Tutorial 82 - Medeek Wall API (18:43 min.)



I think with all the rapid developments in AI there will begin to be an increase in AI assisted workflows.  We are only seeing the beginning of this.  Honestly, If I don't develop this API I will simply get left behind.  I will need to add in many more methods (ie. draw_door, draw_window, draw_column etc...) I also need to do this for each plugin.

Version 3.7.8 - 03.24.2026
- Created the Medeek Truss API.
- Enabled the following methods within the Medeek Truss API: common_truss_draw, validate_medeektruss, truss_regen, common_truss_read_attributes, common_truss_get_attribute, common_truss_set_attribute
- Added the Medeek Truss API Documentation page to the website.
- Added the Medeek Truss API - Common Truss Attribute Library Index page to the website.

Nice!  Looking forward to the pics/story!

The permit has closed on this house, any further discussion on it will be at topic 20x30 One Story Southern AZ from now on.

The structure / exterior of this house was built with Countryplans 20x30 'The One Story Cottage' plans.  It was built by me and my family over the period of a couple years from raw unimproved land.

I waited until our permit closed to post photos.

Will post construction photos soon.

Oh it is :d and has been now for 15 years  

You'd typically use a birdsmouth at both ends of a shed-roof rafter so each end has a proper seat on the top plate. On the tall wall, it's still the same idea - the rafter gets a plumb cut for the wall line and a seat cut so it bears flat on the plate instead of just hanging off the face of the wall.

A couple things to watch:

• Don't overcut the rafter for the birdsmouth.
• Make sure you have enough bearing on both plates.
• Add the proper hurricane ties / metal connectors to tie the rafters down.
• Check your span, snow load, and local code before finalizing the cuts.

If the geometry gets awkward on the high side, some people use a ledger or dropped beam detail, but for a standard shed roof, two birdsmouth cuts is usually the normal approach.

I'd strongly recommend drawing one rafter full-size on plywood or on the floor first so you can test the fit before cutting the whole set.

A 16x36 cabin can work really well for what you're describing, and keeping it 16' wide is smart if you want to preserve the option of moving it later. If mobility is even a remote possibility, I'd be cautious about simple concrete pads/blocks alone for a structure that size. They can work for smaller sheds, but for a cabin you'll want something more stable and frost-resistant, like sonotube piers, helical piles, or an engineered pier system, depending on your soil and climate.

If you want to keep the lot buildable long-term, an elevated pier-style foundation makes a lot of sense and is much easier to remove than a full slab. I'd also think through access for a future move before final placement.

Your layout idea is very doable in 16x36. A main floor with one bedroom, bath, small kitchen, and open living area plus a loft for the second sleeping space would probably be the most efficient. Board and batten with a steel roof would fit the rustic look nicely, and an old cook stove could be a great feature as long as clearances, venting, and floor/wall protection are done properly.
Biggest advice: check setbacks, frost depth, and local code before committing to the foundation. That will drive the best answer more than anything else.

To help clear up the terminology confusion: the reason you're seeing different down payments is entirely about the bank's risk.

• Raw Land Loans (25-50% down): This is for land with absolutely nothing on it.. no roads, no power, no sewer. Banks view this as highly speculative, so they want a lot of your cash in the deal.
• Lot Loans (10-20% down): This is exactly what you are looking at. Because the lot is in a development and already has water, power, and road access, it is considered "build-ready" or an "improved lot." The bank feels much safer lending on this, hence the lower down payment.
  

As for lenders, absolutely skip the national banks like Chase or BofA.. they generally hate land loans. Your best bet is to Google "Credit Unions" or "Community Banks" in the specific Idaho county where the lot is located. Local portfolio lenders actually want to finance local growth and will have the 10-20% lot loan products you need. (Also, Rothbard is 100% right.. read those HOA covenants carefully before you buy to make sure they allow your specific build plans!).

One longer-term tip regarding "improved" lots: If you plan on eventually using this property as a rental or investment (like an Airbnb/STR), keep a detailed paper trail of what you pay for the lot and the utilities/infrastructure.

While raw land itself can't be depreciated on your taxes, all those "land improvements" - like the grading, utility hookups, driveway paving, and fencing - absolutely can be. You can use a tax strategy called cost segregation to significantly accelerate the depreciation on those improvements and save a ton on taxes. I've used SMF Cost Segregation Advisors for my projects.
 The nice thing about them is they will run a free preliminary benefit analysis for you upfront, so you can see exactly what your tax savings would be before you ever commit to doing a full study.

Good luck with the Idaho lot hunt! Stick to the local credit unions and you'll find the financing you need.
