Local residents are enjoying the years of planning and work put in to improve the well-being of the community offered at the Reeves County Recreation Center. The facility began as an idea among the county commissioners in early 2012. Though elected officials changed over the years, each court has had at least one torchbearer who refused to let the dream lose momentum.

CTV News recently featured a Monolithic Dome home in Saskatchewan, Canada. Tonia Vermette constructed the home 18 years ago, and it’s a wonderful place to live, but as an artist, she never seemed to be finished with the house. Over the years, she’s painted murals, vines, and textures on the walls, turning the home into a living artwork.

Sunset at Arcadia Dome Home in Providence, Utah

Thirty people toured our house — Arcadia Dome Home — during the annual dome tour on October 15, 2022. Most visitors came from Utah or southern Idaho, but some came from as far away as Colorado. They didn’t come empty-handed. They had ideas, sketches and questions about building their own dome home. So. Many. Questions.

Prepare for real-world emergencies — not doomsday

When the Dallas Observer wrote about the Monolithic Dome Research Park, they connected the domes to prepping for doomsday. That misses the point. We are not preparing for the end times; we are preparing for the end … of a good book, curled up on the couch, peacefully reading while a storm rages outside.

Throwback: Our Monolithic Dome home on a hill

The setting sun lights Arcadia Dome Home.

While writing about preparing for real-world emergencies, I realized there is virtually nothing about our home, Arcadia, on this website. We built the home six years ago and posted several great stories on monolithic.org with pictures of its design, construction, and completion. It’s time to migrate and update the articles.

Photo tour of Hawaiian dome home

Hawaiian dome home for sale.

Back in 2020, Jo King listed her Hawaiian home for sale. Needless to say, selling a home during a pandemic proved more than a little challenging. Instead, she pulled it from the market. Now she thinks it’s time to try again. Her Monolithic Dome home is in one of the most beautiful settings we have ever seen — on the island of Kauai.

Hard math, made easy, when calculating a horizontal ellipsoid

Orthographic sketch of design ideas used in the new horizontal ellipsoid calculator.

What are the areas and volume of a horizontal ellipsoid dome? There isn’t an easy answer. Spherical domes have well-defined formulas. Vertical ellipsoids are symmetrical. But tip an elliptical dome on its side and measuring it gets a whole lot harder.

The small town of Spencer, Wisconsin, dedicated a new Monolithic Dome gym and arts facility this past weekend. The dome was part of a $5.9 million upgrade to the high school with FEMA providing $2.9 million as a grant to construct the dome as a shelter-in-place facility during severe weather.

Throwback: Why Avalon chose a Monolithic Dome gym

Aerial view of the Avalon gymnasium.

Twenty years ago, the school board in Avalon, Texas, broke ground on a new Monolithic Dome gymnasium. It would be more than just a place for playing ball, it became a classroom, concert hall, community center, and — when necessary — a storm shelter. No wonder it’s called the Avalon Multipurpose Center.

Throwback: The world’s oldest monolithic dome — the Pantheon

The entrance to the Pantheon in Rome, Italy.

The Pantheon is arguably the first monolithic dome. Not in the sense of the modern, insulated structure, but as the original one-piece, monolithic, concrete dome — the largest unreinforced concrete dome in the world. No other significant structure of antiquity has survived as well preserved nor with the roof intact.

Throwback: Houston area church is a dome of many firsts

Flying over the job site reveals the scope of work.

Today’s throwback story is from 1984 with a dome of firsts — the Maranatha Church — the first Monolithic Dome over 200-feet diameter, the first dome proving energy savings enough to pay for the building, and the first high capacity auditorium with seating for over 4,000.

The South’s say goodbye to the South Sawmill Lodge

South Sawmill Lodge

It’s time to say goodbye to the South Sawmill Lodge. Randy South’s family of South Industries started the 90-foot diameter dome in 2009 on the old family homestead in Island Park, Idaho. Over the next four years, the family squeezed in time to finish the dome which became a lodge and reunion center rented out to dozens of families over the years. The lodge sold this spring.

The easy way to calculate a dry bulk storage dome

Medium product storage dome.

How big is a Monolithic Dome that stores 10,000 tons of ammonium nitrate? Or 750,000 bushels of corn? Or 34,000 metric tonnes of gypsum? These are straightforward questions without quick answers — until now.

The dome builder workshops are back!

Workshop alumni after building a Monolithic Dome.

It’s back! After a year and a half hiatus, the Monolithic Dome Builders Workshop resumes again in September 2021. Coronavirus restrictions are lifting. Travel is returning. We can finally gather to teach, discuss, and build another Monolithic Dome.

Over the edge with vertical ellipsoids

Sketch of the concepts used in the vertical ellipsoid dome calculator

Inflatable shapes are the basic components of Monolithic Dome design. If it inflates, it can be constructed … probably. There are two primary shapes that dominate dome design — the sphere and half-ellipsoid. However, these are not the whole design palette. Sometimes we need to go beyond the basics. or in this case, beyond half of the ellipsoid.

Rare winter storm wreaks havoc in Texas

Winter snow covering Monolithic Dome Research Park near Italy, Texas

Monolithic Domes are amazing. The insulation, coupled with the concrete’s thermal mass, creates an atmosphere that is hard to describe. Simply put, it feels the same today as it does in the middle of summer. If you set the thermostat at 70 (21°C), it just stays there. During the two-degree, 24 hour period, my heater ran for a total of 9 hours. This is a small heater, with only 30,000 BTUs. Most homes the size of mine have 100,000 BTU heaters, but even my neighbors with electricity struggled to stay warm with heaters running nearly 24/7.

Refactoring the ellipsoid calculator

Sketch of ellipsoid dome calculator concepts

Circles and spheres are easy to measure. Calculating a spherical dome’s floor area, surface area, perimeter, and volume are straightforward mathematical formulas. When I wrote the new Spherical Dome Calculator, the challenge was the scaled drawing, not the computed values. Ellipsoids — on the other hand — are hard.

Another workshop canceled due to the coronavirus

Workshop canceled again

We are a year into the pandemic and although the daily news is bad, we have every reason to hope. Two vaccines are approved and more are coming. With every person vaccinated we inch closer to a return to some form of normal life. Patience is required. We would love to start holding the Monolithic Dome Builders Workshop again, but it’s not yet time. For the sake of our customers and staff, the Spring 2021 Monolithic Dome Builders Workshop is canceled.

TBT: Design inspiration in a frozen hotel

Art Suite at Ice Hotel in Sweden

In today’s Throwback Thursday we revisit the Ice Hotel — 200 km north of the Arctic Circle in Sweden. This unique hotel is built and rebuilt every winter using ice, snow, and a lot of creativity.

TBT: The past and future Johnson Creek School

Aerial view of construction

Today’s Throwback Thursday is a bit different as we look to the past and the future in Johnson Creek, Wisconsin. In 2016 the Johnson Creek School District opened a five-dome school to serve as the combined middle and high school. The small district of 750 students was dealing with old school buildings plus a hodgepodge of additions and portable classrooms. The maintenance costs were increasing and they needed something new. They tried several times to pass a bond to build a conventional school, but each time the voters rejected it. So they sought for a more innovative, affordable solution and found the Monolithic Dome.

The story of a Hawaiian dream home — now for sale

Whoever buys Jo King’s Hawaiian dome will buy so much more than a home. They’re buying a dream. The dome has a lot to offer, starting with breath-taking views. Snuggled on an acre of land in the Waimea Valley on Kauai, it’s surrounded by an abundance of history and natural beauty. The open floor plan offers two bedrooms and two and a half baths upstairs with another bath as well as two outdoor showers downstairs, all covering about 1,700 square feet. Painted coconut palms adorn the concrete walls, and a large lanai takes full advantage of the scenery.

Monolithic Dome workshop graduation photo

We live with hope for a better future, yet, we need to recognize the realities of today. COVID-19 cases are surging in Texas and across the US. There is no reason to believe the coronavirus pandemic will end anytime soon. We must accept that this is our new “normal” and plan accordingly. To that end, we are canceling the Fall 2020 Monolithic Dome Builders Workshop.

TBT: The Lincoln County Farm Center
