Introducing the Floathouse

A floathouse is a new kind of floating home designed to do one thing better than any other floating structure: to stay in one place, comfortably and securely, on the ocean.

Ventive SeaTech has pioneered new production processes that allow us to create incredibly strong tubular structures reinforced with a technology called filament winding, invented in the 1960's for the aerospace industry, combined with geopolymer cement to create incredibly strong, large-diameter tubes that are impervious to seawater and can withstand heavy wave activity.

Floathouse

The secret to the high wave-stability of the floathouse is the round hull-shape, very unlike a typical boat's hull which is deep and narrow, and the ability to connect two or more of the structures together. 

Two can be hinged together using pantograph arms, adding to their stability dramatically. When a wave comes by, pantograph technology will keep the floathouses very horizontal, rocking side to side very little, even as it slowly rises and falls on the waves. Occupants should experience this more as a gentle rise or falling sensation, a bit like riding on an elevator, with much less of the rapid side to side rocking motion that makes people seasick on a typical boat.

This anti-rocking mechanism is also aided by technology called a drogue, or a water-parachute, which is able to strongly resist rapid vertical-movement and rocking, further moderating any water-induced motion, increasing comfort and safety for home-owners.

The third thing making a floathouse much more stable than a typical sailboat is its heavy weight. Being made of inexpensive and environmentally-friendly geopolymer cement, the structure can be made much heavier than a typical boat of the same length. Waves therefore cannot lift it as easily, or toss it around like they can a sailboat, which makes a Floathouse much less responsive to wave conditions in general. A Floathouse can weigh as much as eight times more than a sailboat of the same length, and this is very good for its stability and comfort.

One Structure, Many Configurations

We offer the Floathouse shell in multiple configurations to suit a variety of needs. Each could be used in a variety of scenarios. Some, like the vertical Spar, are suitable for a rough, deep-sea environment, while others are more suitable for a calm marina setting with protected waters.

We currently offer the following products:

Limited pre-orders are available. Checkout our product overview for more information.

A Brief Look Into the Single Family Home

The standard Floathouse shell can be adapted to any number of private or commercial uses depending on how the interior is finished, but we expect one popular application to be the single family home that an average family of 4-5 people could feel quite comfortable in. Rather than seeing these structures as pleasure craft, we are building them to be your primary home year-round, and to last for decades without significant maintenance.

Here we see the basic shell, finished as a single-family home:

Shell - Single Family Home

Floathouse

The Floathouse structure is 80-feet long, 24-feet wide, and 24-feet high. It has 2 floors, giving a total floor-space of about 2300 square feet.

Windows on all sides offer generous views in every direction. The skylights illuminate the interiors in all rooms with natural sunlight. The structure's gently curving walls and ceilings are pleasing to the eye and give it an organic touch.

We've created a sample floor plan for a single family. Other floor plans are possible.

Top Floor - Single Family Home

Floathouse Floor Plan Single Family Home

The single family Floathouse has two entrances, a front and back door. The front entrance gives you access to the foyer. You can use the foyer to receive guests and store your shoes and coats. The foyer has a second door and is designed as a water-tight space that will prevent water from entering the rest of the Floathouse while the front-door is open.

The foyer leads into the living room and kitchen on either side, as well as downstairs-access. The living room is a bright and practical space. You can use it to relax in your favorite couch, socialize with friends and watch some TV.

Next to the living room are the dining room and kitchen. The kitchen has ample countertop space, cabinet space, a walk in pantry, room for a full-size refrigerator and stove, and a large island. You can sit around the island with your whole family, enjoy a nice breakfast and watch the sunrise.

After a good breakfast you can start your day at your home office. When you walk past the office you enter the hallway. This provides access two bedrooms and two walk in closets.

At the end of the hall you find the master suite. A large bedroom with ensuite bathroom. Here you can end your day with a nice warm bath or shower and watch the horizon.

Basement - Single Family Home

Floathouse basement

The stairs lead you to a generous garage space. You can turn this into a small workshop, laundry room or man cave. The garage has its own half-bath with a toilet and sink.

The other doors provide access to multiple water tight rooms separated by bulkheads. These rooms can be used for any number of things, from bedrooms to offices to storage rooms to home-aquaculture.

The rooms also function as a safety feature in case of damage to the hull which causes a water leak. The water will be contained in the room where the leak occurs and will prevent the Floathouse from sinking. Any two of these compartments can keep the entire structure afloat, giving more than ample safety-margin.

In the center are the gray and black-water storage tanks. The tanks will be able to hold up to a month of wastewater for an average family. By locating the wastewater tanks in the center of the Floathouse, we improve the balance of the structure and ensure that there is always access to the hull in case repairs are ever needed.

On the other end of the basement is the engine room. This can be used for an optional-engine and any other heavy machinery you may require. Otherwise it becomes available space.

The engine room also provides access to the power-center which contains space for electrical breaker boxes, electrical inverters, and battery power storage. We have designed this room to accommodate arrays of Tesla Powerwalls or lead acid batteries. Two to three Tesla Powerwalls should be enough to provide an average house with all the power they need for a full day. This room contains space for more then 10 Tesla Powerwalls. Batteries can be recharged via a generator, solar panels, or plugin power.
