How Panelized Homes Are Built: Step by Step from Design to Delivery

Show Notes:

Ever wondered what actually happens from the moment you call Landmark to the day your panelized home is standing on your foundation? This episode walks through the full panelized kit home process step by step: the first call where Steve clarifies your location, codes, budget, lifestyle, and home type; the purchase agreement with a guaranteed package price; and the behind‑the‑scenes design work where architectural plans, structural engineering, and energy calculations are all coordinated to create a buildable plan set, not just a pretty drawing. Steve explains how wall panels, floor systems, and roof trusses are precision‑built in a controlled factory environment, labeled, bundled, and delivered by semi to your site on a schedule that fits your crew and access constraints (even for tight historic streets, steep mountain roads, or islands). He then follows the on‑site sequence—from unloading with a forklift and assembling labeled panels per the detailed assembly drawings, to inspections, drying in, mechanicals, insulation, and finishes—showing how Landmark’s upfront “homework” dramatically reduces changes, confusion, waste, and delays compared to conventional stick‑building, while still giving owner‑builders a fully custom home.

Transcript:

Steve Tuma: And that’s what I call doing the homework up front. We’re designing it, making sure it’s right for the customer’s needs and sensibility of building it.

Interviewer: Hello everyone, and welcome to Episode 80 of the Panelized Prefab Kit Home Building Show.

With me as usual is the President and Founder of Landmark Home and Land Company, a company which has been helping people build their new homes where they want, exactly as they want, nationwide and around the globe since 1993, Mr. Steve Tuma.

Steve, how’s it going, buddy?

Steve Tuma: It’s a great day again. It’s always a good day to talk about panelized homes and how we can help people.

Interviewer: It’s always a great day. It’s always sunny and happy. When is there not a good day to talk about building homes?

Steve Tuma: Exactly. Today’s a better one though.

Interviewer: The past few episodes of the podcast we’ve talked a lot about concepts and the basics of panelized home building, and I thought we’d continue that today by having you dig deeper and take us step by step through the process of just how a panelized home is built and constructed.

And of course, no one on the planet is better qualified to take us on that journey than Steve Tuma.

Are you good with that?

Steve Tuma: Yeah. It’s a lot of detail, so we’ll probably give a quick overview, and then as customers call in or work with us on getting plans going and the whole process, we can get into the finer details. But yeah, definitely — this is one with a lot of information.

Interviewer: Excellent. So I thought we’d do this as a, like I said, journey‑type thing. Imagine that me — I’m a customer, and I’ve decided to work with Landmark. I give you guys a call and say, “Okay, let’s do this.” So walk us through this. What happens during that initial call?

Steve Tuma: Well, that initial call is pretty interesting because initially we’ll talk generalities of:

“Hey, where are you building?”
“What are you building?”
“What type of house? Do you have an idea?”
“When do you want to start?”
“Is there a budget range you’re trying to stay within?”
“Are there features of the home? What kind of home is it? Is it a weekend home, your second home, your third home? Is it your main home, retirement home?”

So those are the general ideas that we’ll discuss, to kind of fine‑tune the process and bring the details together so that we can get a grasp on what’s exactly going on with what the customer wants to do. And then we can sort out the best way to help them.

It’s also, “Where are they building?” Because if you go build a house in Iowa, the codes and details are generally different than if you do something in like Florida, or New York, or California, or Texas, or any of the other states.

So we like to get an understanding of what it is so we can fine‑tune how we can best support and help a customer develop their project and move the project along.

So that’s basically what we do. And then from there, we get into discussions on their timeline — when they want to start, what type of foundation, types of windows, types of roofing systems. Do they have different ideas for heating and cooling, and all those details.

At some point they’ll say, “Hey Steve, let’s start. Let’s do this.”

So we have a simple purchase agreement — kind of outlines the cost. Oh, by the way, we give a guaranteed cost for the house package. So that’s pretty cool. People can rely on that for:

The plans
The structural design
Energy calculations
Whatever details they need for the building department

Then we put the package together for them so they’ll have the plans to submit for permits. And after the permits are issued, we then put the home package into actual production.

So that’s it.

Now, as far as how this all starts — there’s the actual production of the panelized home package, and then there’s also the, “How do you actually build the house?”

So the actual construction of the panelized home package is done in our production facilities, where basically what we’re doing is creating a more efficient process of stick‑building. Okay, so it’s not a modular unit where two halves come out or four different pieces come out to make a unit. It’s more like an efficient stick‑building process.

So they’ll make the wall panels in a production facility so that every panel is pre‑made — so basically, when assembling a home package, they’re putting wall panel one up, wall panel two up, wall panel three, going around. Instead of conventional stick‑building where they’re getting the wood, cutting it, measuring it, putting all the details, making a wall there and then assembling it.

So it’s a better‑controlled atmosphere, building it off‑site. And what that allows us to do is also have the assembly on‑site considerably quicker. Some people say it’s half the time, maybe even a little bit quicker.

The roof system is built with roof trusses, like conventional stick‑built roof trusses, and then we supply the materials for any floor systems, the roof sheathing, sub‑fascia, bracing materials and other details. We’re basically supplying the complete wood structure of a home.

Again, the key to it is that it’s a more efficient method of stick‑building, so we can go through and do truly custom design. We’re not limited by the production facilities like in modulars, where they have to go down a production line and the units have to be rectangular within certain specifications.

We can go through and do a truly custom home. Whether it’s something of a more simple design — like the typical American ranch home — or something where someone wants to get into a late‑1800s Victorian, or you want to get into mid‑century modern homes, prairie‑style designs, very modern designs — we can work with all those designs to go through and completely architecturally and structurally design the home package so it’s easy to assemble on site.

This is the point that I’m not sure customers completely understand — the amount of work it takes to properly design a home for any stick‑building or our panelized system:

To make sure that beams are the right size
Make sure that beams fit in places
Make sure the ceiling heights are right
Make sure wall heights are right
Make sure shear‑wall engineering concerns are taken care of
Make sure load paths are right

A lot of people think there’s this magic button where plans just magically appear. No — we’re actually going through to make sure the house will go together. That allows for quicker assembly on site. Your stick framer is not out there deciding what a house will look like.

The reason I say that is people don’t always understand that not all plans are the same. So someone could have a set of plans that looks good, but the details aren’t there. We’ve actually had plans wh...
