Starting around 18,000 years ago, when the last ice age began receding, sea level has risen by about 400 feet. The National Climate Assessment forecasts a rise of up to 4 feet by 2100. Floating home living may soon be a necessity.
There are two types of floating homes:
- Permanently-floating homes in lakes and other waterways.
- Homes that float only when flood waters swell, but sit on the ground during the dry season.
Requiring the latter on new construction within floodplains, and considering same for threatened shorelines, is one way to plan for the future. Although floating homes near the coast need protected waters, wave walls and dykes (as used in Europe) are a future possibility. Inaction is costly. Some inspiration for those on the water:

On The Mississippi
The easiest homemade solution, foam blocks under your home. The 4 guide posts keep the house in place as it rises, just like a floating dock. buoyantfoundation.org
Dr. Elizabeth English of the Buoyant Foundation explains the necessity of buoyant homes. A steel frame that holds the flotation blocks is attached to the underside of the house. There are four ‘vertical guidance’ poles not far from the corners of the house. The tops of the poles are attached to the steel frame. The poles telescope out of the ground, allowing the house to move up and down. Please visit buoyantfoundation.org

You never know what’ll pop up here. Sometimes it’s boats that don’t look like floating homes at all, other times a legitimate house boat will come up. Worth checking back if only to indulge your dreams.
Or do some research in case the perfect home ever floats your way:
The Float House
Designed by Morphosis Architects and students from UCLA collects its own water, generates its own electricity, and is capable of floating as high as 12 feet on rising flood waters. Flotation is made possibly by a single unit of expanded polystyrene foam coated in glass fiber reinforced concrete. The panelized walls, windows, interior finishes and kit roof are prefabricated and assembled on-site. The screens slide in front of glass for hurricane winds. Brad Pitt’s Make It Right Foundation, which is dedicated to building affordable and green housing for New Orleans residents displaced by Hurricane Katrina, has built 50 LEED homes in New Orleans Lower 9th Ward so far, with 100 more under construction. He has built them all for under $150,000.

Maasbommel, The Netherlands #1
The Dutch have realized that building higher dikes to keep out the sea is no longer the solution. Here’s a community of 37 homes near the Maas River dyke, a river which is known for its seasonal flooding. These homes cost less than 5% more than the cost of conventional construction. Picture above is during a swell. Designed by Factor Architecten
Amphibious homes that rest on land but are built to rise when waters rise. When the river swells the house will float as much as 18 feet. It floats back down as the water subsides. Designed by Factor Architecten
Houses sit on hollow concrete foundations that are attached to six iron piers. The fat posts in between the houses are the guides that keep the homes in place as they glide up and down. Factor Architecten

On the Fraser River. There are 500 floating homes in San Francisco, another 500 in Seattle, 500 in Vancouver, 3,500 in Portland, Oregon, 99 on Latsch Island on the Mississippi River in Minnesota and 40 in Yellowknife Bay, NWT. flickr.com

Thames River near Hampton Court: Taggs Island, UK
Everyone on Taggs Island lives on a floating home; there are 40 hugging the perimeter and 20 in the central lagoon, all attached to piles driven into the riverbed. More info: taggs-island.com Pic Grahamsjz flickr.com
Every year the river homes become locked into the ice in the Latsch Island Boathouse Community on the Mississippi River. The extra weight of thick ice and snow needs to be removed from the roofs and decks of floating homes. The residents of this community also tie their homes to the trees during the spring swell.

Floating House With Solar Panels And Roof Garden
Equipped with an incinolet toilet which burns waste instead of creating more sewage. Drinking water is collected from rainstorms and filtered into a glass partition wall inside. The inner temperature of the boat is regulated by a geothermal pond loop which runs from the bottom of the water source through a piling supporting the dock and into the floor of the boat.

Environmental Impact Of Houseboats
An issue with houseboats is that most flotation systems aren’t yet green. Used most are log floats, solid styrofoam encased in rubber, foam filled steel pontoons, positive concrete, concrete pontoons, concrete and foam, wood and foam, polyethylene shell with solid core polystyrene block molded inside, fiberglass and envirofloat.
For waste, you must use incinerator toilets, compost toilets or a hook up to sewer services along the dock.
In Lozman v. City of Riviera Beach, Florida, U.S. Supreme Court, No. 11-626, a decision was rendered that floating structures be treated as land-based homes, not as a vessel subject to maritime laws.
We can now reimagine this scene.
