Building a Modular Home

bump out additions

Episode 93 of hpd architecture + interiors’ popular podcast, The Architecture Happy Hour, featured Karen’s experience designing a modular home. In the episode, Karen described what prompted her to design her own modular home, how she decided where to place the house, and the advantages of building a modular home. In the podcast, we left off with Karen not yet securing the funding from her lender or having broken ground. In this blog post, you’ll find an update on the progress of this project. 

Setting Up the Foundation

The foundation of the project was poured in April, including all of the subflooring, the basement, and the basement ceiling. On top of this, there is plywood. This is the final step required to receive the walls from the Montana-based modular house kit company.

Soon after that, the company loaded up a truck with all of the panels and scheduled a date with Karen to have it dropped off. An entire house of walls fit into one semi-truck with a giant tarp over it. Although the roof trusses come in a separate truck, the included panels had the materials for the dormers, gable, and windows.

To get the pieces to the foundation, a crane moved the pieces from the truck, parked near the foundation, into the corresponding place. Each panel has two brackets to receive a giant eyebolt. Karen’s husband actually had the job of removing and putting in the eye bolts. 

An Unexpected Snowstorm

Unfortunately, the weather worsened around noon and became very windy. What was a relatively easy job became much more challenging as the panels quickly shifted in the wind and were difficult to get into the right position. Once they secured the corners at 90 degrees, the structure became more stable.

Two days later, before the project was finished, a big snowstorm came through. This left snow deposited within the walls. One of the walls was pushed off of the foundation. Fortunately, a neighbor noticed what happened and called the contractor at 10 p.m. on the night of the storm so that he could better support the wall that had become flexible. 

The next morning, when the construction team used a crane to fix the wall, they found that there was only one area of surface damage from where the panel crashed into a stack of plywood. There was also a small area along the plate at the bottom of a wall that needed to be repaired.

If this had happened with a traditionally framed house, the entire house could have been destroyed. The panels for the modular home were designed in a way that they could withstand a two-day truck drive on the highway.

Adding a Roof

The roof trusses were scheduled for the week after the snowstorm. It took a couple of days to add the roof trusses over the entire house. By adding the trusses, it was easy to see the possibilities for adding attic space or a loft in the vaulted ceiling. Over the guest bathroom, there is a high point where you could add a library ladder.

The kit manufacturer’s responsibility ends with the roof trusses. A local contractor will put on the roof and add all the plumbing and electrical components needed. With help from the contractor, the owner can be actively involved in the process of framing the inside.

Benefits of Adding a Modular Home

Opting for a pre-fabricated or modular home is a popular way to add square footage in areas where there aren’t many opportunities to build from the ground up. A modular home can be a workshop, garage, office, or extra living space while expanding the usefulness of your current home.

Additionally, you don’t have to disrupt living in your current home in order to complete a major addition or remodel.
