Architectural freedom of design

Lightweight but very strong mounting profile

CHALLENGE

Straight lines, maximum light and a unique, remarkable design. This is how independent architect Lieze Vandael saw her own home. Due to the numerous voids and imposing windows up to 9 meters high, a traditional construction method was certainly not an option. A suitable alternative had to be found. Moreover, Lieze Vandael wanted to see the elegant, minimalist architectural style with straight lines envelop the building: a roof and façade finish in the same material - preferably timber - and moreover, seamlessly blending into each other. To have the building completely wrapped in wood. Definitely a real challenge! A neat and watertight connection between roof and façade is not an easy job at all. Besides, timber is never completely waterproof. So, the challenge for Lieze Vandael was to combine the roof and the façade into one uniform surface, ensuring a perfectly watertight roof.

SOLUTION

Architect Vandael wanted to step away from the traditional lightframe wood structure, and opted for an alternative mass timber construction: a load-bearing construction formed from tongue and groove stacked solid wood beams. After all, this type of construction creates a lot of possibilities and is, besides, a more durable and ecological solution. For the exterior finish of the building the architect chose thermowood Ayous, a knot-free, clear-grade exotic hardwood providing excellent durability. The façade was finished with thermowood in a traditional way. Finishing the roof, however, was a more complex task. Cladding a roof with timber, particularly a highly sloped roof poses a substantial risk. How to achieve a watertight roof?
