How much does it cost to build a house in Gabon?

Ranges per m² by finish level and by city, and what they come to on a 120 m² house, from the surveys in the Gabon pack.

Updated August 25, 2026

Economy (self-build): $430 – $620 /m²
Standard: $730 – $880 /m²
Premium: $880 – $1,300 /m²

Build cost in Gabon is reasoned per square metre of finished floor, because that is the only measure that survives a change of plan. The ranges below are the ones this tool applies to Libreville, the country’s reference city, for a detached house in 2026. They cover the building itself: not the land, the taxes or the connections, which are listed further down.

Finish level	Price per m²	Basis
Economy (self-build)	258,000 FCFA – 372,000 FCFA ($430 – $620)	derived
Standard	438,000 FCFA – 528,000 FCFA ($730 – $880)	derived
Premium	528,000 FCFA – 780,000 FCFA ($880 – $1,300)	estimated
Luxury	780,000 FCFA – 1,380,000 FCFA ($1,300 – $2,300)	estimated

The town moves the number

The same drawing does not cost the same in two towns: hauling cement and steel, the price of labour and how many contractors are competing all move. Between Libreville and Port-Gentil the spread applied here is 12%. The totals below are for a 120 m² house at standard finish.

City	Price per m² (standard)	Total for 120 m²
Libreville	438,000 FCFA – 528,000 FCFA ($730 – $880)	52,560,000 FCFA – 63,360,000 FCFA ($87,500 – $106,000)
Franceville	473,000 FCFA – 570,000 FCFA ($790 – $950)	56,765,000 FCFA – 68,429,000 FCFA ($94,500 – $114,000)
Port-Gentil	491,000 FCFA – 591,000 FCFA ($820 – $990)	58,867,000 FCFA – 70,963,000 FCFA ($98,000 – $118,000)

What the number leaves out

The land, its title and the transfer fees, which in a city often outweigh the structure.
VAT, 18% in Gabon, where you build through a firm that charges it.
The building permit and design fees, which are counted separately.
Water and power connections, priced by how far the network is from the plot.
