01 — Who we are

Structure and design, from the same hands

Toni Construction brings building, architecture and interior design together — so an idea stays whole from drawing to doorway.

Led by the Sleiman family and working alongside Joseph Sleiman Architecture, we run projects with design and build closely connected. From landmark hospitality and corporate headquarters to private villas and residential towers, the same team carries a project from concept through to handover.

That is how we've delivered some of Brazzaville's most recognisable addresses — and why clients trust us with the next ones.

Three disciplines, one team

We cover the full arc of a project — the build, the architecture, and the life inside it.

Architecture & design

With Joseph Sleiman Architecture, turning a brief and a plot into buildable drawings — form, function and feasibility resolved before the ground breaks.

Interior design

The finish that makes a space yours — materials, light and detail brought together into something considered and complete.
