Expand Without Moving. Upgrade Without the Hassle.

Adding to your home isn’t just about space — it’s about purpose. Your home should grow with you.

Running out of space? Love your neighborhood but need your home to grow with you? A custom home addition is the smart, affordable way to add square footage and functionality, without starting over.

At Niesen Construction, we specialize in seamless home additions that look and feel like they’ve always been part of the original house. Whether it’s a new bedroom, second story, extended kitchen, or an entire in-law suite, we’ll help you design and build exactly what you need, on time, on budget, and stress-free.

‍

Why Build a Home Addition?

  • Avoid the Cost of Moving: Stay in the location you love but with more room.
  • Add Real Value: Smart additions can significantly increase your home’s value.
  • Custom Fit: Tailor your home to your lifestyle, new bedrooms, expanded kitchens, sunrooms, etc.
  • Stay Put, Level Up: Perfect for growing families, new hobbies, or multi-generational living.

Many homes in Austin’s older neighborhoods weren’t built for modern needs. A thoughtful addition can make your house finally feel like home
