Contentar

Coming soon

Contentar is coming to Italy

Contentar shows what a shipping container home really costs before you commit: a cost calculator with VAT, floor plans checked against the building rules, the permit process and a step-by-step guide.

It is live for Portugal and Spain. We are now preparing the version for Italy: rules, costs and suppliers.

What we already know about Italy

Building permitRequired

A fixed prefabricated home always needs a building permit (permesso di costruire). Wheels do not avoid it if the structure stays in place and connected to utilities. New homes cannot be created on agricultural land.[1][2]

Permit-free worksRemovable structures only

Only temporary, removable structures can go without a permit: no foundations or concrete slab, removable anchors and documented transportability.[2]

VAT4% or 10%

A finished modular home ready to live in, sold by a construction company, is treated as property: 4% for a first home, 10% otherwise. A self-assembly kit pays 22%.[3][4]

Building costs+21%

Rise in construction costs between 2020 and 2025, still rising in 2026.[5]

A summary of our research, October 2026. Rules change and can vary by region or municipality: check with your local authority before you buy or build.
