Lake Erie Residence

The four-season open-air porch was designed to maximize views of the lake, yet the tightly sealed operable glass walls keep the interior warm and draft-free in the winter. In the summer, NanaScreen protects against mosquitoes and moths.

River House Retreat

For homeowners who frequently entertain family, friends, and business associates, transforming the great room to host 120 people was a key priority. Opting for a cero sliding door, the space now facilitates an indoor-outdoor space.

“Our ambition as architects for this home was not simply to frame the view but to become one with the landscape. The NanaWall system achieved this in one elegant and dramatic gesture.”
