Home Additions & ADUs
Need more room? We add on to your home or build a separate ADU — a great fit for family or rental income.
Sometimes you love your home but need more space. Trammel Design adds the room you need. We build bedroom and family-room additions, second stories, and full accessory dwelling units (ADUs).
An ADU is a small, separate home on your property. People here use them for parents, grown kids, guests, or rental income. We make sure the new space fits your home and meets Crook County rules.
We tie the new work into your roof, siding, and power so it looks like it was always there — and we build it for our cold winters and hot, dry summers.
Why choose Trammel Design?
- Fully licensed and insured for your protection.
- Upfront pricing you approve before any work starts.
- Serving Prineville, Powell Butte, Redmond, Bend, Terrebonne, Madras and surrounding areas.
FAQ
Home Additions & ADUs — common questions
Can I build an ADU on my property in Prineville?
Often, yes. Trammel Design builds ADUs across Prineville and Crook County and handles the permits. What you can build depends on your lot, so we check your property rules before we start.
Will a home addition match the rest of my house?
Yes. Trammel Design matches your roofline, siding, and finishes so the addition blends in. From the street, it should look like part of the original home.
