Summit View Pop-Top Renovation
Project Overview
The homeowners needed more space to comfortably host family while taking advantage of their mountain setting. Prenvalley Builders built a second-story pop-top addition that added new sleeping quarters, an upper-level family space, and a balcony oriented toward panoramic mountain and Lake Dillon views. Working within the constraints of the existing structure, this project is special for how seamlessly the new second story integrates with the original home while dramatically improving livability and connection to the outdoors.

Our Approach
Prenvalley Builders approached this pop-top renovation with a focus on precision, coordination, and respect for the existing structure. By carefully sequencing construction and collaborating closely with the design team and trades, the new second story was integrated seamlessly into the home while maintaining structural integrity and build quality. The result is a high-performing addition that feels intentional, durable, and well-suited for mountain living.

Common Questions about Home Additions
-
It depends on the type of addition. If it’s a single story addition off the back of your home we can definitely accommodate that but just be wary that noise is a consideration if you work from home. For second story additions (pop-tops) we typically request that the clients live somewhere else due to logistical reasons with plumbing and electrical. It’s also a very invasive process with life safety considerations as well as just daily living comfortability issues.
-
This can vary quite a bit on size but we’ve seen these projects range from 4-6 months in design/ plan review and 5 to 8 months in construction. You can consult our process sheet here!
-
Make sure to get an asbestos report early on to ensure that you or the construction team won’t be exposed during the project. Also, asbestos remediation can be expensive so that additional cost is good to know early on. Also, additions can be unpredictable - especially in older homes. Check if your contractor has considered all factors of the project (e.g. lath and plaster walls, unlevel floors, structural considerations, age of existing plumbing and electrical, etc.). Making sure your contractor is carrying a contingency budget on an addition is especially important because we typically don’t know what we’re going to find behind walls and floors until after demolition has been completed which can add additional cost.
