What We Do in a Second Story Addition Project
Adding a full second story is one of the biggest transformations a home can undergo. Our team manages every step—from design and structural planning to finishes and final walkthrough. Here are some of the most common upgrades and spaces we create in a second story addition:
New Living Quarters
Expand your home with additional bedrooms, ensuite baths, or a full family bathroom upstairs.
Design a spacious, private master suite with walk-in closet, spa-style bath, and sitting area.
Add upstairs family rooms, playrooms, or entertainment spaces tailored to your lifestyle.
Home Offices &
Studios
Create a quiet, dedicated workspace or hobby area with plenty of natural light.
Seamlessly connect your new level with custom staircase design that fits your home’s style.
Ensure your home is built to last with proper foundation support, roofing, plumbing, and HVAC extensions.

From exterior siding and windows to interior flooring and trim, every detail is chosen to create a seamless transition—inside and out.
