A beautiful fall day to be outside

Lots of things are percolating at the moment.  I am nailing down (so to speak) the final position for the entry door and all side windows, and getting set to order the patina green standing seam metal roofing and trim we will need.  I have also been researching a cement-polymer-coated rigid foam tile backing board, which I hope to use in the bathroom area -- 100% waterproof and very light. Here is what it looks like:

An artist friend of mine discovered how easy this material is to tile on (when she facilitated an awesome outdoor mosaic project), and how waterproof it is.  I plan to use the panels for the walls of the bathroom area, and probably purchase their shower pan too.  The molded shape pieces are a bit pricey but I can use this lightweight material now as is, and tile it later at my leisure.  If my tiny house alights more or less permanently anywhere I can tile it with ceramic or stone tiles.

Here is Shelby today by the trailer -- my tiny house "foundation" -- and a picture of the lumber which will be used to build the shell of the house. Thank you Barry! To me the trailer is looking a bit less like a utility trailer.  The skirting is bolted on with stainless steel bolts, lock washers and nuts, and Kyle has silicone-caulked each bay and everywhere that needed to be sealed from moisture.  At this point we want to be sure that not a drop of water enters from below, and I think the foundation has been sealed quite thoroughly. 

This photo shows caulking down in the bay where polyiso rigid foam and spray foam will be placed, as well as in the seam between the 2x6" borate-treated skirting (or fascia) boards and the frame of the trailer.  Note the channel made to allow for the threaded rod -- one of eight or ten I think -- which will secure the wooden wall framing to the "foundation". These rods are carefully welded to the outside of the heavy steel trailer frame.

Note the two rubber grommets in the frame and flashing. You might not realize that they are two different sizes (widths and depths) and actually I believe there are four (4!) different types of rubber grommets now protecting previously sharp-edged holes in the steel.  Wiring of different sizes for the trailer lights must pass through parts of both the thick steel framing and the thinner flashing in the floor of the trailer, and we felt that it was asking for trouble to let any wiring get jostled around or rubbed while the house will be underway.  I feel that the trailer is very well-made, and will be a quite satisfactory "foundation" for my tiny house, but kudos to Kyle for being thoughtful, thorough and ingenious about details like this.  My engineer father would certainly have appreciated (as I do!) the doggedness needed to protect each type of hole with its own appropriate grommet. A lot of time is being spent (on both of our parts) in looking ahead, and problem-solving small but important design and construction issues.  Which is VERY satisfying.
