The light in this Caribe Isle home in Bel Marin Keys is shaped by its position on the water, its two-story form, and the wide windows that face both the deck and the hills. This project is for the family living in this 2,334-square-foot house, built in 1987 on a flat, 9,361-square-foot lot, with four bedrooms, three full baths, and a three-car garage. The house’s vaulted living and dining ceilings, white horizontal siding, brick accents, and expansive waterfront deck set the tone for a remodel that brings the morning and evening light into the rooms where the household actually spends time.
The Kitchen Island and Main Floor Light
The kitchen, already updated with a quartz island and induction cooktop, sits open to the family room and the deck. The wood flooring runs through the main living areas, and the kitchen’s current layout allows for a direct route from the street entrance, through the kitchen, to the deck. In this house, the kitchen sink is positioned to take in views across the water through large windows. Before finalizing any cabinetry or appliance changes, I would stand at the existing sink and confirm that the sightline does, in fact, capture the intended view of the water and hills.
Because the induction cooktop is centered on the island, the exhaust route must be planned to vent directly to the exterior, never simply assumed through the vaulted ceiling. The mechanical design for this house should establish the path for the vent hood and determine if makeup air is required, given the central heating and cooling systems already present. The electrical service in this house, as recorded, supports central HVAC and modern appliances, but any plan to add a second oven or relocate appliances should begin with a check of the existing circuits and panel capacity.
The wood flooring in the kitchen, dining, and living areas should read as a single, continuous field. This means checking the actual floor heights and transitions at every threshold before ordering new cabinetry. Where replacement is needed, I would select a wood and finish that matches the existing planks in this house. The lighting plan should layer warm task lighting above the island, dimmable ceiling fixtures for general use, and low-glare pendants at the dining table. The large windows already bring in daylight; in this vaulted living room, I would avoid scattering recessed fixtures across the ceiling, letting the architecture and light lead.
Living, Dining, and Family Room Connections
In this house, the kitchen and family room open directly onto the uncovered waterfront deck, while the living and dining rooms enjoy their own vaulted volume and views. The living room’s cathedral ceiling and expansive windows are a defining feature, and I would keep the separation between these rooms rather than remove more walls. The family room’s interior wall is the right place for a television, so the water-facing windows remain free from glare. The dining table fits naturally between the kitchen and living room, leaving the path to the deck clear for easy indoor-outdoor flow.
Central heating and cooling, as installed in this two-story house, should be reviewed by an HVAC contractor to ensure the supply and return locations serve the open main floor and the vaulted spaces. Soft window coverings and a rug in the family room would help absorb sound and make the space comfortable without blocking the light from the windows. The main floor’s bedroom and full bath offer flexibility for guests or a household member who prefers to avoid stairs, while the three upstairs bedrooms, including the primary suite with its walk-in closet and spa-like bath, remain private retreats.
Deck, Garage, and Exterior Details
The uncovered deck, attached to both the kitchen and family room, is the direct link to the private dock and water. I would add built-in seating along the deck’s edge, after confirming the deck’s structure can support it. The exterior brick columns at the garage and side entry could be refinished in a lighter or more contemporary treatment to harmonize with the white siding. The black garage doors, currently prominent, could be replaced with modern paneled or glass options to bring the three-car garage into a more cohesive palette. The entry door, too, could be replaced with a larger, more decorative contemporary style to match the scale of the house.
The lot’s low-maintenance landscape, with mature palms and a gentle lawn, could be streamlined with more drought-tolerant and native plants, in keeping with the mild maritime climate and the lot’s flat, Xerorthents-Urban soil (0 to 9 percent slopes, per the soil survey map). The Marin County Community Development Agency requires permits for any structural, electrical, plumbing, or mechanical modifications in this unincorporated area, including changes to the kitchen, baths, or exterior (permit guidance). Cosmetic-only updates, such as painting or cabinet resurfacing, do not require permits.
This house’s main footprint is about 3,210 square feet, with three other nearby structures within 25 meters on the map. The home’s 2,334 square feet is nearly identical to the median for Bel Marin Keyes single-family homes, which means the focus here is on making the existing rooms and connections work better, not adding more area. If you live in a house like this and want to open up the light, improve the flow, and connect your everyday spaces to the water and deck, I invite you to get in touch.
