Patio Lanais, Sunrooms & Home Additions in Palm Beach County, FL

Homeowners in Palm Beach County, Florida, can work with Preventive Maintenance for patio lanais, existing patio-to-sunroom conversions, and home additions. We coordinate the building, windows, roofing, electrical, air-conditioning, plumbing, plans, and permits through a single-source construction model, so the project can be managed through one company.

Whether you want a covered outdoor area, an enclosed room, or additional air-conditioned living space, the first step is to inspect the property and determine which construction option fits your home, budget, and requirements.

Key Takeaways

  • Preventive Maintenance builds aluminum and conventional lanais, converts existing patios into enclosed rooms, and constructs home additions throughout its Palm Beach County service area.
  • Aluminum lanais cost about $52 per square foot and conventional wood-and-concrete lanais about $65 per square foot when built on an existing concrete slab; conversions and additions require separate assessments.
  • The average project timeline is 3–6 months, covering inspection, design, applicable HOA requirements, permitting, and construction.
  • South Florida heat, humidity, heavy rain, insects, and high-wind requirements influence material and roof decisions, so the property should be inspected before the project is priced or designed.

    • Patio Lanais, Sunrooms, and Additions for Palm Beach County Homes

    A patio lanai creates a covered outdoor living area. A sunroom conversion takes an existing patio and turns it into an enclosed room, while a home addition creates additional space as part of the house.

    These options serve different purposes. A covered lanai can provide shade and protection from rain, while an enclosed room may provide more protection from insects and weather. An air-conditioned addition can create additional indoor living space.

    The appropriate solution depends on the existing patio, slab, roof, desired level of enclosure, and whether the new space needs air-conditioning.

    Preventive Maintenance serves homeowners in Jupiter, West Palm Beach, Boynton Beach, Delray Beach, and Boca Raton, along with other eligible locations within its Palm Beach County service area.

    Patio lanais

    A patio lanai adds a covered outdoor area to an existing home. Depending on the project, the structure may use an insulated aluminum roof or conventional wood-and-concrete construction.

    Existing covered patios and lanais commonly have a concrete slab or pavers. The existing surface, structure, and proposed design need to be assessed before deciding how the new work should be built.

    For homeowners comparing the two construction options, the starting prices are approximately $52 per square foot for an aluminum lanai on an existing concrete slab and $65 per square foot for a conventional wood-and-concrete lanai on an existing concrete slab.

    Existing patio-to-sunroom conversions

    Converting an existing patio into an enclosed room can provide a more protected space without necessarily constructing an entirely new addition.

    The scope depends on what can remain from the existing structure. The roof and slab may or may not be suitable for reuse, and the project may require changes involving windows, insulation, electrical work, and air-conditioning.

    There is no single price per square foot for every conversion. An inspection is needed to establish the scope and determine which components can be retained.

    Home additions

    A home addition creates new living space connected to the existing house. Unlike a covered lanai, an air-conditioned addition is intended to function as indoor living space.

    Roof design may involve a flat TPO roof or sloped concrete tile, depending on the project. Structural connections, windows, electrical work, plumbing, and air-conditioning must be considered as part of the overall design.

    The company's indicative price for an air-conditioned addition is about $250 per square foot. Actual pricing depends on the project requirements and should be established after an inspection.

    Choosing the Right Construction Option

    Project type Main purpose Indicative pricing
    Aluminum lanai Covered outdoor living area About $52/sq. ft. on an existing concrete slab
    Conventional lanai Covered outdoor area with wood-and-concrete construction About $65/sq. ft. on an existing concrete slab
    Patio-to-sunroom conversion Enclose an existing patio Depends on existing structure and required upgrades
    Air-conditioned addition Create additional indoor living space About $250/sq. ft.
    New home construction Build a new home About $350/sq. ft.

    These figures are starting points, not guaranteed quotes. The lanai prices specifically assume an existing concrete slab. Conversion costs depend on the roof, slab, glass, insulation, electrical work, and HVAC requirements. Final pricing requires an assessment of the property and proposed work.

    Typical project sizes range from 12' × 20' to 20' × 20', although custom sizes are available.

    Construction Considerations in Palm Beach County

    Heat, humidity, and heavy rain

    Outdoor and enclosed spaces in South Florida must be planned for heat, humidity, rain, and insects. Material selection, roof design, enclosure requirements, and ventilation or air-conditioning needs should match the intended use of the space.

    High-wind requirements

    Florida's High Velocity Hurricane Zone requirements may be relevant depending on the property's location and the applicable building rules. Structural design, connections, materials, and permitting must be addressed for the particular project rather than assumed to be identical for every property.

    Roof connections and existing structures

    A new lanai or enclosed room must be evaluated in relation to the existing home. Depending on the design, the roof may connect through a ledger or through joists and trusses at the tie-beam. The appropriate connection depends on the structure and approved design.

    An inspection helps establish whether the existing slab, roof, and other components can be retained or whether additional work is needed.

    One Company for the Construction Process

    Preventive Maintenance coordinates the building, windows, roofing, electrical, air-conditioning, plumbing, plans, and permits through a single-source construction model.

    The typical process includes:

    1. Property inspection: Review the existing structure, site conditions, and proposed use.
    2. Design and planning: Establish the project scope, materials, roof configuration, and required work.
    3. HOA review: Address applicable HOA requirements and common HOA notices where relevant.
    4. Permitting: Coordinate plans and applicable permit requirements.
    5. Construction: Complete the approved project according to its scope and requirements.

    The average project timeline is 3–6 months. Actual timing depends on the project, design, applicable approvals, permitting, and construction requirements.
