What Is a Second Story Addition?
A second story addition adds a new level on top of your existing home. It creates more living space, such as bedrooms or baths, without using more of your lot.
Because the new level sits on the home you already have, planning starts with the existing structure. For a broader look at additions, see our guide to home additions.
What Should You Consider Before Adding a Second Story?
Before you build up, think through these five things, because each one shapes the design of your addition.
01
The Existing Structure
The foundation and framing have to support the new level, so the structure is evaluated first.
02
Stairs and Layout
Plan where the stairs go and how the new level connects to the floor below.
03
Roofline and Exterior
The new level should match the style of your home from the street.
04
Systems
Heating, cooling, plumbing, and electrical are extended to the new level.
05
Living During Construction
Think through how your family will live in the home while the work is underway.
Who Should Add a Second Story?
A second story suits homeowners who need more bedrooms or living space but want to keep their yard and stay in their neighborhood.
It is often a good fit when a lot has limited room to build out. Local permitting and neighborhood character shape what is possible, so they belong in the conversation early.
How Much Do Second Story Additions Cost?
Cost depends on the size of the new level, the condition of the existing structure, the roofline, and the level of finish. Structural work, extending the home’s systems, and local permitting move the number most.
The best way to get an accurate number is to talk through your project with us.
What Are the Benefits of a Second Story Addition?
The main benefits are more space without a larger footprint, a yard you keep, and a home that still fits your neighborhood.
- More space, same footprint: Add rooms without using more of your lot.
- Keep your yard: The new level sits on the existing home.
- A design that fits: The addition matches the style of your home and the street.
- Clear communication: You hear from us at every phase.
Second Story Addition vs Building Out
You can add space by building up or by building out. Building up adds a level, and building out extends the home along the ground.
| Second story addition | Building out | |
|---|---|---|
| Footprint | Stays the same | Grows |
| Yard | Kept | Partly used |
| Structure | Builds on the existing foundation and framing | Adds new foundation and framing |
| Best for | Lots with limited room | Lots with space to expand |
The tradeoff is that building up depends on what the existing structure can support, so ask early what your home allows.
