Running out of space but love your neighborhood?
In Denver’s tight lot market, building up instead of out is often the perfect solution. A second-story (or “pop-top”) addition gives you an entire new level of living space without sacrificing yard or character.
At AAA Home Improvements, we’ve spent over 20 years engineering second-story additions that look like they’ve always been part of the home — not an afterthought.

What Is a Second-Story Addition?
A second-story addition adds an entire new floor above your existing home. Depending on structure and zoning, it can include:
-
Primary suites with mountain views
-
Children’s bedrooms and bathrooms
-
Loft offices or bonus rooms
-
Laundry rooms and storage
Denver calls these projects “pop-tops” because the original roof is removed, then a new level is framed above existing walls and structure. It’s complex work — but with AAA’s design-build process, it’s seamless from concept to completion.
Why Build Up Instead of Out?
Maximize Your Lot
Many Denver neighborhoods — Wash Park, Berkeley, Highlands — have small lots and strict setbacks. A second story gains space without violating those limits.
Preserve Your Yard
Keep space for kids, gardens, and outdoor living instead of building into it.
Add Panoramic Views
Elevating living space brings Front Range sunsets right into your primary suite.
Increase Home Value
A two-story home in Denver often appraises 20–30 % higher than a ranch of similar footprint.
Stay Rooted
You keep your lot, school district, and equity — while transforming your home for the next chapter of life.
Design & Engineering Considerations
Structural Feasibility
Adding a floor requires verifying that the existing foundation and load-bearing walls can support new weight. AAA’s engineers conduct core samples and structural analysis before design begins.
Stair Placement
Stair location is key for flow and code. Our design team integrates stairs as a feature — not an afterthought.
Plumbing & HVAC Routing
Second-story bathrooms and laundry require careful vertical runs. We re-engineer systems for efficiency and balance.
Roof Line Integration
A properly designed roof transition is what makes a pop-top look original. We match pitch, soffits, and materials perfectly.
Permitting & Zoning
Each municipality has height restrictions and side-yard requirements. AAA handles the entire permit process and city submissions.
Second-Story Design Inspiration
| Style | Description | Distinguishing Feature |
|---|---|---|
| Modern Farmhouse | White lap siding + black windows | Vaulted ceilings, front gable |
| Transitional Pop-Top | Blends brick main floor with fiber-cement upper | Neutral palette, clean lines |
| Classic Denver Bungalow | Adds dormers and clad windows to match original | Historic charm preserved |
| Contemporary Mountain | Steel and glass accents | Open balcony and view walls |
