The Standard Does Not Change With the Square Footage

The scale changes. The Mastrosimone Construction standard never does.

There is a common assumption that a builder known for large-scale work only takes on large-scale projects. It is easy to understand why. When people see aerial footage of a 29,000 square foot estate rising in Umatilla, currently the largest residential project under construction in Lake County, they assume that is the only kind of work Mastrosimone Construction pursues.

That assumption is wrong.

Mastrosimone Construction currently has projects at multiple stages of construction across Lake and Sumter Counties. One is an estate under 6,000 square feet that is nearing completion. Another is a home in the mid-3,000 square foot range in Mount Dora, currently at the foundation phase. The Umatilla estate is the largest. But none of them received more or less of Phil Mastrosimone's attention based on their footprint.

That is not how this company works.

What Mastrosimone Construction Actually Builds

Mastrosimone Construction builds fully custom homes for individual families. Not subdivisions. Not developments. One family, one home, one complete focus.

The projects range from $1 million to over $8 million. The square footage varies. What does not vary is the level of thought, craft, and detail that goes into every decision.

Phil, his son Ryan and their team would take on an 800 square foot project if the work called for the same quality, the same craftsmanship, and the same depth of planning that defines everything the company produces. A smaller footprint does not mean a smaller standard. It means every decision carries more weight. Every detail is more visible. There is nowhere to hide a shortcut in a well-built small home, which is precisely why building them at a high level is its own discipline.

The depth of thought that goes into an 800 square foot cabin is the same depth of thought that goes into a 29,000 square foot estate. That is what distinguishes a builder from a production company.

Why Alignment Matters More Than Square Footage

Because Mastrosimone Construction takes on a limited number of projects at any one time, the fit between client and builder matters more than scale.

The right client is not defined by the size of their budget or the square footage on their plans. The right client is someone who values craftsmanship, who wants something built the way it should be built, and who understands that a custom home of any size is a relationship, not a transaction.

That alignment is the foundation of every project Phil takes on. It is also why Mastrosimone Construction's retainer-based model exists. It is not about exclusivity for its own sake. It is about protecting the quality of every project by ensuring that each one gets the attention it deserves.

A builder who takes on more than he can give full focus to is not doing his clients any favors, regardless of the size of the job.

Three Projects. Three Scales. One Standard.

At this moment, Mastrosimone Construction has active projects at different phases and different scales in Lake County:

Umatilla, Lake County - The largest residential project currently under construction in Lake County. A multi-phase estate build that has required complex planning, structural engineering, and coordination across trades at a scale rarely seen in residential construction in Central Florida.

Leesburg, Lake County - under 6,000 square feet - A custom home in the final phases of construction. The same in-house woodwork, the same attention to material selection, the same standard of finish that the company is known for.

Mount Dora - mid-3,000 square feet - A custom home currently at the foundation phase. Mount Dora is one of the most distinctive communities in Lake County, and the home is being built to complement both the setting and the family's vision.

Three different projects. Three different scales. The scale changes. The standard never does.

The Craft Does Not Scale Down

In-house woodwork and metalwork are not features that Mastrosimone Construction reserves for the largest projects. They are part of how the company builds. Period.

When you commission a custom home with Mastrosimone, the built-ins, the cabinetry, the metalwork, and the millwork are made by the same hands regardless of whether the home is 2,000 square feet or 20,000. The capacity to produce that work in-house is what gives the company control over quality at every scale. That control cannot be purchased by the square foot. It is either the way a builder operates or it is not.

Four generations of building have produced a team that approaches every project, at every size, with the same principle: if it is worth building, it is worth building right. The scale changes. The standard never does.

A Note for Buyers Relocating to Lake and Sumter Counties

Many of the families Mastrosimone Construction builds for are relocating from larger markets, often from the northeast or from major metropolitan areas, where they have seen what exceptional construction looks like. They arrive in Central Florida with a clear standard in mind and they are looking for a builder who can meet it.

That search often leads to disappointment before it leads to Mastrosimone. The Central Florida custom home market is not short on builders. It is short on builders who operate at a specific level of craft and accountability, regardless of project size.

If you are planning a custom home in Lake County, Sumter County, or the surrounding area, and you want to understand whether Mastrosimone Construction is the right fit for your project, the conversation starts with the work, not with the square footage.

Frequently Asked Questions

Does Mastrosimone Construction only build large luxury estates?

No. Mastrosimone Construction builds custom homes across a range of sizes and budgets. Projects range from $1 million to over $8 million. The company takes on a limited number of projects at any one time, and the selection is based on alignment with the builder's standards, not on the size of the home.

What is the minimum project size Mastrosimone Construction will consider?

There is no fixed minimum square footage. The consideration is whether the project calls for the level of craftsmanship and custom work that defines how Mastrosimone builds. An 800 square foot project built with intention and quality is a better fit than a 5,000 square foot project that does not require or value that standard.

Where does Mastrosimone Construction build?

Mastrosimone Construction primarily builds in Lake and Sumter Counties in Central Florida. Current active projects include locations in Umatilla and Mount Dora.

What makes a custom home builder different from a production builder?

A production builder builds homes designed for efficiency and volume. A custom builder, particularly one like Mastrosimone, builds one home at a time, for one family, with every detail informed by that family's specific vision. The difference is not just in design. It is in the depth of involvement at every phase of construction.

Is Mastrosimone Construction accepting new projects?

The company operates on a retainer-based model and accepts a limited number of projects each year. Prospective clients are encouraged to reach out early to discuss fit and timeline.
