If you're after a structure with real presence, one that pairs heritage barn character with everyday livability, the 40×42 Monitor Barn House delivers. The classic monitor profile features a soaring center aisle flanked by lower shed wings, topped by a raised second level ideal for vaulted ceilings or an oversized loft. Built on a 40′×42′ footprint, the timber frame can be fully enclosed for maximum living space or left partially open to create a generous wraparound porch.
As drawn, it's a 4-bedroom, 2.5-bath home totaling 2,330 square feet across two floors, but the frame is a blank canvas. Finish it as a forever home, a weekend retreat, a barndominium, or a working barn.
Floor Plan, Dimensions & Timber Frame Joinery
From post to post, the frame measures 38′-11¾″ × 40′-11¾″, yielding roughly 1,680 sq ft on the main floor and 650 sq ft upstairs. An 8:12 pitch crowns the center aisle at 24′-10″ to the peak, while the shed wings sit at a gentler 4:12 pitch and 13′-3″ height — the proportions that give a monitor barn its signature silhouette.
The frame is built from over 9,000 board feet of heavy timber, joined the traditional way: mortise-and-tenon, splines, and scarf joints throughout. It's an ideal design for anyone who wants their joinery on full display.

What's Included
We take immense pride in our team of exceptionally skilled timber frame designers. Each member is not only equipped with the finest tools but also possesses a profound understanding of how different materials intricately come together to realize your vision. This deep expertise in both design and material synergy is crucial in crafting the ideal timber frame structure tailored just for you.
Our commitment to excellence extends to our engineering team, specialists in timber frame structures, many of whom hold doctorates in their field. Sharing your passion for timber framing, our engineers work closely with you, ensuring that every aspect of the frame's design is customized to suit your specific location. This collaborative process guarantees that you receive all necessary documentation for permits, including detailed engineered reaction diagrams, ensuring your construction proceeds smoothly and stays on schedule.
The culmination of this meticulous process is a comprehensive set of construction drawings. These detailed plans not only provide a clear guide for your kit's assembly but also include a complete list of timbers and fasteners, serving as an invaluable reference throughout the installation of your frame. Our goal is to ensure that every step, from initial design to final construction, is seamless, transparent, and perfectly aligned with your project's needs.
After we've collaboratively chosen the ideal wood type for your project, we proceed to source the highest quality timber through our network of trusted mills. Ensuring that every piece meets our exacting standards, we then transport the timber to one of our cutting facilities. There, the joinery is meticulously crafted using CNC machines. Every joint, drilling, mortise, and tenon is cut with precision, adhering to tight tolerances for impeccable quality and fit.
Following the cutting process, all timbers are systematically labeled according to the production numbers assigned during the creation of your model and plans. This meticulous process ensures that every component of your timber frame is prepared with the utmost attention to detail, ready for the next phase of your project.
Included with your package are all the pegs, fasteners, screws, and connectors you need to put your ready-to-raise frame together. You will also get a detailed list for you to refer to while raising your frame.
We carefully package and securely transport your timber frame and all necessary hardware directly to your location. In sync with you, we'll coordinate the delivery schedule, ensuring that we agree on an approximate time on the designated date. To facilitate a smooth and safe unloading process, it's important to have equipment on hand capable of lifting up to 5,000 lbs. Once everything is delivered and in place, the exciting phase of bringing your project to life begins.
At Timber Frame HQ, we embrace the philosophy of 'One Person, One Project.' This approach ensures that each client is paired with a dedicated Project Manager who will be your point of contact throughout the entire project. We believe in offering personalized, consistent support to make your journey with us as smooth and fulfilling as possible.
Our commitment extends beyond just providing exceptional timber frames. As your construction resource, we'll be by your side for the duration of your project, ready to offer expert advice, support, and answers to all your queries. Our goal is to make the process of raising your timber frame not just successful, but also a deeply rewarding experience.

Can this be built so as to allow a generous eave to allow a full wrap with strawbales?
Yes, there are several ways to increase the overhangs to accomplish this. Please reach out to the design team to discuss.

Rodney, please visit our Kit page and click Get an Estimate for your answer!
Can the monitor barn house plans be reduced to 30′ W X 24′ L?

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.
Can this be made as a non-house option for use as a barn/garage
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.
That is correct. You can either have a timbered floor system or a conventional one.
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.
CAN DRAWINGS BE IN DWG FORMAT?
No, we do not provide .dwg files. Only PDFs
