Your home should grow with your life. Webman Builders is South Florida's trusted home addition contractor — building seamless room additions, vertical expansions, and suite additions that feel as if they've always been part of your home. We work exclusively on luxury single-family residential additions throughout Miami-Dade and Broward County, with deep expertise in South Florida's permitting requirements, flood zone construction standards, and HOA architectural review processes.

Types of Home Additions We Build
Master Suite Additions — The Most Valuable Addition in South Florida
A luxury master suite addition is the single most popular and highest-value home addition in South Florida. We design and build primary suite additions that include a generously proportioned bedroom, a spa-quality master bathroom (freestanding tub, frameless shower, double vanity, heated floors), a custom walk-in closet system, and often a sitting room or private outdoor access. A well-designed master suite addition typically adds $200,000–$500,000 in market value to a South Florida luxury home.
Second-Story Additions — Maximum Square Footage Without Sacrificing Yard
When your lot doesn't allow horizontal expansion, a second-story addition is the answer. Webman Builders designs and builds full second-story additions — adding an entirely new floor to your existing single-story home. We handle all structural engineering, foundation assessment, and temporary weatherproofing during construction. Most popular in North Miami Beach (33179) and Golden Beach where lot sizes and setbacks limit ground-floor expansion.
Great Room & Living Room Expansions
Extend your primary living area outward for open-plan entertaining. We knock down rear walls, extend slabs, and create seamless great room additions that connect your kitchen, dining, and living areas in one flowing space — with large format sliders opening to your outdoor living area.
In-Law Suite & Guest Suite Additions
A fully independent living space on your property — separate entrance, kitchenette, bedroom, and bathroom. Fully permitted through Miami-Dade and Broward County as an accessory dwelling unit (ADU) or guest suite. Increasingly valuable as South Florida's multigenerational living trends continue.
Home Office Additions
A dedicated, acoustically isolated home office with proper ventilation, electrical capacity, structured cabling, built-in storage, and private access. Built to professional standards for South Florida's growing population of executives and entrepreneurs who work from home full-time.
Garage Additions & Expansions
Single-to-double garage conversions, new detached garages with finished space above, and oversized garages for car collections. We design and permit garage additions through Miami-Dade and Broward County and ensure drainage, electrical, and HVAC requirements are met for Florida's climate.

Home Additions — Frequently Asked Questions
How do I know if my home can support a second story addition?
We conduct a structural assessment of your existing foundation, slab, and wall systems as part of our pre-project consultation. In some cases, foundation reinforcement is required before vertical expansion — we identify and price this upfront so there are no surprises mid-project.
Will a home addition match my existing home's style?
Yes. Our team carefully studies your existing roofline, exterior finishes, window styles, and interior architectural details before designing the addition. We specify matching materials and work with your home's existing architectural language so the addition looks purposeful, not tacked on.
Do you handle HOA architectural review for additions?
Yes. We prepare all documentation required for HOA architectural review committees, including renderings, material specifications, and setback compliance documentation. We submit on your behalf and manage the review process.
How much does a home addition cost in South Florida?
Home additions in South Florida typically cost $200 to $500+ per square foot depending on type, finish level, and structural complexity. A master suite addition of 500-800 sq ft typically runs $180,000–$400,000. A second story addition for a full 2,000 sq ft floor typically runs $400,000–$900,000+. Webman Builders provides a free, written estimate for every project.
Can I add a pool and outdoor living area at the same time as the addition?
FAQ A: Yes. We frequently coordinate home additions with pool construction and outdoor living projects. Combining scopes often reduces overall cost and minimizes disruption to your property.
