1<strong>Platform</strong> ConstructionBeing what we call a ‘soft’ structure, the yurt reacts more readily to climatic conditions than do ‘rigid’structures, therefore it is important to choose your site carefully and take into account prevailing windpatterns, overhead tree limbs, water runoff, etc. In general, the best site would be protected from thewind, would receive morning sun and afternoon shade and be free from overhead objects such as largedead tree limbs that could damage the yurt in heavy winds. <strong>Plan</strong> your entry so that the doorway facesaway from prevailing winds.For a secure and comfortable installation, a well-built platform is necessary. To ensure a weatherproof installation the platform needs to be circular and the same diameter as the yurt so the side coverfabric can extend below the interior floor level. This will provide a draft-free and watertight seal.Any exterior decking should be separated from, or at a lower level than the yurt platform. Unless youare skilled, enlist the help of an experienced carpenter for building the platform.The following plans show the typical construction of the yurt platform. Keep in mind that every sitewill be different, so the platform construction and footings should reflect the conditions of eachindividual site.Notes:1.) The bottom portion of the drip edge willbe visible once the yurt is installed. Itshould be stained or painted to match theexterior color scheme.2.) The 1" portion of the drip edge thatextends above floor level will be visibleon the inside and can be painted orstained to match the interior colorscheme.3.) Plywood skirting (to prevent airflowbeneath the floor) and a vapor barriermay also be desirable.4.) If you plan to connect the yurt to anexisting building (or another yurt) besure to allow a minimum of 12" betweenthe existing building and your yurtplatform. A covered walkway can bebuilt to connect the two after the yurt isinstalled.5.) Keep in mind that the windows open fromthe outside. If you plan to have theplatform elevated you should consideradding a catwalk or exterior decking forwindow access.6.) If you plan to install a “floating” floor onyour platform, please contact <strong>Pacific</strong><strong>Yurts</strong> for recommendations on how toprepare the platform.7.) When using the 2x6 T&G flooring be sureit is kiln dried and has a low moisture contentto avoid gaps as the wood dries.The original designer and manufacturer of the modern yurt, leading in quality and service for 30 years.77456 Hwy. 99 S. • Cottage Grove, OR 97424 • (541) 942-9435 • FAX (541) 942-0508 • E-mail: info@yurts.com
2<strong>Platform</strong> Construction Overview1.) Lay out pier blocks accordingto framing plan and level.Note:Poured concrete footings may be substitutedfor pre-cast pier blocks.2.) Cut 4x6 beams to length, level them,and fasten onto pier blocks.3.) Cut 2x6 perimeter blockingand fasten to 4x6 beams.4.) Install floor insulation (optional).Notes:Diagram assumes level site. On sloping terrainvertical support posts and cross bracing may be necessary.If 1 8" plywood flooring is used we recommend adding2x6 blocking between beams (four feet on center).If you plan to purchase the cable tie-down option an extra4x6 block will be needed in the center of the platform.5.) Fasten flooring (1 1 8" plywood or 2x6 T&G) onto 4x6beams.6.) Cut flooring into circle with diameter matching that of the yurt.7.) Staple 2" wide strips of tar paper onto edge of cut flooring (or usecaulking) to provide a seal between flooring and drip edge.8.) Cut 3 8 " exterior plywood (OSB is best for small yurts) intostrips of desired width (at least 8") and fasten aroundperimeter of flooring so that 1" protrudes above floor level.This is the plywood drip edge.77456 Hwy. 99 S. • Cottage Grove, OR 97424 • (541) 942-9435 • FAX (541) 942-0508 • E-mail: info@yurts.com
