Featured Projects


Valley Insurance

The Valley Insurance project is a 15,000 square foot gut and interior remodel of an office space for the incoming building owner/tenant who would be occupying just over half of the vacant building. The result is a beautiful office space that has private offices, shared office space for 30 employees, a workout room, locker rooms, and an owner’s suite with master bathroom, shower, and closet space. The modern style, beautiful reception desk, finished radius soffit, and employee amenities provide a welcoming and comfortable space for Valley Insurance’s clients and employees. The owner wanted to make use of the additional available ceiling height in the open office area. Sequoia General Contracting developed a plan to raise the existing HVAC, electrical, and sprinkler to gain over a foot of additional height giving the office area a much more open feel.
