The company

A company of tradespeople, not layers of subcontracting

Founded in Lille in 2004 by Marc Delattre, a bricklayer by trade, Équerre Nord now employs 38 people and carries out most of its work itself.

Our story

It all began with masonry jobs for homeowners in Vieux-Lille. Clients then asked for a plumber, a roofer, an electrician: we chose to hire them rather than go looking for them.

Twenty years on, the company brings together six trades and a design office. It is run by Claire Delattre, an engineer, who joined her father in 2016.
