24×30 Cabin Plan

24x30 Timber Frame Cabin

This 24×30 timber frame cabin packs a ton of style and interest into its 956 square feet! Talk about curb appeal: the access porch is enhanced by a hammer-beam truss and extended purlins to create a dramatic sense of entry. If you enclose this space you end up with 1036 square feet. The top of the main structure’s tie beams are almost 11 feet high, making for a great ceiling height. The lean-to wing climbs from an 8’ eave up to 13’ at the apex of the principal rafter. The second level boasts 5’ tall knee walls and a roofline that climbs 9 feet beyond that, so the high-volume space continues. The center of the loft cantilevers out 3 feet, creating an interesting look-out over the main level space below.

This is a true two-level structure with lots of excitement and space to spread out. There are plenty of opportunities to add windows wherever you like. The queen post trusses on the gable ends will accommodate large apertures, and there is space for clerestory windows in the knee walls. The main level only has three posts on either end, so place your windows wherever you like!

When you purchase your plan, you will receive instantly downloadable pdfs. They are formatted to print at 11×17 for easy reading. The construction drawing set has 15 pages, and the piece drawing set has 64 pages of all the information you will need to complete this complex project successfully. There are 3D drawings assembled and exploded. Dimensioned plan, section, and elevation drawings examine every part of the frame. Detailed drawings show more information to explain the joinery. In the piece drawing set, there are exploded axonometric drawings, with each timber labeled and numbered. Those labels correspond to the extremely detailed and easy-to-read piece drawings for the timbers. We even include detailed timber, fastener, and peg lists. Everything you need to know is spelled out for you!

  1. The shed roof section of this design should have a strong top plate and rafters running from the top plate to the wall. The current design with beams running between 3 rafters will probably fail if there is a heavy snow load . Snow from the main roof will land on the lower shed roof, especially if a steel roof; the middle beam has to carry it all.

  2. Hi Mike,

    The Principal Rafter’s spanning length have been shortened by the braces underneath. That brace has another on the opposite face that is taking some of the deflection of the tie beam from the roof load above. Actually a neat arrangement. Yes the snow does fall off the upper roof. This 50% tributary area that the middle principal rafter carries of the roof (not all of it) has been alleviated by that member being a larger cross section than the End Principal Rafters.

  3. Please forgive what may seem a silly question to those who design & build these structures regularly. How is the cabin wall end of the hammer beam entry supported? The pictures suggest that the entire entry structure is balanced on the two vertical posts. Thanks!

  4. No silly questions. In that scenario, you would prop the beam ends on support built into the exterior wall that encloses the timber frame structure. Or if you didn’t want to penetrate any sheathing on the enclosure wall, pack the wall with studs at the area and fasten a corbel to the sheathed wall to hold up the beam. Good anchorage would be required.

  5. Thanks a bunch for the clarification. I can see where this provides for artistic creativity, if one is inclined. I appreciate that!

    Now, what’s up with this site requiring me to create an account to purchase these plans?

  6. Can you give the system another try, you should only have to create an account if you get the Plan Bundle. Let us know if you are still having problems.

  7. This plan has no floor. In fact, most – if not all – of the plans in the bundle have no floor! Let’s assume, for a moment, that whoever buys the plans doesn’t intend to build on a concrete slab – what do they do about a floor?

  8. Most folks do build their frames on top of a slab. We can draw floor systems on a custom basis. Check out our custom design services here.

  9. Hello

    Could you please tell me the dimensions of the main structure alone to the outside of the posts(those are 8×8?). I think I want to build it but with three bents, omit the lean to, and build the hammer beam section on the gable end as the vestibule.

    Thank you!

    The posts are actually 8×10. The main structure measures 18×24 to the outside of the posts.

  11. I really like your plans, especially the hammer beams. I guess overhangs are not authentic design elements but they are so beneficial that I would like to use them for my project.

  12. Jack – Some of our plans have overhangs and some do not. If the frame is designed to have walls such as this one we may omit them. It is not good to have interior timbers stick through the building envelop. To do that would in a heated/cool space would lead to moisture issues. There are ways to take our plans and modify them to add the overhang.

    I’m looking for a barn/ 2 car garage structure with a fill loft. The overall size of this design looks just about right. Will it accommodate 2 garage doors in the main strucutre and can the loft extend further that 1/2 way?

    The dimensions in the shed area are 12′-0″ outside to center of the posts, by 8′-0″ high from the subfloor to the top of the shed timber.
