How Derome Erects Six-Storey Apartment Blocks in Three Days

Why It Matters

The breakthrough slashes construction time and labor costs, making high‑rise mass timber more competitive with concrete and steel. It also demonstrates a scalable, low‑carbon building model that could accelerate timber adoption globally.

Key Takeaways

• Six-storey timber block built in three days, two floors per day.
• 15 years of incremental improvements across engineers, factories, site crews.
• Full value‑chain control enables rapid product‑process integration.
• Delivery fleet switched to bio‑based diesel; bio‑insulation under development.
• 2026 Wood Central tour will showcase Derome’s system to Australian delegates.

Pulse Analysis

Mass timber is gaining traction as a sustainable alternative to concrete and steel, but speed of construction has remained a barrier. Derome’s latest achievement—raising a six‑storey apartment in three days—redefines what timber can deliver, compressing a timeline that once took weeks into a matter of days. This leap is not the result of a single invention but a disciplined, 15‑year program of incremental upgrades that align product engineering, factory automation, and on‑site assembly into a seamless workflow.

The company’s advantage lies in its end‑to‑end value‑chain ownership, from forest harvesting to finished panels. By controlling every step, Derome can instantly translate factory refinements to the construction site, eliminating bottlenecks that typically slow modular projects. Complementing the speed gains, Derome has greened its logistics with a fleet running on bio‑based diesel and is piloting bio‑insulation made from sawmill residue, a material that can lock biogenic carbon in walls for up to two centuries. These moves reinforce the firm’s sustainability narrative while reducing reliance on mineral wool and fossil‑based fuels.

For the broader industry, Derome’s model offers a proof point that high‑rise timber can be both fast and low‑carbon, potentially reshaping urban building codes and financing criteria. The upcoming 2026 Wood Central UK‑Sweden study tour will let Australian delegates witness the system in action, fostering cross‑market knowledge transfer. As developers seek quicker, greener construction solutions, Derome’s incremental, value‑chain‑centric approach could become a template for scaling mass timber worldwide.
