Luxe Home Renovation: Hidden Hydrofloor Pools

Hydrofloors have become the latest’s in lavish home renovation, equipping modern mansions and sprawling family homes with multi-use spaces that give way to secret underground pools.

(We can dream, can’t we?)

Hydrofloors, which are basically movable pool floors that can be lowered down to variable swimming pool depths or raised to meet the surrounding ground and used as a flat-top surface, have made the seamless transformation from a pool to a terrace or indoor gym to lap pool possible at the touch of a button.

The Hydrofloor Design Engineers at Twinscape Group who specialize in unique architectural solutions to maximize the utility of space say that aesthetically, Hydrofloors are a design dream since they are pragmatically strong, safe, and energy efficient. Not to mention a highly unique talking piece when visitors take the tour of your maison.

The immense load capacity of trademark Hydrofloors can accommodate any floor finishing (i.e. tile, glass-mosaic, and even marble), exceeding, while in its raised position, the standard floor strength rating of a home to support 55 lb/ft. So don’t fear turning your shimmering lap pool into a cool party space for celebrations. The Hydrofloor structure itself is made of stainless steel beams and custom designed to fit your unique pool size and location; outside or inside, it’s up to you.

Standard Hydrofloors (about 12’ X 24’) run approximately $230,000 (the starting cost for a Ferrari 458 Spider), but before you let that number soak in, a good excuse to take the plunge is that they’re highly energy efficient compared to average pools. The ability to ‘cap’ these disappearing pools helps maintain water warmth during colder months and keep it cool in the peak of summer.

And how the heck do they work? A buoyancy structure beneath the stainless-steel floor plates is pulled down via a network of stainless-steel cables and a pulley system with a water-based hydraulic cylinder to the pre-programmed depth, according to Twinscape engineers.

For safety precautions, a water level sensor is installed beneath the movable floor. And making the switch from floor to pool and back again is literally easier than scrolling through Netflix, being controlled by an up, down, and stop key-switch control button or touch pad.

Moving floor pool - party in and on the pool!

“Today’s modern man doesn’t want to be ‘the pool guy,’ constantly scooping leaves out of the water and having to worry about the safety of an unattended pool,” says Jim Farrell, Twinscape Group Business Development Director for the US. “Throw a great pool party, and then entertain friends on a beautiful terrace – all in the same space! Having a beautiful pool when you want one and, (at the touch of a finger), not having one when you don’t is what makes the Hydrofloor so awesome.”

So toss out that raggedy leaf collector and useless underwater vacuum, since a Hydrofloor investment comes with annual visits from certified Hydrofloor technicians. And now that you understand the logistics, the real question is how imaginative can you get with where you put your Hydrofloor and what it transforms to lowered and raised.

Beginner’s guide to cigar shapes and sizes — and why they matter
Why your cigar choice says more about you than your watch (and how to pick the perfect one)
A collection of cigars

Walking into a cigar shop and facing what seems like a million options is enough to make anyone panic. Cigars stacked everywhere, each with a strange name, size, and a slightly different shape from the last one. If you haven't done this before, it's tempting to just grab something, anything, and run!But hold on a second. Those shapes actually matter. They aren't just there to look fancy or make things confusing. The size and shape change the whole experience of smoking that cigar – how it tastes, burns, and feels. It's kind of like how driving a tiny sports car is way different than driving a big truck. Both get you where you're going, but the experience along the way is not the same.

Every new Game of Thrones spinoff explained
George R.R. Martin's television world continues to grow
Matt Smith starring in House of the Dragon

When it first aired on HBO in the early 2010s, Game of Thrones dazzled audiences with revolutionary special effects and terrific acting in a unique fantasy world. Based on author George R.R. Martin's series of novels, the universe depicts the battles between several different noble families as they try to climb to the top of the continent of Westeros, both politically and figuratively. The war scenes, family drama, and massive number of characters helped make the story feel fresh and new every time a new episode aired.

As Martin's attention shifted to television and away from his books, fans have looked to the TV series to finish some of the stories he couldn't finish on the page. Game of Thrones left fans wanting more, despite its poorly received finale, and a plethora of spinoffs are on the way. House of the Dragon already has two seasons completed, and there are several others in the coming years to look forward to.
House of the Dragon
House of the Dragon finished its second season in 2024. The show chronicles the heated family dynamics of the Targaryen empire almost two centuries before the events of Game of Thrones. The third season should pick up the civil war between Queen Rhaenyra's forces and King Aegon's after a slow-building conflict throughout the second act.
