Stand alone designs

  1. 1. Co-Created by Josh Gomez & Rosie Stonehill
  2. 2. Stand alone DesignsThis is a set of designs which came about from suchquestions as “How would I manage my gray water andtoilet waste?” and “how would I build a low impacthouse?”They are in not intended for a specific site, they aresimply a demonstration of the best possible designconclusions I could come up with if everything wereperfect, like I had a south facing hill side and no moneyrestrictions etcI know that it is likely that these designs would not fitexactly into our land when we have it but I felt it was agood design exercise to see how, ideally, I wouldresolve these questions.
  3. 3. Stand alone Designs Water conserving waste management designThis design is for a south facing hill side and incorporates a dry compost toilet with abath / shower room with the option of solar (for summer) or rocket stove (for winter)hot water and a washing house. All liquid waste (urine and grey water) drains to areed bed which then filters through to an open ring of trees encircling a mandalakeyhole raised bed and then the remaining ground water drains though the groundinto an aquaculture pond which acts as a reflective solar catchment, creating a superwarm micro climate for the trees and veggies on the raised beds.

  5. 5. Stand alone DesignsWater conserving wastemanagement design•Bathroom with year round hot water:Sunk in deep bath / shower space withroom for two, seats at either endwhich also function as steps to get inand out, and a plug hole in the centre.Summer (solar) and winter (rocketstove) water heating both storing hotwater in the same insulated water tankinside the bathroom situated abovethe bath, doubling up as room heatingand towel / clothes drying rack. Allgrey water from bath / shower andsink is piped to the reed bed system.
  6. 6. Stand alone DesignsWater conserving wastemanagement design•Scrub tank wash room: This, as of yet,has no fancy design as we have stillnot yet found the ideal ecologicallysound, quick and easy clothes washingtechnology. We have heard a lotabout pedal powered washingmachines though not personally seenone in practise but, to us, the obviousone, if there is a river on site, is tosomehow harness the energy of wateralong with it’s cleaning power to washour clothes. We are still working onthis! Whichever method used, the hotwater comes from the same source asthe bathroom and the water whichdrains from here, likewise, mixes withall other waste water and is cleansedthrough the reed bed system.

Allthe way through the reed bed thereare many baffles taking the waterabove, below, above, below to slow upthe flow and allow time for thecleaning process by the microbial lifeon the plants roots. At the end of thereed bed there is a small water levelkeeping tank with a man hole cover.
  8. 8. Stand alone DesignsWater conserving wastemanagement design•Ring of fruit producing trees encirclinga keyhole mandala raised bed: Afterthe water has come out of the treebed, it is channelled in gravel filledtrenches firstly to the fruit and nuttrees. Any excess to what they requirefunnels into the centre of the raisedbed through the gravel paths and isabsorbed into the beds.
  9. 9. Stand alone DesignsWater conserving wastemanagement design•Waney edged aquaculture pond withvarying depths, increasing solar gainand habitat diversity: All overflow fromthe raised beds and surrounding landcollects in the pond. This has a smallfish stock consuming the lastremaining nutrient content from thesystem and fertilising the water whichcan then overflow to irrigate othersurrounding crops. The pond,mandala raised beds and tree circleare orientated in such a way that itcreates a very beneficial microclimateto support life turning waste waterinto an abundant variety of valuableproduce.

  11. 11. Stand alone Designs Low the principles of passive solar heating and coolingThis house mainly demonstrates impact houseusing as natural materials as possible, wherever possible.There is a lot more to the low impact house that, as of yet, I have not gone into. Itseemed more important to me to get, first of all, the right arrangement ofharmoniously compatible and cooperating elements to form the initial structure. Oncethis arrangement is found, it is easy enough to have a warm house in winter and a coolhouse in the summer. This is the basis of comfortable living. Other low impactattachments can easily be added on, for example, solar panels, an efficient, multifunctional wood burning stove etc.

Stand alone Designs Low impact house•In this design there are 3 main elements:greenhouse/kitchen, central octagonal livingspace/bedroom and shadehouse/verandawhich are joined in such a way that there is noreal border between them. They graduallyblend into one another forming one singlestructure which is both very functional andcomfortable whatever the weather outside.• Shade side Shadehouse/veranda: this spacebecomes most comfortable in the summerwhen it is just the right place to spend themidday hours relaxing .
