Custom and semi-custom new home construction in Jacksonville and Florida’s First Coast

New custom home construction with two-story double porch, M&M Homes, Jacksonville, Florida

Building a new home is one of the most significant investments you’ll make and the builder you choose determines how it looks when it’s done, how it holds up over time and how the process feels to live through.

Our principals bring a deep appreciation for the architectural character of Northeast Florida’s established neighborhoods and that perspective shapes every home we build. Whether it’s a fully custom design on your own lot or a semi-custom build from one of our proven home models, we manage your build with the care and oversight you can be confident in.

Frequently Asked Questions

No. We can work with you whether you already own land, are in the process of purchasing a lot or need help identifying a suitable parcel. We’re familiar with available land across Duval, St. Johns, Nassau and Clay counties and can advise on lot suitability, zoning considerations and how a specific parcel will affect your build.

Custom construction starts from scratch — your lot, your floor plan, your selections across every category. Semi-custom construction starts with one of our established home models and gives you a significant range of options to personalize it. Custom offers more flexibility, while semi-custom offers more certainty on timeline and budget early in the process. During our initial consultation, we’ll help you understand which approach fits your situation.

From breaking ground to final walkthrough, most custom home builds take nine to fourteen months depending on size, complexity and permitting timelines. Semi-custom builds on established plans typically move faster. We develop a realistic project schedule during pre-construction and communicate proactively if anything shifts.

Yes. Every custom home begins with a Design & Preconstruction phase that includes design development, preliminary budgeting, technical coordination, and construction planning to deliver more accurate pricing, fewer surprises, and a smoother building experience.

Every custom home starts with a discovery consultation: how you live, what you want the house to do, and the investment you have in mind. From there we move through lot analysis and space planning, then into in-house design development and 3D concept visualization, so you can walk the house before it exists. Material and finish selections follow, along with the technical coordination that keeps the design buildable. When a project calls for architectural or engineering services, we collaborate with trusted professionals and stay actively involved throughout. You are making decisions, not chasing information.

Minor changes are sometimes possible early in construction, but significant changes after work has begun affect both timeline and budget. We invest heavily in the pre-construction phase specifically to resolve decisions before they become expensive. The more thoroughly we plan together upfront, the smoother the build goes. We’ll be direct with you about the implications of any change requested mid-construction.

We build throughout Jacksonville and the surrounding First Coast, namely Duval, St. Johns, Nassau and Clay counties. We have particular experience in historic and established neighborhoods where new construction requires sensitivity to existing streetscape and architectural context and we’re also active in newer communities and coastal areas, including the Beaches and St. Johns County.

We’re a high-touch custom builder, not a volume operation – and that changes your whole experience. Production and tract builders work at volume with standardized plans and limited options. We take on a smaller number of projects at a time, so you get more direct involvement from our principals, more flexibility in how we approach each build and a higher standard of finish throughout. Your project gets our full attention.
