Pacific Northwest Construction, LLC, of Molalla, Oregon specializes in the design and construction of pole barns and pole buildings, also called post frame buildings. Post frame buildings are composed of primary structural frames typically made up of a clear span truss supported by two columns and supported or connected by purlins (horizontal structures supporting the roof), girts (horizontal structures supporting the walls), and sheathing. Loads are transferred to the ground through columns, either poles or squared-off posts of pressure treated timber, typically embedded in the ground.

Why Are Pole Buildings So Affordable?

The Pole Framing technique of pole barn construction uses fewer larger framing members to span greater distances which cuts down on construction time and material cost. The poles or posts provide a strong vertical anchor and support for attaching the shell of the building. They replace the studs used in conventional frame building. The siding material is attached to girts which are bolted to the posts and running horizontally like bands at different heights. The roof is attached to the top girts of the longer walls usually using a truss system which can span longer distances and requires no interior posts and beams.

This alternative allows customers an opportunity to economically construct their dream building and in most cases, allowing them to have a larger building then they thought they could afford.

Pole barns and pole buildings are safe, reliable, and time-tested. Pole barn construction is an economical alternative to conventional building construction: generally only a small crew is required to set up the the poles, girts, and rafters. The finishing work requires far less labor, and can often be done by an individual. Post frame buildings are cost effective, require less maintenance than conventional buildings, and will last longer as well.

Pole Building Applications – Large Selection of Pole Barn Plans

Pacific Northwest Construction, LLC can work with you to design a custom pole building or offer a choice of many preexisting pole barn plans or designs. Applications generally include low-rise structures up to roughly a 50-foot sidewall and fall into the categories of agricultural, residential, or commercial buildings. Be sure to check out our Building Portfolios.

  • Agricultural Applications include animal barns, loafing sheds, riding arenas, stall barns, storage for hay or other products or equipment, nurseries, standalone roofs to shelter animals or other items from the weather.
  • Residential Applications. Pole buildings offer the best value per square foot of any residential framing method and can make any application you imagine a reality. They are an excellent choice for garages, carports, RV or boat covers, storage sheds or workshops. You can even build an entire home.
  • Commercial Applications are endless and seen everywhere. These include self-storage units, stores or retail buildings, warehouses, manufacturing facilities, even churches or strip malls. Pole buildings are a great way to save on costs without giving up the style or quality of your commercial project.


Pole Building Materials

With the advent of modern building materials such as metal roof and siding products in many stylish varieties and colors, as well as squared off pressure treated timbers replacing poles, pole buildings can be used for virtually any application.

Pole Barn Styles

While there are an endless number of possible designs, pole building styles are often characterized by the type of roof being used:

Gable Roof. The most common and widely used roof style, an inverted “V”, features a basic truss that is easy to construct and very affordable. Used in all applications such as homes, garages, barns, shops, and more.

Monitor Roof. Similar to a gable roof but with a raised apex along the entire width of the roof. The tall center section can allow for the storage of very tall objects or even for a loft in a residence, or a hay loft in a horse barn. The style is very popular for horse barns.

Gambrel Roof. This tall roof is what most people associate with an old fashioned barn. It is less common and somewhat more expensive than other styles. Sometimes it is used to add character to a pole building. Often an old fashioned cupola will be placed at the peak.

Single Slope or Lean-to. A very simple roof often associated with a shed or an animal shelter.

Hipped Roof. A variation of a gable roof often seen on residential homes or garages. Four triangular sides meet at a single apex point in the center.

Custom Designs. We can combine styles or develop any custom design to make your ideal building a reality. Check out our pole building portfolios.
