Custom home builder in Miami.

A custom home in Miami starts long before the first pour.

A custom home is one of the largest investments an owner will make, and in South Florida it is also one of the most technical. Wind design, impact-rated openings, flood elevations, drainage and municipal design review all shape what can be built and how long it takes. Ballagas Construction is a Florida State Certified General Contractor (CGC1530999) that builds luxury custom homes across Miami-Dade and Broward for owners who want the project managed with discipline from the first plan review to final turnover.

We are intentionally selective. Taking on a focused number of homes allows leadership to stay close to every site, every decision and every inspection. You will not be handed from one project manager to the next.

Constructability review before pricing.

Every custom home starts with the drawings. Before we price a project, we review the architectural, structural, civil and MEP sets together, along with the specifications, survey and any geotechnical information. We look for missing details, conflicts between disciplines and field conditions the drawings do not yet address. Finding those issues on paper costs far less than finding them after concrete is placed.

That review becomes the basis of a detailed, line-item scope: what is included, what is excluded, what is carried as an allowance, which items are alternates and which decisions still belong to the owner. A proposal built this way explains the scope instead of hiding assumptions, which makes it easier to compare and easier to manage.

A schedule built on real sequencing.

Custom homes in Miami are governed by permitting, procurement and inspections as much as by field labor. We build the schedule around the actual sequence of the work: permit submittals and product approvals, long-lead items such as impact windows and doors, foundation and structural shell, roof dry-in, rough trades, close-in inspections, finishes, punch and turnover. Long-lead items are identified early so they arrive when the building is ready for them, not weeks after.

Working with your architect and design team.

We work alongside the architect, structural engineer, interior designer and landscape architect, not around them. Questions are documented, answered and tracked. When an owner selects and purchases finishes directly, we keep a decision log so lead times, rough-in requirements and installation standards are clear before the field team needs them. The goal is to protect the design intent of the home while keeping the build organized.

What happens on site.

• Mobilization, site security, layout and temporary controls, with a plan for access, staging, deliveries and dumpsters that respects the neighbors.
• Foundation, structural shell and roof dry-in, with trade coordination before major milestones such as pours, framing, rough-in and drywall.
• Inspection readiness checks before each inspection, so issues are corrected before an inspector finds them.
• Weekly progress updates with photos, schedule notes and the decisions needed next.
• Written change orders, priced and approved before any changed work proceeds.

Owner-led from start to finish.

Ballagas Construction is owner-led. Ernesto and the leadership team stay directly involved in planning, pricing and field decisions, and communication stays simple: you always know what is happening, what changed, what is pending and what decision is needed next. Our five-step process explains how each phase is managed.

Where we build.

We build custom homes throughout Miami-Dade and Broward, including Miami Shores, Coral Gables, Miami Beach, Pinecrest, Coconut Grove and Fort Lauderdale. Current work includes Kaēlo Residence, a new two-story home in Miami Shores now in glazing installation and interior finishes, and Casa Arborēa, our new-home development in Miami Shores, breaking ground in early 2027.
