Back in November, I wrote about the F.O.O.L.I.S.H. Project:
F*&^%$# Obnoxious Ostentatious Luxuriously Irreverent Silly House
Mindy and I are doing something I NEVER thought I’d do; scrape a home and build a new one. Time for an update.
F.O.O.L.I.S.H. Project: Update!
This project started back in 2024. Mindy and I had purchased a decrepit home in a really great location. Our goal was to renovate it and then move into it eventually. It was about half the size of our current home, so it would be a good size space to live in post-kids. After much deliberation and planning, we scraped it and started over. Read the story here: https://www.1500days.com/the-very-big-f-o-o-l-i-s-h-project/
It’s been 140 days since I published the previous post and much has progressed. Here is what the home looked like back then:
And here is what it looks like today:
Here’s is what has happened since the last update:
Fancy Heat: To heat the home, I wanted hydronic floor heating. This is a system that uses warm water in PEX in to heat the home. The tubing is underneath the floor. However, hydronic systems are uncommon which makes it difficult to find an installer. I managed to get one quote and it was about $120,000. No thanks! I decided to take on the project myself. It took an immense amount of planning and a lot of labor, but I got it done for about $18,000.
I’m using an electric boiler which will use a TON of electricity (80 amp circuit!). But a huge photovoltaic array (24 x 450 watt panels) will more than offset my voracious electron consumption.
Energy Recovery Ventilator (ERV): This home is super tight, so I need a way to bring fresh air into the envelope. An ERV does this by continually exchanging air, but capturing the heat and humidity.
Similar to the floor heating, ERVs are obscure and expensive to have installed. I had someone ballpark the system at $40,000. The materials were about $15,000, so I saved $25,000 by DIYing it:
It was a fun job. A big part of the joy of life is solving puzzles. MMM calls it voluntary hardship. It was a lot of work figuring out all of my runs, but it was also very rewarding.
Windows/sliding doors: I don’t like noise. I also don’t like drafty homes that waste energy. For windows and sliding doors, I went with fiberglass, triple-pane windows from Alpen. Alpen is a local manufacturer that has a great reputation.
Rough electric: I had contemplated doing this myself, but am really glad I outsourced it. The electricians did a great job.
Rough plumbing: I had also thought about doing this myself and am glad I didn’t. It was a lot of work and the plumber was a pleasure to work with.
Insulation: I had a layer of foam sprayed to coat the envelope of the home. Then the cavities were topped off with fiberglass. The foam will make the home tight.
Deck: The home doesn’t have much of a backyard, but compensates with an expansive deck.
Cladding: The home is mostly stucco. But I’m also adding a PVC based product that looks like wood to the front facade. Real wood gets cooked here in the Colorado sun, so I’m avoiding that.
The Big Bad Heat Pump
Not everything has been great. I wanted a heat pump to provide cool air in the summer and also provide backup heat. A floor heating system takes a long time to bring a house up to temperature, so a mini-split system would be a great way to supplement the floor heat.
The system was installed back in January and still isn’t working. I won’t go into details because I’m not sure what went wrong. It could have been a mistake from someone who worked on the system or a lemon of a unit. But it’s been over two months and the thing still isn’t working. I’m out almost $30,000. I should have gone with a simple air conditioning system or used a more experienced installer.
What’s Left
Metal roof: This is going on RIGHT NOW. I just walked past the home and saw this:
We have hail here frequently which destroys asphalt shingles. I’ll never have to replace my roof. If the roof gets dented from hail, it doesn’t matter since you can’t see it.
A metal roof makes installing solar panels much easier. Instead of prying up shingles to install mounts, I can clamp them to the standing seam.
Solar panels: This home is all-electric. Because I’m DIYing solar, it will cost around $8,000 for the system. $8,000 is a small price to pay for a tiny utility bill ($20 monthly service charge) and free EV charging (we have a Chevy Bolt and a Tesla Model Y) forever.
Interior Painting: The home will be mostly white. Easy and simple.
Flooring: The home will be all tile. This is slightly weird for a Colorado home, but:
- I don’t like carpet! Yech! We’ll have rugs to make the home cozier and quieter.
- The tile will act as a big heat sink for the heated floors.
Trim: Simple design, painted white.
Kitchen and vanities: I would have been fine with IKEA, but Mindy wanted to go a little bigger. The home will have a mid-century feel, so the kitchen will look something like this:
Concrete: Driveways and a walkway.
Landscaping: Xeriscaping with some raised beds.
Big Money
We have spent about $685,000 so far. That’s a lot of money. However, Mindy and I will get a lot of joy living in this home for decades. I believe that in a couple of years when we reflect on the project, we will consider it money well spent. The home:
Has a floorplan that is efficient and pleasing. The kitchen, dining room and family room are one big flowing area. I don’t need a living room to put random souvenirs on display. The bedrooms aren’t small, but aren’t large either. You’re unconscious most of the time in a bedroom, so they are as big as they need to be and no bigger.
Is quiet. I don’t like noise. The triple pane windows will minimize noise from the outside. In the inside, many of the walls have mineral wool in the walls and a layer of sound absorbing material:
Is in a location that we love. We have a great community in Longmont. We also have a great group of friends in our little neighborhood. I’ve always thought that living in a great neighborhood is more important than the house itself. Here, we have both.
Has low maintenance systems. I’ll never have to paint the exterior or replace the roof. The boiler is a big resistor; much simpler than a modern, multi-stage furnace. I don’t want construction and home repairs to consume my life anymore.
Has one floor living. I love stairs now. Free exercise! In two decades, my knees may not feel the same.
Will be great for hosting people. We designed the basement to be a great guest area. It has two bedrooms, two bathrooms, a full kitchen, and a dedicated entrance. Good friends and interesting new people are frequently passing through town and we look forward to hosting them.
Will be great for travel. We will xeriscape the yard and have no grass. This will allow us to be away for long periods of time.
Big Joy.
I’ve always been fascinated about how things get made. Even as a kid, I loved walking through structures as they were being built. I paid no attention to Keep Out signs and explored freely. This was one of my favorite books as a kid and I still have it:
Designing and working on this project has been a joy and very fulfilling. It’s also really nice to work with skilled tradesmen who really care about their craft. I haven’t been so fortunate in the past.
I had deep reservations about building a home. But now that the finish line is in sight, it has been one of most fun projects I’ve ever worked on. I expect that when I’m old and decrepit, I’ll look back on this time with fond memories.
Amsterdam!
Mindy and I are taking a brief break from home construction and heading over to Amsterdam for a river cruise in early April. Let me know if you’re in the area or have any suggestions for us!
Life is good.
More 1500 Days!!!
You can also find me (and the dinosaurs) at:
- YouTube: My channel is mostly devoted to home improvement, but I have some other material coming up soon too.
- Instagram: Pretty pictures of dinosaurs, sunsets, and nail guns!
- Twitter: Spontaneous, often insane, ramblings
- Coworking space: On the surface, MMM HQ is a coworking space. Look a little deeper and you’ll see that we’re really building community. The members of MMM HQ are some of the finest people I know
- Buying a Tesla? Use my referral code to get some perks!












Wow, that is going to be a fantastic place! Also, 1500 address. coincidence?? 🙂
Have fun on the cruise, that sounds like a great time. We took local ones in Haarlem and Amsterdam which were really neat but never occurred to me to see the country that way. Maybe next time..
Matt-
I had AI change the address. Everything else is real though!
I’m sitting in Newark now, waiting to board our plane. Life is good.
A lot of great updates! The home looks beautiful and modern. So many things you have built for the future.
Have a nice trip. Enjoy river cruise.
Congrats on this house – followed your writing for a long time and this somehow feels like a “Final Thesis Project”. It’s nice to now have the experience to know what you and Mindy want in a house at this stage of your lives. We built a house year’s ago and in hindsight would have done so many things differently. Enjoy your cruise (did you bring those little dinosaurs along – lol)
Kevin!
Thanks for the kind comment! I like to think of the house as being the last chapter of a part of my life. I always say that though and then there is one more project.
Dinosaurs: Here they are, posting in front of the Rietveld Schroder home in Utrecht: https://www.1500days.com/wp-content/uploads/2026/03/PXL_20260331_085614615.PORTRAIT.jpg
I just build my first house with similar heating. Did the radiant heat DIY to save a lot and also did the heat transfer plates, got the idea from MMM a decade ago! We did electric heat pump too, sorry to hear about your trouble with it. Have you priced out electric air to water heat pump? they claim almost 3x efficiency of electric boiler. Also, any insulation ideas between the joist bays? was going to 2″ foam board as without insulation a lot of the heat transfers to the room (basement) below
I did look into an air to water heat pump. It would have heated more efficiently, but would have complicated a lot of other stuff and cost a lot more upfront, so I didn’t do it.
I did insulation between the joist bays too.
I’m loving the system so far, It’s really simple and works very well.
You’re a beast doing all that work yourself. Congratulations. Your new home will be beautiful and functional.
Thanks!
DIYing these few projects has been tremendously rewarding. Plus, it’s nice to get 25,000 in a day without trying!
Looks great! Interesting to read that hydronic floor heating, a heat pump and energy recovering ventilation is obscure in the US. I live in the Netherlands and these items are basically required to install by law if you are building a new home (to be precise: it is not required to install these items specifically but the isolation and ventilation requirements are so high that you basically cannot go without it).
I work near Amsterdam and grew up very close to Keukenhof. Let me know how much spare time you have in those places for any recommendations and/or would like to grab a coffee.
Best,
Geert
Geert!
It’s wonderful to hear from a native! I’m in Utrecht right now, but will be back in Amsterdam on the 8th and 9th. Please allow me to buy you a beer.
New home construction codes: Home construction and requirements are improving in the US, but are still pretty shitty. Our homes are under-insulated and often built to be disposable which is quite sad. I’m happy though to have a Brink ERV in my house!
Hope to see you soon, carl
Hey, congrats on the house project! I actually moved to Antwerp from the midwest US about 2 years ago, so I was shocked to see you’ll be passing through this week. If you want any suggestions regarding Antwerp or even Ghent, feel free to reach out. Enjoy the trip!
Hey Carl,
love to see how your house takes shape!
To me applying all these technologies in your house in the US by yourself makes you a real PIONEER.
Against all headwinds! You’ll love and enjoy all of it for many years to come.
Antwerp is beautiful, Monika was quite enchanted when we visited.
We found it crazy that there are NO bridges. Only tunnels!
Make sure to check out the ancient Sint-Annatunnel connecting both sides of the Scheldt.
And the Vlaaikensgang, a very old, cute, narrow walkway between some old houses.
The old Stock Exchange quite struck us and is well worth a visit, especially for FI folks. We liked to bask in the atmosphere there.
When we went there, there was a piano in the middle of this ancient hall and I could persuade Monika to play some classic symphonies on it. Lovely memories!
Excellent progress on the house project. I could see something like that 30K heat pump setback really throw a project off for someone on a limited budget. So nice to have a huge cash buffer when doing something like this. Cheers to your great home, may it give you and Mindy many decades of enjoyment.
P.S. Put in my early retirement request last Friday and hopefully it is approved and processed soon so I can spend time on working on big foolish projects, and maybe also take some river cruises.
Hi Carl,
It looks like a house that should cost 1.3 million so the money you spent was actually minimal I’d say. We have friends that just built an 1900 sq. ft. house in Phoenix in a gated community on a golf course, nothing special at all, and paid $930,000.00 and they still have to pay association dues and golf course membership so you got a deal. Looks very nice. Standing seam roof is the best, yes great for solar. Not sure about that air exchanger though, I’ve never understood why we make houses tighter and then have to punch holes in them so we can breath, ha. I am sure they will get the heat pump running, some of the newer models and more technical and like you say not all installers are up to date with current events. That is a nice spot you’re in. I wouldn’t be surprised if it appraised for close to a million next year.
Bob! Nice to hear from you! I’m still waiting until we meet again so that I can return your wayward vise grips:
Air exchanger: It’s much more efficient because it captures the indoor air temperature and humidity and transfers it to the incoming air. It also takes the place of bathroom fart fans and the kitchen exhaust. One really neat feature is that you can turn the temperature exchange off so that if functions like a whole house fan for cool summer nights.
I hope you come visit again sometime!
Love the look. Well worth it. Would love some details about this Thursday group hike I’ve heard you mention! (if it’s open to newcomers!)
I’ll send you a Discord invite so you can see the hikes. Should I use the email address you used to leave the comment?
