Construction & Renovation

Carpentry / Timber Framing & Construction & Wood Interiors

We undertake all types of work, from complete renovations to new builds, including extensions and conversions of houses, chalets and apartments.


Today, ALTIOSA supports you as a genuine turnkey partner, managing every aspect of your project: planning, organisation, contractor coordination and site supervision through to final handover.


We select and manage qualified companies and subcontractors to ensure high standards of quality, on-time delivery and cost control.

Specialists in materials, particularly wood, we design and create bespoke spaces, both indoors and out: structures, joinery, terraces, cladding and finishes.


Our goal: to deliver a cohesive, lasting result, managed to the highest standards—with none of the hassle for you.
