The interior projects delivered by Co van der Horst are tailored to the client's personality and lifestyle. Interior designer André Lammertsma designed this masculine project in Amsterdam Oud-Zuid. The living space houses a sturdy library in a deep black matte finish. With refined details such as the bronzed partitions, the reading desks and indirect lighting. The black wooden wall in the corridor, fitted with grooves, hides a blind door to the bathroom.
