The Floor Plans:

Front Porch

When you reach the house, the front porch feels like an open invitation. It’s spacious enough for rocking chairs or a cozy swing.

The covered design with sturdy columns provides a sense of protection from the elements, and the crisp white trim pops against the warm stone and earthy siding.

I love how this entryway instantly sets a relaxed, welcoming mood that fits right in with the mountain setting.

Entry

Step inside and you’re greeted by a bright, open entryway. There’s plenty of space to welcome guests comfortably, and the clear sightlines into the main living areas spark curiosity.

I’ve always felt that a generous entry makes a house feel more gracious, and this one really does.

Office

Just off the entry, the office is designed for real productivity. It gets plenty of natural light and sits at the front of the house, making it easy to imagine long work sessions or creative projects.

Because it’s close to the front door, this space is perfect for anyone needing a semi-private work zone that’s still connected to daily life.

Guest Suite Two

To your left, down a short hall from the entry, you’ll find Guest Suite Two.

This is more than just a guest bedroom. There’s a large walk-in closet and a private bath.

If you have extended family or friends staying over, they’ll appreciate the privacy and comfort.

I think placing this suite near the entry is a great decision, giving guests a sense of independence while keeping them close to the action.

Guest Suite One

Just past Guest Suite Two is Guest Suite One, which offers even more space, its own walk-in closet, and an en suite bath.

The smart window placement brings in plenty of sunlight, so the room never feels isolated.

You can use it for guests, in-laws, or even as a flexible second master. I like how this area adapts to whatever you need.

Family Room (Main Level)

Step into the main family room and you’ll instantly notice the tall ceilings and open feel.

There’s a wall of windows looking out onto the deck, flooding the space with daylight.

The fireplace on one side creates a cozy, lived-in vibe that invites you to relax.

I can easily picture game nights, movie marathons, or lazy afternoons here. The double doors make it easy to move between indoors and the deck.

Deck

Head outside from the family room and you’re on the deck, which stretches across the back of the house.

This is the spot for grilling, stargazing, or sipping your morning coffee. The views are framed by the gabled rooflines and timber beams, giving you a true mountain experience in every season.

Dining

Back inside, the dining area sits between the family room and kitchen. It’s an ideal spot for everyday meals or big gatherings.

Large windows keep things bright, and the open layout encourages conversation from one end of the table to the other.

There’s enough room for a table that seats ten or more, so holiday dinners won’t feel crowded.

Kitchen

The kitchen stands out with a huge center island and high-end appliances along the wall.

Bar stools at the island make it great for quick breakfasts or hanging out while cooking.

I think this layout is perfect for families who love to cook together, thanks to the generous workspace and easy access to both the dining area and pantry.

Pantry

Behind the kitchen, the walk-in pantry is a real bonus. Shelves line the walls, ready for bulk groceries, kitchen gadgets, or even a coffee station.

If you enjoy cooking or hosting, this kind of storage is a game changer. It keeps everything handy but out of sight, so your kitchen always looks tidy.

Mud Room

Past the kitchen is the mud room, a practical space that makes everyday life more manageable.

You’ll find hooks for coats, cubbies for backpacks, and a bench for boots. This drop zone is perfect for busy families, especially with the garage entrance right next door.

Laundry (Main Level)

The laundry room is next to the mud room, with space for both a washer and dryer, plus counter space for folding clothes.

There’s even a utility sink for muddy gear or quick rinses after outdoor adventures. I appreciate that this setup keeps laundry messes out of the main living spaces.

2-Car Garages (Main Level)

Off the mud room, you have two separate 2-car garages. This design keeps vehicles and storage organized, with extra space for bikes, tools, or an ATV.

Direct entry into the mud room means you can unload groceries or gear without crossing through your living room.

Powder Room (Main Level)

The powder room is close to the family room and easy for guests to access. Its central location means visitors won’t need to walk through your private spaces.

Stairs to Upper and Lower Levels

In the middle of the main floor, an open staircase connects you to both the upper and lower levels. The stairway design feels natural, making it easy to move throughout the house.

Let’s head upstairs and see what the upper level has in store.

Loft

At the top of the stairs, the loft is surprisingly spacious. It’s not just a hallway landing—it’s a full living area, perfect for a homework spot, reading lounge, or playroom.

With views down to the family room and windows on two sides, it feels both connected and private.

Bedroom Four

On one side of the upper floor, you’ll find Bedroom Four. This room is generous in size, with a private bath and a large closet.

It could work well for a teen, older child, or as another guest suite. I like how this bedroom has a bit of separation from the others, giving its occupant extra privacy.

Bedroom Five

Down the hall, Bedroom Five offers a roomy layout and its own en suite bath.

There’s plenty of space for a queen bed and extra furniture. It’s a great fit for siblings or visiting relatives.

Bedroom Six

Just beyond Bedroom Five is Bedroom Six, which mirrors the same comfort and privacy. With a private bathroom and a sizable closet, this room gives everyone in the family a comfortable place to settle in.

Laundry (Upper Level)

A second laundry room upstairs means you won’t have to haul baskets up and down the stairs. It’s right in the bedroom wing, making laundry day much more convenient.

Covered Deck (Upper Level)

Step out onto the covered deck and enjoy the mountain air. This upper-level outdoor space is quieter than the main deck, making it perfect for reading, stretching, or quiet conversations.

Primary Bedroom

Set apart from the other bedrooms for privacy, the primary bedroom occupies the rear wing of the upper floor.

It’s a real retreat, offering enough space for a king bed and a sitting area.

Two walls of windows fill the room with light, and the private deck brings in lovely backyard views.

To me, this suite captures what mountain living is all about—open, peaceful, and a little bit indulgent.

Primary Bath and Walk-In Closet

The primary bath combines function and luxury with double vanities, a soaking tub, walk-in shower, and a separate water closet.

The walk-in closet is large, with built-in shelving for easy organization. If you enjoy starting and ending your day in a peaceful setting, you’ll love this setup.

Bridge and Open to Below

A bridge connects the two bedroom wings and looks down into the family room below, giving you a real sense of the home’s scale. The open areas upstairs keep things bright and connected, so you’ll always feel part of the action.

Let’s head back down to explore the lower level.

Family Room (Lower Level)

Downstairs, the lower-level family room spans the back of the house. There’s space for a pool table, sectional sofa, and plenty of games.

This area is perfect for movie nights or big gatherings. Sliding doors open to a covered patio, making it easy to blend indoor and outdoor living.

Patio

Just off the family room, the patio gives you even more space to relax. It’s covered, so you can enjoy the outdoors in any season.

It’s an ideal spot for a fire pit or picnic table.

Guest Bedroom (Lower Level)

The lower level includes another guest bedroom, complete with a walk-in closet and full bath.

This space works well for overnight guests or as a quiet room for an older child.

The privacy here really stands out, making it feel like a retreat of its own.

Home Theater

If you love movies, you’ll appreciate the home theater in its own corner of the lower level.

The room has no windows, so you get a true theater experience. There’s even an A/V closet to keep all the equipment organized.

Unfinished Storage

Finally, two large unfinished storage rooms line the lower level. I always think these are some of the most underrated spaces in a home this size.

You’ll have plenty of room for holiday decorations, seasonal gear, or anything else you want to put away until next year.

With sunlit decks, peaceful retreats, and spaces for both entertaining and everyday living, this home’s layout balances gathering areas with private escapes. Each level offers something special, making it easy to imagine growing into this house for years to come.
