jovoto / Hybrid House / 'The $300 House' Challenge / $300 House

This has excellent potential for mass duplication. My first negative reaction was about privacy and security with the windows so low and large.

Thanks,

@billie, I am working on the community plan and will have it up by the end of the day.

@calvinnhobbs88, I was thinking that the shutters would latch or lock from the interior. Maybe the opening toward the court could be bigger and the ones facing the exterior could be smaller and or higher.

Keep up the good work, consider/indicate costs

I will work on the providing costs

Aesthetically, I think your proportions are spot on for a building this size. Additionally, I think having low walls is an excellent idea as they will be less dangerous than full height walls in the event of an earthquake. If you have issues keeping it under $300, you could probably eliminate the interior ceiling and replace the shutter with curtains.

Thanks. The interior ceiling could be eliminated if absolutely necessary. The reason its there is that the metal roof can get very hot, so this allows the me to fully vent the roof so that heat is not transfered to the living space.

DVS I dont think you will ever need to remove the interior ceiling. It is of huge value and it can be built of anything. Woven banana leaf or any type of free material.

This strikes me as fun, attractive, and community oriented. Nice shutters. Structurally sound. Realistic for the budget depending on where materials are bought. Realistic idea of what a community needs to enjoy life. The communal cooking and sitting area could be larger. The drainage to the planter should be limited; add drainage going away from the community to prevent overwatering.

Deleted Userowner

Thanks. Yea, more planned exterior spaces would be great. I agree about the water/planter issue. I think maybe the solution would be that the water would be collected in a barrel from the washing station, this barrel could have a hose or just fill up watering pots to water the planter. This would allow for an overflow valve on the barrel, and to control how much the planter is watered.

Maybe add a cistern. What shortages and sanitation are major issues.

Sorry, that should say "water shortages" and sanitation are major issues.

kiwikiwi

Have you thought on how to collect rainwater? As clean water may be difficult to find it could be wise to think how the rainwater coming down from the roofs might be collected so that it doesn't wet the central area completely, and at the same time the water could be used as drinking water / washing / watering crops.

Hi Kiwikiwi, yes I think collecting rainwater would be very important. One of the good things about the shed roof is that it makes rainwater collection easy. I will add in a central cistern and gutters to the plans. Thanks

This is a good design. I suggest adding split bamboo on some of the windows for privacy. Gaps between the bamboo allow light and breezes through.

Another option is to add a natural soil stabilizer such as PolyPavement or a competing brand in the soil mix.

Deleted Userowner

Thanks Owen, I will look into PolyPavement

Someone sent me an email and said they know how to make PolyPavement. I think it's made from fermented fruit. I don't have the recipe yet, but if they can figure it out then I'm sure the details could be tracked down. This would probably be the lowest cost soil stabilizer. This brand and similar brands such as Terrazyme have been widely tested. No cement or lime required. It's safe and nontoxic.

The low solid walls with lighter framed upper walls is a logical solution and aesthetically very nice.

bdj108

Nice Idea. Glad that you have thought of using it in several climates. What is the pricing for this? I would guess it would be closer to $700 as your materials are fairly expensive. Also how would this be secured? It looks like it might be an easy target for theives.

Deleted Userowner

bdj108

Thanks bdj108, I am working am a cost slide the total is under $300. The only expensive material is the roofing, but this is one of the main similarities between all of the projects. The house is very easy to secure all you have to do to latch the shutters on the inside, also given the cluster your neighbors become part of your security.

Lovely design and good presentation.. I would like to see cost list.

Deleted Userowner

Thanks

Mixing this layout with a few other ideas, like the COB, stamped earth or earth bag (or mine, the mini-cord) would help most of us.

It is a great way to provide a solid foundation and reduce costs! Feel free to use the Mini-cord bottom, I can get you any info you want for costs (or just look at it, and cut it in half, since you only need the bottom.) Best of luck!

Thanks pbjosh, I agree, I think this idea is well suited to use/mix with a lot of the other proposals. One of the great things about this challenge is seeing all of the other great ideas and how they can influence each other.

Pedro_Almonte

I like your concept. Try to check PLATANHOUSE roof. It probably improved confort and reduce you price. It is something which abund tropics.

Deleted Userowner

Pedro_Almonte

Thanks, That would definitely be a good option for tropical climate.

PStouter

This is a lovely proposal. With your revisions, it really seems complete. All that I could add is that you will have to provide a solid foundation. If the CEBs are not cement stabilized, you might want to use gravel bags for the plinth wall, or stabilized CEBs. If the base of the wall is protected, an earthen wall survives well. And in high seismic risk areas the CEBs would have to be confined between reinforced concrete posts, right? I don't think most people are adding the reinforcement needed for high seismic risk areas into their base price, but it's something to consider. For cool areas, the CEBs could also have a layer of straw-clay added to the inside.

Deleted Userowner

PStouter

Thanks! Yea I think the CEB's should be stabilized and in earthquake regions you would need reinforcing. I think diffident precautions would need to be taken in each region depending on the natural disasters that affect that area.

bocita

this proj + proj ground up would make a perfect proj. cheers! i'd swap wood for bamboo or simil.

Deleted Userowner

bocita

Thanks, I am encourage that people thinking about combining aspects of other designs with mine. I think this sharing of ideas is one of the best parts of this challenge. And depending upon location and availably I would swap wood for bamboo also.

Coen Reith

Hallo DVS

A good design. Easy, fast and cheap to build by the people with a CEB machine.

Did you allso think about the foundation? CEB is just compressed earth and is water resistance against light rain attacks, but the bricks can not stand in the water in case of a monsoon rain. The clay part keeps the brick together, but will fall apart with to much water .

My advice is to build the first 30 or 40 cm with natural stones and a cement/lime mixure. You can allso press the foundation stones with geopolymer or concrete .

The connection between the foundation and the CEB's is easy, when the brick have holes inside. In the first two layers after the 30 cm foundation you can put concrete in the holes to make a solid connection.

All together this is a very realistic design and I wish you succes.

cheers.

Coen Reith

Thanks for the advice Conradius. I like the geopolymer option, Owen had suggested I look into that also. Unfortunately I can't add slides any more but I will keep working and refining this Idea.

I like this design. Simple, yet very versatile.

I like the design. Could you really build it for $300 around the world? What if I gave you the chance to prove it?
