A post-and-beam mountain home addition shaped around view, structure, solar orientation, and respect for the original design.

Set among Jeffrey pines and positioned on a knoll above Floriston Pass, the existing residence already had a strong relationship to the landscape. The challenge was to expand it without making the addition feel like an afterthought.

MASTRIDICASA was asked to help add bedrooms, a guest en-suite, loft flex space, storage, a new deck, spa patio, and updates to the surrounding property while preserving the character of the original Dennis Zirbel post-and-beam home.

As the design developed, one priority became clear: the addition needed to open itself to the northern view. The solution was a two-story glass view corridor that brings sky, trees, and distant ridgelines into the experience of the home.

That decision shaped the rest of the work. Solar studies helped determine roof overhangs for seasonal comfort. Structural coordination helped realize the glass wall with minimal steel and limited retrofitting. Title 24 coordination helped balance energy performance with the design intent.

The result is an addition that feels deliberate, connected, and quietly ambitious — open to the view without losing respect for the home that was already there.
