It uses WikiHouse products WREN and SPARROW. It has been designed primarily for use in the UK, but could also be adapted for other countries and regions. The home can be largely self-assembled, and costs around £37,000 GBP to produce. Our files are also intended as starter files for architects, designers, engineers and others interested in getting to know the WikiHouse WREN system.

Buy locally 18mm plywood in the standard sheet size of 2440mm x 1220mm (8' x 4') All construction is dangerous. Always wear hard hards, eye protection, ear protection (malleting gets very loud), gloves, high visibility outfits and steel-capped boots. Where working at height is required, use a harness. Establish a ‘safety first’ culture on site, and encourage the continuous identification of hazards. * If you would like to know more about WikiHouse, visit [http://www.wikihouse.cc/ our website] * If you are interested in a partnership download our [http://www.wikihouse.cc/WikiHouse_Partners_2016_v1.7.1.pdf full brochure] none Download on our [https://github.com/wikihouseproject/Microhouse/ Github repo] the set of milling drawings which can be used by CNC cutter to fabricate the house parts. Cut the part by a CNC mill using locally bought material. This is 18mm plywood, in the standard sheet size of 2440mm x 1220mm (8' x 4') Each component can be combined or adapted to form a structure which responds to an individual site or set of needs. '''Site preparation''' Make sure passers-by can’t wander onto your site. It’s also a good idea to warn neighbours in advance that there’ll be some noise, especially from malleting. Almost any foundation type can be used, provided it can support the joist ‘rails’. The rails must be level and parallel (+/- 5mm). Consult a builder or engineer to assess design and specification of foundations. '''Floor area''' 37.5m2 '''1. Service location jig''' CNC manufactured to set precise location for service connections. '''2. Trench Foundations''' Depth of concrete will vary. '''3. Bolts''' Fixing into concrete, ready to receive brackets. '''4. DPM''' Trap two strips of damp proof membrane (DPM) beneath joist rail, with about 200mm sticking out to outer side '''5. End walls''' Concrete or brick wall with ventilation holes. Use timber (for example, the battens) to create a temporary assembly deck. The deck needs to be stable and not bounce when malleted. Set out the parts for each section onto the ground, assembly is like a jigsaw. Pledge together the two layers to form a single section. Fit skis to underside of each superbox frame before raising. Stand the sections up vertically, positioning them at 600mm intervals. Fit the connector pieces into the slots in the section. These should be staggered alternately. Use the mallet provided on the milling sheets to hammer these tightly into place. Fit the internal and external cladding panels onto the structure. Internally these usually need to be screwed into place. Use bolts and/or large screws, depending on the foundation type. Always consult an engineer or building professional, especially to ensure footings are adequate. During high winds, uplift can be very strong. '''Heavy duty brackets''' Onto rail joist '''Drainage''' Install underfloor soil pipe plus shower and washing machine drain before surrounding with insulation. You may wish to skip all but the two end bays for now. '''Layers''' Wherever rolled insulation is used, two layers will be required: 100mm + 150mm = 250mm '''Wrap''' Work upwards, giving at least 200mm overlap. Ensure all folds are double wrapped and ‘weathered’ so water will run downwards. '''Openings'''  Don’t cut openings until you are ready to fit windows, unless you need them for access. This way, the chassis is protected from rain during the build. Use airtight tape (Tescon or similar) '''1. Seals''' Around all service penetrations '''Vapour barrier''' Use a tough vapour barrier (eg Intello) that can be stapled directly. If using a thinner vapour barrier, all staples will need to be over-patched with tape. '''1. Flashing tape''' Around entire opening before fitting window '''Window unit''' Install as per manufacturer’s instructions. In most cases, front face should be flush with chassis. '''Expanding tape''' Fit to windows seconds before installing unit and allow to expand. Pinch corners slightly to ensure no corner gaps. Check complete seal around unit. If possible add additional flashing tape to exterior. It is impossible to be too thorough. Wind will drive rain into even the smallest crack. Apply black flashing tape to front of battens. This will be visible in the gaps between panels. TATA Colourcoat urban steel roofing. Install as per manufacturer’s instructions. '''Wet room membrane''' Applied over drywall and floorboards in bathroom. '''Drywall''' Plaster panels fitted using drywall screws, then taped and filled as per manufacturer’s instructions. '''Floor overboarding''' Screws may be used but not removed to avoid air leaks. '''No visible screws''' Parts B13, B14, B16 and B21 should be screwed from inside, so no screwheads are visible from outside. '''Mirror''' Sits behind B13 and B14 '''Cutting holes''' Use a drill or jigsaw to cut holes in the unit to fit around pipes where needed. '''Bumper push latch''' Fit by hand to all doors '''Packer''' Use cork packer between frame and opening where needed.
