Nine Numbers To Know Before You Build Mediterranean
Every Mediterranean build starts with the same conversation, and it usually starts in the wrong place. People ask what the house will cost before they know what drives the cost. The nine figures below are the ones that decide the answer, and most of them never appear in a quote you receive.
Read them in order. Each one constrains the next.
1. $190 to $320 Per Square Foot
The national build range for this style, and the baseline every other number modifies. It sits 10% to 25% above a comparable conventional home, and the premium is not decoration. It is roofing, wall assembly, structural framing and ironwork.
If a figure you have been given falls outside this band, it is describing a different project than the one you think you are pricing.
2. $450 to $1,800 Per Square Foot, South Florida
Regional spread is wider than finish spread, and nowhere more than coastal Florida. Miami-Dade, Broward and Palm Beach run $450 to $650 on the mainland, $900 to $1,300 on the water, and $1,300 to $1,800 or more on the ocean.
The same drawings can cost three times as much one zip code closer to the water. That is site and code, not taste.
3. 18% To 25% Of The Budget Is Interior Finishes
The largest single share, larger than framing or mechanicals. It is also the share most exposed to drift, because finishes get chosen late, when the budget is already committed.
This is why finish selection belongs at drawing stage, not at the tile showroom in month eight.
4. 800 To 1,575 Pounds Per Square
What a clay tile roof weighs, against 184 to 300 for architectural shingles. Concrete tile runs 900 to 970. The framing has to be designed for that load from the start, and on a conversion, reinforcing it runs $3,000 to $8,000.
A builder who has not priced tile load has not priced your roof.
5. $11 To $25 Per Square Foot, Roof Tile
Clay installs in that range and concrete at $7 to $19, against $5 to $8 for shingles. On a 2,500 square foot roof, the gap between clay and shingles at midpoints is over $20,000.
It is also the single easiest line to substitute without the house looking cheaper from the street.
6. $8 To $14 Per Square Foot, Stucco
Three-coat cement stucco, applied over a weather barrier with a drainage plane, flashing at every opening and a weep screed at the base. The number covers that whole assembly rather than the visible coat alone.
A single acrylic coat over board quotes lower and is not the same product. It looks similar on completion and behaves differently within three years.
7. 10% To 15% Of The Total Is Site Work
Grading, drainage, retaining walls, utility trenching, driveway. Almost always excluded from a per-square-foot figure, and on a sloped or awkward parcel it runs into five figures before a foundation is poured.
A hard site can erase the entire saving on a cheaper lot. Price the site before you buy it.
8. 5% To 15% Contingency
Five to ten percent of build cost for new construction from complete drawings, ten to fifteen percent while the design is still moving. Not a mental note. A line in the budget.
It is the only line in a construction budget that can go down, and the one that decides whether month six is difficult or survivable.
9. Three To Five Quotes, Two To Four Weeks Each
From builders who have finished Mediterranean work. Fewer gives no basis for comparison. And two quotes can differ by a third while both are accurate, because they cover different scope.
Which is the real point: the number is not the deliverable. The normalization is.
Where To Take These Numbers
Square footage and the site decide everything downstream. If you only read two pages, read the cost guide for the regional bands and the builder page for the four technical questions that separate a firm that has done this from one that has not.
Both are free, both are sourced, and neither asks for your phone number.

What This Page Is Not
It is a reference page, not a quote and not a lead form. RPM Fobiz does not build, broker or refer construction work, and takes no commission from any introduction. The nine figures above are reference points for judging the numbers you are given elsewhere.
If one of them contradicts a quote you have received, the article behind it explains why.
