Dave and Mary Spellings’ Palapa Pineapple Taking Shape in Belize

Interior construction is underway for Dave & Mary Spellings’ Monolithic Dome home—the Palapa Pineapple—in Belize. Dave Spellings said he got the idea about 25 years ago when he visited Ivan Sheinbaum’s Xanadu Resort on Ambergris Caye in Belize. “I wanted a smaller, more unique shape, with one room on top of the other. I squeezed the dome into the shape it’s in.”

The result is a tall, prolate ellipsoid shaped Monolithic Dome with multiple windows that create a unique “pineapple” look. It is five levels tall and features a rooftop patio overlooking the ocean.

“I’m a retired surveyor, with some civil engineering,” said Spellings. “I had difficulty in sketching it in 3D, so I built a 1/10 model with wood blocks—about the size of cinder blocks—that I had experience laying.”

“I put all the floors together,” he said. “Painted it with deck paint to help preserve it, then blew it with my leaf blower just to see how it held up! It didn’t budge!”

Dave and Mary planned to build the home on Caye Caulker, Belize, after discovering the island years earlier. “We turned it into ‘our island’ when we found a property on the north side,” he said.

Working with Larry Byrne, retired designer at Monolithic, they came up with a workable design.

The 25.5-foot diameter ground floor is entirely open with four large archways. They added custom gates to each arch. The large openings and clear plan allow storm surge to pass through—underneath the living areas—during a hurricane.

The 27-foot diameter main floor includes the kitchen, utility, bathroom, and living room. The third level is the bedroom with shower, closet, and bath. Half of the room is open to the living area below.

The fourth floor is a 23-foot diameter office/loft.

And finally, the fifth level they call the “scenic area.” At 16-feet diameter, it’s effectively a 180 square foot patio with a beautiful, 360-degree view of the island and the Caribbean Sea.

“After years of planning, research, and prayers we got electric on our side of our Island and a reputable local contractor,” he continued. “An electric meter pole and water meter were installed, 8 by 18-foot concrete piers were set and a 26-foot concrete ring foundation was poured in June 2018.”

Monolithic and Spellings loaded a 20-foot container with windows, gates, scaffolding, compressor, polyurethane foam, tools, and everything they thought they needed the job. The Airform and a concrete pump were shipped separately because the container “was packed to the gills.”

Today the Monolithic Dome shell is complete. Dave and Mary are working on the interior structure.

“Many trials and tribulations later … we are in phase three of constructing floors,” Dave said. “Hopefully, and prayerfully, we will have a Pina Colada move-in party by the summer’s end.”
