Stone Basement Window Wells

The Design Goal

We always wanted a basement for our new house. The idea of building a new house on slab without one was foreign to us. Both my wife and I grew up in homes that had very active basement areas, with fond family and friend-related memories.

For both of us, basements were places to go for various games (board games, ping pong, pool, etc.), watching TV with family, a place for bulky exercise equipment, or just respite from hot summer sun.

And to improve the basement’s “livability”, we wanted it to have a 9′ ceiling height (we felt it made a big difference in our last house over a 7′ or 8′ ceiling), and large windows facing south.

We also thought that window wells that were more open and expansive could help draw in the sun, hopefully making the space feel less like a dungeon and more like normal living space (the window wells should have an additional side benefit, but I’ll explain that later).

After exploring the options, including this line of products:

Spycor window wells

We decided to go with real retaining wall cement blocks.

The Execution

In researching the Versa Lok product , I came across a series of interesting videos by Dirt Monkey on YouTube about retaining walls:

We like the long-term structural stability of the Versa Lok product, and it helps us achieve the Urban-Rustic look we’re going for.

We received several estimates, but decided to go with Poul’s Landscaping & Nursery since they had previous experience building these stone basement window wells. We paid a slight premium to do so, but part of that premium reflected their recommendation to use a concrete footing that would be tied into the foundation with rebar. Without it, they had seen too much movement on previous projects, creating future headaches and costly repairs.

Candido and Felipe set up the form for the concrete footing — got lucky with the timing of this shot — note the flying hammer and speed square.

After the guys set the rebar in the foundation through the Roxul, I stuffed the holes as much as possible with pulled apart Roxul Comfortboard 80 before they did their pour for the footings.

For color, we wanted a basic concrete gray, which we thought would complement our overall Urban-Rustic design look, in particular the eventual charred cedar siding.

Since firing our builder (there were two of them) in February, the job site has been quiet as I work alone, but then all of a sudden…

ComEd shows up with a new pole for our electric service, just as pallets of Versa Lok retaining wall block are delivered to site. The job site went from relative silence to hyperactivity — stressful, but also extremely exciting to see after such an extended delay.

On the next to last day, Felipe and Candido could’ve rushed to finish, but instead they came back for a few hours the following day to complete their work while also doing a really nice job of cleaning up — which we noticed and really appreciated. They even took the time to put back scrap plywood sheets that ran from the driveway to the front step so I didn’t have to.

Felipe has been working for Poul’s for 40 years (the company has been around for 50 years). Putting that into some kind of perspective, that means Felipe’s been doing this kind of work since the Jimmy Carter administration — that’s astounding.

Candido and Felipe make a great team: they seemed to really enjoy working together, they’re both diligent and conscientious, and it was fun to watch them do their thing — a mixture of back-breaking labor and skill.

Candido and Felipe — thank you for doing such a nice job!
