One-Level Beach House – 4,068 Sq Ft, 4 Bedrooms, 4.5 Bathrooms with Courtyard Garage & Luxury Lanai

This one-level beach house offers approximately 4,068 square feet of heated living space, delivering a luxurious coastal layout that feels bright, open, and made for effortless indoor-outdoor living.The design includes 4 bedrooms, 4 full bathrooms + 1 half bath, an attached 3-car courtyard-entry garage (~782 sq ft), and a beautifully planned rear lanai with outdoor kitchen (~516 sq ft).

The overall footprint measures approximately 74′-6″ wide by 95′ deep, giving the home a broad, upscale presence with plenty of room to stretch out. 0This is the kind of house that feels like a permanent vacation, except your laundry still lives there too.

Exterior & First Impressions

From the outside, this home leans into elegant coastal luxury with a polished, resort-inspired look.

Its broad one-story footprint, layered roofline, and courtyard-style garage arrangement give it the kind of presence that feels upscale without becoming stiff or overly formal. The design is categorized in several overlapping styles including Coastal, Coastal Contemporary, Florida-Style, and Transitional, which gives you a good sense of its clean, breezy architectural personality. 1 This is not a tiny flip-flops-and-beach-chair cottage. This is the beach house that clearly has opinions about stone countertops.

Open Living Core – Bright, Airy & Built Around the View

Step inside and the home opens into a large shared living space designed to feel bright, expansive, and deeply connected to the outdoors.

One of the biggest highlights of the layout is the great room, which opens directly to the kitchen and is filled with natural light, helping the whole home feel airy and inviting. The plan also lists a two-story great room among its special features, giving the main living space a dramatic sense of volume even though the home itself is a single-story design. 2This central area is ideal for:

• Everyday family life that stays connected
• Entertaining without crowding
• Making the home feel even larger than its already generous square footage

It’s open in the right way. Not “echoing wine glass showroom” open. Just genuinely spacious and livable.

Kitchen & Dining – The Coastal Command Center

The kitchen sits right where it belongs: at the center of everything. In a home like this, the kitchen becomes much more than a place to cook. It becomes the social engine room, snack headquarters, and the place where everyone somehow ends up during every gathering.

This plan includes:

• A massive kitchen island
• A nearby hidden butler walk-in pantry
• An adjoining breakfast nook overlooking the rear lanai
• A separate formal dining room for more intimate meals

3That combination gives the home excellent flexibility. You get the casual openness people love now, plus a more polished dining space for holidays, guests, or those rare evenings when dinner is plated instead of negotiated.

Study / Home Office – Quiet, Useful & Very Easy to Appreciate

One of the most practical features in this layout is the dedicated study, which can easily double as a home office. It’s one of those spaces that adds immediate real-life value because even if you don’t need it every day, you will almost certainly end up using it. 4

That room works beautifully as:

• A remote work office
• A reading or planning room
• A quiet flex space
• A household “do not disturb unless urgent” zone

Homes with a true study tend to age very well because modern life has become increasingly allergic to not having one.

Primary Suite – Private, Luxurious & Thoughtfully Separated

The primary suite occupies the right wing of the home, which gives it a more private, retreat-like feel away from the rest of the living spaces. Better still, the layout uses a split-bedroom design, helping keep the owner’s suite comfortably separated from the secondary bedrooms. 5

Inside, the suite is designed to feel like a proper getaway and includes:

• A private entrance to the rear lanai
• A spa-like en suite bathroom
• Dual walk-in closets
• Dual commode rooms
• A freestanding tub
• An oversized shower

6That bathroom setup is not playing around. It has the kind of confidence usually reserved for boutique hotels and people who own matching robe sets.

Secondary Bedroom Suites – Guest-Ready & Exceptionally Comfortable

This home includes three additional bedroom suites, and each one comes with its own full bathroom. That’s a major luxury upgrade that makes the home especially comfortable for larger families, long-term guests, or anyone who appreciates a little more privacy and less hallway traffic. 7

That setup is ideal for:

• Guests who stay comfortably without feeling tucked into leftovers
• Older children or teens
• Multi-generational living flexibility
• A more polished and upscale daily routine

This is one of those features that quietly makes the entire house feel more premium.

Laundry, Mudroom & Everyday Function

This home also does a very good job with the practical support spaces that make a house feel easier to live in over time. The 3-car garage opens directly into the laundry / mudroom, creating a smarter transition point between the outside world and the interior of the home. 8

That helps with:

• Keeping clutter and daily traffic better contained
• Making laundry easier to access
• Creating a more functional daily entry sequence

It’s not glamorous, but it is extremely useful. Which is often better.

Lanai & Outdoor Living – The Best Seat in the House Might Be Outside

This home is clearly designed for an indoor / outdoor lifestyle, and nowhere is that more obvious than in the rear lanai. The plan includes approximately 516 square feet of lanai space, plus an outdoor kitchen that helps turn the entire rear side of the home into a true extension of the living space. 9

That makes this house especially good for:

• Outdoor dining
• Weekend entertaining
• Relaxed evenings in warm weather
• Making the whole home feel brighter and more open

And because both the breakfast nook and the primary suite connect beautifully to this area, the lanai doesn’t feel like a decorative extra. It feels like part of the home’s actual heartbeat.

Garage, Dimensions & Structural Details

The attached 3-car garage offers approximately 782 square feet and uses a courtyard entry, which gives the home a more elegant front-facing appearance while still providing strong everyday practicality. 10Additional structural details include:

• Stories: 1
• Foundation: Slab
• Exterior walls: Block / CMU (main floor), optional 2×6
• Width: 74′-6″
• Depth: 95′
• Max ridge height: 30′
• Primary roof pitch: 4:12
• Roof framing: Truss

11That construction profile makes a lot of sense for a coastal or warm-weather home where durability and clean structural efficiency matter.

Functional Features That Make Life Better

• Open-concept living for better flow and natural light
• 4-bedroom, 4.5-bath layout with strong privacy
• Primary suite in its own wing with private lanai access
• Three additional bedroom suites, each with private bath
• Massive kitchen island and hidden butler pantry
• Formal dining room plus breakfast nook
• Dedicated study / home office
• Rear lanai with outdoor kitchen for indoor-outdoor living
• Attached 3-car courtyard garage
• Main-level laundry and mudroom entry

Estimated U.S. Build Cost

Typical U.S. construction costs for a luxury coastal or beach-style home of this size generally range between $210 and $420 per square foot, depending on region, structural requirements, finish quality, hurricane/wind code needs, and outdoor living upgrades.For this 4,068 sq ft home, that places the estimated build cost around:

• Low estimate: $854,000
• High estimate: $1,708,000
• Mid-range realistic build: $1,020,000 – $1,340,000

Because this design includes a courtyard garage, luxury bath layout, lanai, outdoor kitchen, and coastal-style construction considerations, actual costs can drift upward quickly once the phrase “since we’re already doing it” starts appearing in design meetings. 12
