The Feature That Defines Our Cabin
When most people first see our A-frame cabin, one feature immediately catches their attention.
The glass wall.
It completely transforms the interior, filling the cabin with natural light and creating an incredible view of the surrounding forest.
Although it looks like one massive window, it's actually a commercial storefront system that I designed and built myself.
Because I've worked in the commercial glass industry for more than two decades, I was fortunate to already have the tools and experience needed for a project like this.
While this approach won't be right for every cabin, I wanted to share how we built ours and some things to consider if you're thinking about incorporating large glass into your own design.

Why We Chose a Glass Wall
One of our goals from the beginning was to blur the line between the cabin and the outdoors.
We didn't want to feel like we were looking through small windows.
We wanted the forest to become part of the cabin itself.
The floor-to-ceiling glass completely changed the feel of the space.
It made the cabin seem larger, brighter, and more connected to nature.
Looking back, it remains one of my favorite design decisions.

Using Commercial Storefront Glass
Rather than using residential windows, I chose a commercial storefront system.
Storefront framing is designed to support large sections of glass while maintaining clean, narrow sightlines.
One of the biggest advantages for our project was that I already had access to leftover storefront framing and doors from commercial jobs.
Over several months I saved usable pieces that eventually became the front wall of our cabin.
That dramatically reduced the overall cost of the project.
If you don't work in the glass industry, purchasing a complete storefront system will likely cost significantly more than standard residential windows.
Designing the Wall
Although the front wall appears simple, fitting a rectangular storefront system into a triangular A-frame opening required careful planning.
Every measurement had to be exact.
Because of the angled roofline, every piece of framing had to work together precisely.
In fact, this was the first triangular storefront system I had ever built.
Even after years in the commercial glass industry, it challenged me.
Fortunately, the extra planning paid off.

💡 Jim's Tip
Large glass leaves very little room for error.
Measure everything more than once before ordering or cutting materials.
It's much easier to spend another hour measuring than replace expensive glass later.
Installing the Glass
After the framing was secured, we returned a couple of weekends later when the insulated glass units arrived.
The installation itself went surprisingly smoothly.
One of my favorite parts of the day was teaching my family about the work I've done professionally for most of my career.
Sharing that experience together made the project even more rewarding.
By the end of the day, our cabin had been completely transformed.
Instead of looking at plywood sheathing, we were looking through an incredible wall of glass into the surrounding forest.
It was one of those moments that made all the hard work worthwhile.

Is a Glass Wall Right for Every Cabin?
Not necessarily.
Large windows come with tradeoffs.
Advantages
- Incredible natural light
- Beautiful views
- Open feeling
- Modern appearance
- Excellent connection to nature
Considerations
- Higher cost
- More complex installation
- Energy efficiency depends on glass selection
- Requires careful planning and precise framing
For our cabin, the advantages far outweighed the drawbacks.
I would absolutely build it this way again.

Lessons Learned
Looking back, I'd recommend:
- Plan the wall before framing begins.
- Measure everything multiple times.
- Don't underestimate the complexity.
- Buy quality glass.
- Think about energy efficiency.
- Consider your climate.
A glass wall becomes the centerpiece of an A-frame cabin.
It's worth taking your time to get it right.
