For years, this home has existed on the plans. Studied, revised, studied again. This month, it became something you can see from the road. As a custom home builder in Umatilla, Florida, this is the stage of a project we look forward to most, when the plans finally start to take a shape you can stand in front of.
Raising the Frame in Umatilla

The truss deliveries have come one after another, load by load, until the shape of the house finally matched the plans that have guided every step of this build. Setting them has taken a crane tall enough to spot from far outside the property line, a quiet marker to anyone passing through Umatilla that something substantial is underway.

There is a particular satisfaction in watching a roofline take form. It is a giant puzzle, every truss engineered and designed in advance by our truss designer, then set piece by piece until the pieces read as a single structure. For the first time, neighbors and passersby are getting a sense of the scale of what has been building here in Lake County.

The team from RoMac Building Supply, Blake and Chryston, came out to see the work in progress firsthand, watching the trusses they helped supply take their place on the frame.

Windows From Wisconsin
The Kolbe windows for this home are complete and currently held at our vendor's warehouse, staged and waiting for their place once the roof cap goes on. Our team recently made the trip out to Wisconsin to see where these windows are built, walking the factory floor and learning the product firsthand, not just from a spec sheet. Every opening on this home was measured and specified long before the walls around it existed, which is part of what custom building actually means. Not a home built and then decorated. A home considered in full, long before the first truss was ever set.
Closing In the Shell
The outer shell is nearing completion. Once the cap goes on and the windows are set, the house stops being a frame and starts being a building, sealed against the weather, ready for the work that turns a structure into a home.
That is where the next chapter begins. The woodwork. The metalwork. The thousand small decisions that do not show up in a set of plans but define how a house actually feels to live in.
The scale changes. The standard never does.
