Over the Edge

About this project

General overview

Perched on the western slope of 8,300-foot Andesite Mountain, East Coast owners aptly named their Big Sky home “Over the Edge.” Custom-designed with horizontal windows spanning 50-feet at times, the home connects those on the inside directly with their mountainside location.

Constructed from refined fir timber and weathered Montana fieldstone, the owners consciously employed sustainable materials, securing a LEED Silver Certification. The home’s fir, pine, and white oak interior are warmly lit by light that streams through the abundant wall-to-ceiling windows. Even the 40-foot tall staircase tower winds upwards against a wall of windows, offering stunning views of Eagle Rock, Pioneer, Cedar, and Sphinx Mountains.

The four-story floor plan features special locker rooms for ski and fishing gear and a spa that gives outdoor enthusiasts a place to unwind. The use of locally sourced materials creates a natural mountain refuge where owners can escape from their busy city life with family and friends. While the home celebrates its rustic location, its structure and interior design emphasize the comforts of modernity.

"We have a very good relationship with the OSM team who built our home, Todd Smith, Cass Bolton, Le Fannin and others. They have a thorough understanding of the process from planning to execution and a great respect for the architect. Communication between OSM, Acanthus Architecture, and our family made the process comfortable and smooth. Everyone who has visited our home has been incredibly impressed with the quality and attention to detail. The overall quality, fit and finish of our home exceeded our expectations. Over the years we have recommended OSM to several friends and associates; we were pleased to hear they also had a great experience."
