Describe your Project

The challenges of interior renovation in Paris

Interior renovation is about more than choosing finishes. It's managing multiple trades, navigating copropriété rules, and protecting your investment. In Paris apartments, a few local factors shape what that process looks like.

Multi-trade coordination

Kitchen renovations need 5-7 trades in precise sequence. One delay cascades through all. Poor coordination means rework and thousands added to your bill.

Copropriété approval

Work affecting common elements needs copropriété approval. Non-compliance risks €9K-€45K fines, mandatory restoration, and blocked resale until resolved.

Budget control

Renovations commonly exceed quotes without oversight. Hidden issues, scope creep, and poor coordination compound costs. Clear contracts and milestone payments maintain control.

Timeline management

Poorly managed renovations take twice as long. A 3-month project becomes 6+ months. Professional coordination and clear accountability prevent delays.

Rue du Champ de Mars 22m²

Rue du Champ de Mars, Paris 7ème

Six years with the same tenant, and time had left its marks on this 7th arrondissement studio. Bathroom humidity wore the walls. Rain through the skylight stained the ceiling. The owner seized the moment between tenants to restore the studio before the next lease.

A full repaint covers every room: living room, kitchen, entrance, bathroom. Alongside, outdated radiators give way to radiant panels with digital thermostats and remote control, adjusting automatically to each room's temperature. That single upgrade lifts the DPE rating from F to E.

Two artisans, one week. The studio finds its light again.
