Instead of concrete or metal, this striking eco-friendly office building in Romania features a sturdy timber skeleton – making it the first large-scale CLT structure in southeast Europe. Romanian firm Tecto Arhitectura designed the building as the new office for HSR factory in Reci, Covasna. Designed for long-term sustainability, the office building draws on geothermal energy, uses energy-efficient technologies, and is topped by an extensive green roof.

Shaped like a cross in aerial view, the HSR timber office stretches horizontally from northeast to southwest and is intersected by a two-story volume with a northwest-southeast orientation. A stairway and a double-height atrium are located at the heart of the office that accommodates around 60 people. Built to minimize thermal loss, the office is built mainly of industrially prefabricated cross-laminated timber panels and gluelam elements. Given Romania’s freezing winters, the architects inserted passive house-standard mineral wool insulation into the walls, slabs, and flat roofs and optimized solar gain in winter. Natural cross ventilation and daylighting is optimized and pass through operable triple-glazed windows and doors.

Colorful aluminum cladding wraps around the building’s airtight envelope and thick CLT walls. The facade colors are echoed in the interior, as is a celebration of timber that is featured throughout. Natural lighting is optimized and complimented by LEDs. A biomass cogeneration plant provides heating and electricity for the radiant heating and cooling system, as do geothermal heat pumps and a heat recovery ventilation system. An extensive green roof covers the building.
