Self-Engineering a House: Exploring Unusual Designs and Innovative Materials

Constructing a house can be a straightforward process, following the plans provided by a builder or architect. However, there are times when you may want to push the boundaries of traditional residential construction. This article delves into the world of self-engineering a house, exploring designs and materials that go beyond the norm.

Understanding Traditional House Construction

Typically, the construction of a house is simple if you adhere to the provided plans. Engineering might come into play to address specific issues such as clearances between heating, air conditioning ductwork, electrical lines, and plumbing lines. Beyond this, houses are generally straightforward in design. If you are interested in unique designs and unconventional materials, consider searching Architectural Digest for inspiration.

The Role of Building Codes and Architectural Statements

In the USA, houses rarely require engineering due to conservative building codes. However, if you want to make an architectural statement, this might necessitate some engineering. An example of such a statement is the Robie House by Frank Lloyd Wright, which features a cantilevered roof made of expensively engineered steel.

Construction Beyond Standard Codes

If you wish to build a house without adhering to code requirements, you can explore alternative options. For instance, floors need not be as robust as those mandated by codes. Two by four (2X4) lumber can support significant weight but might result in a springy floor. To address this, you can use inexpensive solutions, though they may not meet code standards.

Another example is the concrete foundation. Building codes require a robust concrete foundation around the entire perimeter of the structure to prevent differential settling. However, you can build a house on pier footings just fine and simply monitor them over time. If any changes occur, you can adjust and reinforce the structure.

Classic and Contemporary Books on Self-Engineering

Rex Roberts’ book “Your Engineered House,” a classic 50-year-old reference, and Ken Kern’s “The Owner-Built Home” are excellent sources for rethinking traditional building conventions. Both books provide valuable insights and practical advice for those considering a self-engineered house.

I have applied these principles to all 50 houses I built. It is surprisingly easy. You simply follow the basic rules of window header sizes, and the truss manufacturer has already done the engineering work for roof trusses. For sheds, if the center of a roof truss can support your body weight, that is sufficient engineering. I always added extra plywood with screws in the middle of the rafters for additional support. The same principle applies to floor joists on houses. If you draft your house as an owner builder, the building department will often check for some engineering and suggest necessary changes.

Conclusion

Self-engineering a house is not as daunting as it may initially seem. By understanding the basics of construction and exploring innovative designs and materials, you can create a unique and functional home. Utilizing resources like Architectural Digest, classic books on construction, and applying practical engineering principles can help you successfully embark on this project.
