A+W Lausanne

The highly technical nature of construction now requires not only leading edge knowledge in varied sectors, but also the skills and knowhow to coordinate different fields so as to produce solutions that are not only technically, but also economically optimum.

Customers and investors can also achieve, without additional costs, gains in productivity, comfort, functionality, safety and respect for the environment.
Since 1999, we have offered our customers planning and consultancy services for all building techniques.
