Estonian firm Kodasema is developing a prefabricated concrete micro-home that can be assembled and installed on-site within just seven hours, then moved to another location with relative ease. Once it's ready for market, the home is expected to fetch roughly €100,000 (around US$111,000), excluding transport costs.
Koda is built from concrete and ships in prefabricated sections, so when it arrives on-site, it only takes roughly seven hours to assemble and put into place. The home uses just 9 cubic meters (317 cu ft) of concrete in all. No foundations are necessary and it can be placed on gravel, asphalt, and other surfaces, providing it has a level footing.
While it's certainly no towable tiny home, it is promised to be relatively easy to move around. If the occupant wishes to change location, dismantling and preparing the home for transport can take around seven hours and involves a crane and truck.
The home comprises a total floorspace of 30.3 sq m (326 sq ft), mostly taken up by a large living room and kitchen area on the ground floor. Also on the ground floor lies a bathroom with toilet and bath/shower, while stairs lead to a small bedroom area and laundry room.
Kodasema is keen to promote Koda's sustainability and efficiency. The windows are quadruple-glazed and, while it requires hookups for water, electricity and sewage, the home's roof-based solar-panels will reduce grid-based requirements.
Insulation performance sounds very good too, with walls rated at a U value of 0.1 W/m²K, and windows with a U value of 0.3 W/m²K. Put simply, this should mean that it's cheaper to heat and cool.
The firm also says that it is looking at producing models suitable for use as a classroom, cafe, office or workshop, for example, and offering furniture as an all-in one package. A company rep told us that Koda homes are expected to start selling them in quantity next year.

In the Us we use the R value to have a simple number to determine the resistance of heat transfer. If this only has an R of 3 then is is not very good.
Poland is a great source of AAC and that would be far better than just plain concrete, much lighter and far more heat and sound resistive.
Might be nice to have a soapstone floor on AAC.
Quadruple glazing seems to be overkill and out of balance.
Solar panels on the roof plus maybe a side might be ok if they ar as high efficiency as possible.
From an aesthetic perspective this is very nice, but the cost projection seems to be too much.
I'd be inclined to compact a bed of crushed limestone, 3/4" to 2" as a base. Maybe 12" thick. The voids will hold the temperature.
A series of these staggered would make for a fine townhouse complex... of course plumbing is an issue but with more units the price would go down.
All in all, a great design, the best yet. Bravo!
A Bill Allison Wind engine at 59% efficiency would be a great addition.

I hope it does not fall apart as quickly as it was built.
It definately looks good, i hope it works out for whoever is making it.
