"The division of the new dining room into two separate function areas created by the NanaWall harmonizes perfectly with the character and detail of this fine old building.”
Erling Falck
"The NanaWall system was key to creating a flexible floor plan to host a variety of events in type and size. It enabled us to seamlessly connect the exterior spaces to the interior, providing guests with a memorable experience."
- Robert Wallis, Williams + Paddon Architects + Planners
“Fantastic. Incredible. Best opening wall system I have ever seen. During the winter months there is not even a hint of cold air flow. The system opens and closes effortlessly.”
