one.
- Architectural complexity: curved façades, cantilevers and large openings demand more expensive structural solutions.
- Finishing level: the single biggest driver — and the one entirely within your control.
- Site location and access: narrow streets or congested districts raise the cost of moving materials and equipment.
- Programme: pressure for an early handover means additional labour and evening shifts.

Eight questions before you sign a quotation
- Is the quote built on a detailed bill of quantities or a lump-sum rate per metre?
- What are the material specifications, named by brand and grade — not “as available”?
- Do the prices include the full MEP scope, or is that a separate package?
- Which items are explicitly excluded?
- What is the variation order mechanism and how are additions priced?
- What is the programme, and what is the delay penalty?
- What is the warranty period and what does it actually cover?
- Is compliance with the Saudi Building Code written into the contract?
The lowest quotation is not always the cheapest. More often, the cheapest is the clearest one — the quote that leaves no open item to be priced later.
Shell-only vs. turnkey
Some owners prefer to contract the structural shell only and manage the finishes themselves, assuming it will be cheaper. Sometimes it is — if you have the time and technical experience to manage several contractors and sequence the works.
But the hidden cost of that route is your time, the coordination burden, and the absence of a single accountable party when something goes wrong. Under a turnkey arrangement one party owns the whole result — which, on most residential projects, is worth the price difference. We compared both models in detail in Turnkey vs. Split Contracts.
Common budgeting mistakes
- No contingency. Always set aside a contingency for variations; projects that start with a perfectly tight budget are the ones that stall halfway.
- Forgetting post-construction items. Furniture, kitchens, landscaping and utility connections all come after “construction is finished”.
- Pricing finishes too early. Choosing a finishing level before quantities are calculated turns the number into a guess rather than an estimate.
- Ignoring the cost of time. Every month of delay has a price — alternative rent, financing, or lost opportunity.
In summary
The rate per square metre is an output, not an input. The best route to a realistic number is to start from clear shop drawings and a detailed bill of quantities, then compare quotations on specification rather than on the bottom line. At Maqayes Alola Contracting we issue a preliminary quotation after reviewing your drawings, followed by a detailed one after a site visit and quantity take-off.
