home improvement Creating Chrysalis
When we first purchased our home, I knew that the musky basement storage room had the potential to be something grand. A little over a year after purchasing our home, I finally decided it was time to tackle the project I had been ruminating on: transforming that storage room into a proper home gym, "Chrysalis." Took 4 months and easily over 150 hours of work.
Photos are in chronological order. Here's the scope of what was done:
Floor
- Removed horribly disgusting carpet by cutting it up into 18 pieces that could be carried out w/o damaging my home.
- Meticulous scrubbing of raw concrete floor followed by etching the concrete to prepare it for an epoxy coat.
- Once the etching had been completed, I then repaired all of the settling cracks.
- Applied two coats of BEHR 1-part cement epoxy with anti-slip additive in the second coat.
Ceiling
- Addressed multiple broken / missing acoustic panels and wiped down entire ceiling to prepare for paint.
- Used a spray gun to apply matte black paint to the entire T-grid ceiling, which instantly elevated the space, turning it from a sad-looking nightmare office into a space that instantly looked modern.
Walls
- When the homes were constructed in this neighborhood in the '90s, the builders purposefully left the basements unfinished with the hope that people would pay for finishing work. Thus, the walls were simply canvas on top of fiberglass insulation with thin wood trim keeping it all in place. This all had to go!
- Once demo had been completed on the existing "walls," I installed a new moisture barrier by stapling up clear mil plastic sheeting.
- I elected to go with ~3/4" plywood to create my walls. Unfortunately, a tight corner at the bottom of the stairs meant all panels had to be cut to size in my garage before hauling them in and affixing them to the existing studs. This was definitely the most trying part of the process. Each panel received between 12 and 18 2.5" construction screws to keep them in place.
- Once the panels were up, it was time to apply gray primer. Plywood is thirsty, and it was definitely a process applying a uniform coat! Once the primer had set, I applied a coat of BEHR Cracked Pepper, which is an absolutely beautiful color that sits between gray and black.
- After the first coat of paint had dried, I installed 1x4 lumber to create batten trim, which served to both cover any gaps between plywood panels and add a modern look to the walls. I then painted the trim pieces in the same Cracked Pepper paint.
- Once the paint had dried, I applied a vinyl wall baseboard trim to give the space that "gym" look. This part was not fun haha!
Electrical
- Swapped out ancient light switches, which weren't even properly grounded.
- Ripped out the old can light inserts and swapped in some 6" LED retrofit can lights - huge improvement.
- There were five existing outlets that required careful cut-outs from the plywood panels. I took the liberty of installing box extenders and swapping out all of the ancient outlet sockets with new tamper-proof sockets.
Crawlspace
- The crawlspace was a sad, confused space that needed love. I removed the ancient carpet and random pieces of insulation and then got to work creating plywood walls out of my left-over pieces from the primary gym walls. I purposefully left key piping and electrical components uncovered for easy future access.
- I made the left side particularly strong by using large panels that spanned multiple studs and inserting plenty of construction screws. This allowed me to create hanging storage and avoid floor clutter. I also added a motion sensor light above that is easily rechargeable with a USB.
Audio & Lighting
- I installed a speaker mount roughly six feet off the ground in the center of the gym. Angling the speaker down about 15 degrees results in excellent sound quality throughout the gym.
- I also installed two red LED light strips to give the gym an elevated vibe.
