====== Planning Shomera ======

The idea of a DIY [[wp>Shomera]] was born from Pinterest inspired images and plans published to build it myself. It did not originate from a single plane, but rather from a collection of ideas I stumbled upon while browsing Pinterest. (Yes I am ashamed! m() 

|{{projects:diy_projects:shomera:fullsizerender1.jpg?nolink&153|Completed sample project from OSB}}|{{projects:diy_projects:shomera:fullsizerender5.jpg?nolink&220|The foundations and floor prep}}||{{projects:diy_projects:shomera:fullsizerender2.jpg?nolink&155|Two side panels fitted}}|{{projects:diy_projects:shomera:fullsizerender3.jpg?120|A foundation sample}}|{{projects:diy_projects:shomera:fullsizerender8.jpg?nolink&140|preperations for plastering}}|{{projects:diy_projects:shomera:fullsizerender4.jpg?120|roof structure types}}|

So the basic ideas that came from the online research and the core ideas are:

  - You can build with and seal [[wp>Oriented_strand_board|OSB]] as long as the right grades(OSB3) are selected.
  - It can be plastered with cement with the right preparation.
  - The base needs to be secured on concrete pillars for stability and seasonal movement.
  - Proper insulation using [[wp>Polyurethane|Polyurethane]] foam.
  - The right [[#Tools|tools]] for the job.

**Note:** In hindsight I discovered that this price excludes shipping and VAT and cannot ship to Ireland, so had to find another local supplier that can ship to Dublin.


===== Calculations =====



My hand {{ diy_projects:shomera:shomera_plans.pdf |calculation references and notes}} taken during "research" and design.

==== Roof Angle ====

The objective is to maintain a roof angle of more than 20 degrees for the roof tiles and weather proofing criteria.

The rafter design has a 2ft middle beam across the side areas of 8ft or 10th width. The final design will be 10ft wide.
