24×36 Timber Frame Barn House Plan


SKU: 40966 Categories: , , Tags: ,

This 24×36 timber frame barn house plan has plenty of room to become a comfortable family home. There are 864 square feet on the first level and 637 square feet on the second floor for a total of just over 1500 square feet. The ceiling of about one-third of the first level is vaulted up through the second floor, which creates a spacious volume of space. The three-foot-high knee walls and 10/12 roof pitch make for comfortable bedroom spaces on the second floor.

  • Over 1,500 square feet total
  • Volume ceiling living area
  • Thoughtful stairwell placement
  • 8×8 posts
  • 10/12 roof pitch

The construction plan set consists of 12 pages showing how the frame is put together. We give you 3D axonometric drawings from several different angles, so you can picture the finished product. There is an exploded view of the frame showing how the parts relate to each other. Then there are fully dimensioned plan, section, and elevation drawings. The 38-page piece drawing set shows each cut on every timber, fully dimensioned and in 3D transparent drawings. We also provide you with fastener and peg lists, and a complete timber list. All that makes your budgeting and material procurement straightforward.

When you make your purchase, you will receive a link to download the plan pdfs. They are formatted to print on 11×17  paper. You can print them on letter-size paper for studying, but when it comes time to build the frame, we strongly recommend having the plans printed full size on 11×17.

Important Information:

Timber Frame HQ provides plans for construction purposes but does not oversee the construction. The plan purchaser is responsible for assuring the plan meets local codes and regulations. It is the responsibility of the plan purchaser to obtain any and all structural analysis, engineering, and specifications that may be required in the municipality in which it is to be built. The plan purchaser is to verify all lot conditions and measurements before construction. Purchaser is responsible for additional expenses incurred in order to meet local code and engineering requirements.

The customer understands that the following conditions in your specific area may require additional engineering:

  1. Wind / hurricane / tornado
  2. Seismic / earthquake
  3. Heavy snow
  4. Flood potential
  5. Soil instability
  6. Timber Frame Engineering

The customer understands that HVAC, Plumbing & Electrical will not be included in all plans.

When you purchase a set of plans, you are purchasing a limited copyright license for a design giving you the right to build that structure one time at your location. Your copyright license was granted when you paid the purchase fee. You do not have the right to build the design a second time unless you have a signed agreement with Timber Frame HQ. Please note that copyright law protects “derivative works” the same as it protects the original design. That means that making some changes doesn’t make it a new design. We do not allow modifications of our designs by others, without permission. Your copyright license does not allow another professional to represent our design work as their own.

Timber Frame HQ retains all common law, statutory, and other reserved rights, including the copyright. This applies even when you have participated in the development of the design to a significant degree.

Plan Modifications

We are happy to modify and update the drawings to your specifications. We can adjust the footprint, roof pitch, overhangs, and overall heights. These will eliminate your mistakes in modifying an existing plan to meet your needs.

A couple of notes and requests:

  • Even the slightest change to the drawings can impact the time it takes to modify them. Most of the 2d drawings, timber list, and fastener list will need to update. The stock plans take between 15 hours to 40+ hours or $1,375 to $3,400+. Your project will not cost the same as the original, so that you will see savings.
  • Our design services are $85 per hour. Engineering services are $200 per hour. We have a minimum charge of $500 for our design work.
  • Lengthening (parallel to the main ridge) is more affordable than changing the width or adjusting the roof pitch.
  • We have made it a requirement that you purchase this plan for us to modify it. You need to have a copy of the plans so you can make changes that you want to make and mark them for us to review. In the end, if you don’t go with any of our services, we will be happy to refund you 100%.
  • Once you have purchased the plans and have reviewed them, please fill out the form below. It will get you into our system, and one of our team members will get back to you with an estimate for our services. Please include any of the following changes to the form’s “Other Project Info” section.
    • Overall width and length that you are after from the outside of the posts.
    • New 2nd Floor Framing Height
    • New KneeWall Frame Height (from 2nd-floor framing height to top of the top plate?
    • New Overhang Dimensions both for the sides and ends?
    • Any adjustments to the Roof Slope?
