How much does it cost?
Strawbale homes are labour rigorous, and when being built by paid labour this will enhance the cost. Strawbales are relatively cheap so people equate this to a complete house being cheap, however wall surfaces may only be 14-20% of the expense of a building. The expense of the wall space includes construction level bales (which might be up to $9 each), the price tag on materials to use compression to the bale wall surfaces, and the expense of rendering 3 jackets. A deal built house can cost from $1750 rectangular metre upwards depending on level of end and the house design.
The higher level of insulation that strawbale building provides is not easily or cheaply replicated in other building methods. To insulate other varieties of development to the same level (R8) as strawbale could make them more costly than strawbale structure. Strawbale homes offer permanent cost savings due to advanced of insulation they offer, reducing cooling and heating costs.
I believe an extremely energetic, resourceful practical owner contractor could create a house for about $800 per square metre, however almost all of us are not as resourceful and energetic as we would hope to be, and could create a house from around $1300 per square metre.
Generally I realize that owner contractors undertake the obstacle of fabricating a tactile palm built home, whether using used building materials or new, even though the completed home is a superb credit with their skill and potential it may well not have been a cheap house. It really is probably a nicer house than they may have afforded to get contractor built. They could experience their praise when they sell their house.
What about drinking water?
Moisture is the largest risk to strawbale structure. Damp bales shall decompose which will certainly reduce their durability, decrease the known degree of insulation, may create bad levels of bacterias, and create costly and inconvenient maintenance. Focus on information and creating a homely home with well-designed normal water obstacles is vital.
Bath and showering areas- I really do not advocate that bathtub areas or baths be installed next to strawbale wall surfaces without additional ways of moisture control. Laundries and kitchen areas sometimes overflow internally therefore i also recommend inserting strawbale walls over a plinth or up stand (to keep them above floor level by 50 -100mm), this plinth shall reduce wicking of water up in to the bales.
Good Design- strawbale structures will include aspects such as appropriate eaves and verandahs. Landscaping design can even be made to divert rainwater and surprise drinking water away form the dwelling (i.e. bushes planted to divert travelling rains from straight hitting surfaces).
