Roof is up!

Roof is up and sealed! Time to finish sheathing the sides and find some windows…

  1. Hi Denham,
    Really coming along well – keep going hard!
    1. I am concerned about the pony wall you have built to support loft rafters. basically you have created two short balustrades to stage the rafters in this area. As glulam slumps over time, it will force that partial wall outwards on both sides. Easy to address now (hard later). make sure rafters have Simpson ties at BOTH ends in loft area, also would be good to install steel strapping up the inside of the studs from say 24 below head plate, run them past the plate at least 12 inches above plate. do this in two or three locations on both side walls. Alternatively you could use long straps (48″) on outside of plywood sheathing once you have the roof plywood in place.

    2. Your enemy on the project is lateral stress forward and back, and side-to-side during transport. Best way to address this is to screw ALL you sheathing into the studs, don’t just nail it. AND you must make sure the plywood is very well fastened and glued to your sill plates – its from your sill plates that your structure will be able to resist lateral stress, so make sure your screw every 6″.
    3. You have to address air barrier and insulation in sill area above wheels. Build a box on the inside, then spray foam the heck out of this area. Make sure you provide a fastening surface at floor in that area, or when you go to install baseboard or cabinets you will perforate your air barrier when you fasten
    4. I think you need cross bracing at and below gable ends of your structure. It is narrow and tall, which can result in a ton of lateral force in these areas. Either Simpson strong-tie the wall diagonally from bottom to top from the outside, or let in a diagonal c=cross brace to your studs from the inside – don’t neglect this as you have very few interior partitions to help with sheer resistance.
    5. I am curious to know your intentions on roof insulation: are you building a cold roof, or a warm roof? Will be important in detail for rafter ventilation. membrane is ideal waterproofing but if you insulation 2X6 from underside you are creating a cold roof which is okay, but must have VERY good ventilation at soffit ends to discourage condensation and Mold growth.
    6. I don’t see a stud wall at gable ends on dormers yet? is this coming? you need to achieve R-28 in this area.
    7. I assume you will be creating a removable deck off the side on which your slider or French door reside? if so, pay attention now to welded embeds you will need to act as beam pockets for deck. You may run into a rot issue at your sill plate if the welded sockets create a deck flush to sill-plate level. code on residential housing says deck must be 4″ below door threshold – you might want to scratch your head about deck construction now to ensure waterproof barrier exists between sheathing and deck surface.
    8. Time to start planning you windows. This will cost you to buy the right ones but don’t cheap our with windows – most important area of house for pleasant living environment and also re-sale. If you are buying new you might try WESTEK windows Vinyl product line. remember windows do not add sheer factor, they take away from it. When you are ready call me, I can help you with window/wall config.

  2. This project will turn out fabulous, I’m sure. I wish there were some people in Quebec who buid these houses. It is so interesting to me. I am 63 years old and plan on building something verrrrrrrrrrrrrrrrrrry small next summer. The problem with tiny houses like this is that in Canada we have long winter, so living outside is kind of limited. It is my only concern. But what a great idea you have in using this huge trailer…. Good luck. I’ll keep watching through your blog.

  3. Can’t wait to see the next steps! What a great idea using the carnival trailer. I have arthritis and can’t climb the steps to a loft bed. This trailer is perfect, I wouldn’t even have to use a murphy bed!
    In the US you have to have a commercial drivers license to drive something like that, do you? It would be easy for me. I drove a big rig for a couple of years and won’t let my Class A/Commercial license lapse.
    I would be a snowbird if I were you. Unless you want to stay inside Canada. Western Canada is beautiful. I got to spend some time in the Vancouver area, just amazing!
    I’ll have this page on my desktop so I can check in!! Good Luck!

  4. Love the idea of using a bigger trailer frame, hope to follow how it all works out. I’ve done lots of stick house building and finishing in my life time,mostly houses on foundations but love idea of the whole Tiny house movement. Thinking small for retirement years.
