40×42 Monitor Barn House

Monitor Barn House
  • Description


Typical of all monitor barn plans, this 40x42 monitor barn house plan has a large center aisle with shed wings on both sides, and a second level above the center aisle.  If you are wanting a large structure with great character and functionality, look no further than this one!  This is designed to fit on a 40x42 foundation after the addition of 5 1/2" Studs, and 5/8" furring strips behind the posts for drywall to be installed.  You may choose to leave one of the wings open for a comfortable porch or enclose the entire structure. There is plenty of mortise & tenon, spline and scarf joinery for you to show off your skills!

The raw dimensions from outside to outside of the posts are 38’-11 ¾” x 40’-11 ¾”. With cladding, the square footage is approximately 1680 for the first floor and 650 on the second level. The roof pitches are  8:12 for the  center aisle, and 4:12 on the shed wings. The height to top of the center aisle rafters is  24’-10”. The  height to the top of shed rafters is 13’-3”.  The top of the center aisle rafters stand at 19’-7”, and the height to top of shed plate is 9’-6”. This plan utilizes 9009.3 board feet.

  1. Yes, they can. Check out our page, HERE, describing what we offer and the process of our custom design services.

    Fill out the design questionnaire so we can understand your needs. That’s the best way to communicate with our team and get an estimate for design services.

  2. Yes, we can modify the plans so they can be precisely what you are looking for or you can do it yourself. If you are looking for the whole timber package, we can also provide that.

    Have you ever put a frame like this on a pier foundation? I imagine there would just be a framed floor on piers that line up with the verticle Timbers.

  4. What would be in the house kit that would not be in the barn Kit of the same size? SIPs? I would be interested to know how the price would change for same kit for just a 40×42 monitor barn. Many thanks.

    The house kit could include your enclosure systems where the barn kit might not. Please go to our Kits page to find out more- we have an easy calculator on that page to figure pricing as well.
