Majestic Grand Mountain Lodge with an Amazing Master Suite (Floor Plan)

4,531 square feet. Two separate second floors. And a home gym hidden between the garage bays that most people don’t even notice on the floor plan.

After reviewing thousands of mountain lodge layouts, this one from Architectural Designs does something I rarely see – it splits the upper level into two completely independent wings, each with its own staircase.

That changes everything about how this house actually lives.

Let me walk you through it room by room, but pay attention when we get to the master suite. The fireplace detail there is the kind of thing builders quietly argue about.

Specifications:

• 4,531 Heated s.f.
• 3-5 Beds
• 2.5 – 3.5 Baths
• 2 Stories

The Floor Plan:

The Numbers Behind This Mountain Lodge

Before we step inside, here’s what you’re working with. This plan comes in at 4,531 heated square feet across two stories, with flexibility for 3 to 5 bedrooms and 2.5 to 3.5 bathrooms. It includes a 4-car garage – split into two 2-car bays with a home gym sandwiched between them.

At current mountain construction rates, you’re looking at roughly $250 to $400 per square foot for a timber-and-stone build of this caliber, depending on your market.

That puts the build cost somewhere between $1.1 million and $1.8 million before land – and that’s using mid-range finishes. In resort-adjacent areas like Vail, Breckenridge, or Whitefish, those numbers climb toward $500 per square foot or more.

The plan also includes an optional lower level that could add another 1,500-plus square feet of finished space, including a media room with wet bar and additional bedrooms. That’s a significant expansion for relatively low cost since the foundation and roof structure are already there.

Here’s where the layout gets clever.

The Front Porch That Sets the Whole Tone

You pull up to this lodge and the first thing that registers isn’t the size – it’s the weight.

Stone columns anchor the entry, heavy timber framing stretches overhead, and the porch is deep enough that you could furnish it like an outdoor room. This isn’t a decorative landing pad. It’s a transitional space that slows you down before you step inside.

That’s intentional. Mountain lodge architecture uses the entry sequence to shift your mindset from arrival to rest. The covered depth protects you from rain, snow, and direct sun while giving your eyes time to adjust from bright daylight to the interior.

Most front porches on plans this size are afterthoughts – four feet of concrete with a couple of columns. This one actually earns its square footage.

But the room behind that front door is the one that sells this entire plan.

The Sunken Great Room That Adds a Foot of Ceiling You Didn’t Pay For

You step through the entry and the floor drops.

The great room is sunken – a design move that instantly adds perceived ceiling height without actually raising the roofline. When you pair that drop with two-story windows and vaulted, beamed ceilings overhead, the room reads as massive.

Here’s what most people don’t realize about sunken living areas: they define boundaries in an open floor plan without using a single wall. You feel the transition from the entry level to the living space physically, in your knees and your inner ear. That subtle shift tells your brain you’ve entered a different zone.

Designers surveyed in 2025 actually named sunken living rooms the number one comeback trend – and in a lodge layout like this, the feature makes even more sense because the dropped floor creates a cozy, anchored feeling against all that vertical glass.

The two-story windows flood the space with light while the exposed beams overhead add visual weight that keeps the room from feeling cold. You can hear the difference in a room like this – the vaulted ceiling changes the acoustics, giving conversations a warmth that flat ceilings can’t match.

Take a guess – how tall do you think those ceilings reach at the peak?

Most people estimate 16 feet. In a vaulted great room this size, you’re likely looking at 20 feet or more at the ridge. That’s the kind of volume that makes a 4,500 square foot home feel like 6,000.

This next room surprised even me.

The Double-Island Kitchen That Actually Earns Both Islands

You round the corner from the great room and the kitchen opens up with something you almost never see in plans under 5,000 square feet – two full islands.

Most dual-island kitchens are just showing off. This one isn’t. The layout uses one island for prep and one for serving and seating, which means the cook’s workflow stays completely separate from the gathering traffic.

The walk-in pantry sits just steps from the primary prep island. No hauling ingredients across the room. The counter space wraps the perimeter, giving you an unbroken work surface that a professional kitchen designer would approve of.

Here’s the builder detail worth noting: dual islands require careful plumbing and electrical planning. You’ll likely want a prep sink in one and power outlets in the other for small appliances. Budget an extra $3,000 to $5,000 for the additional plumbing rough-in compared to a single-island kitchen.

But the payoff is real.

This kitchen can handle a holiday dinner for twenty while keeping the cook sane. The sight line from the prep island to the great room means whoever’s cooking never misses the conversation.

Most people scroll right past the next space. Don’t.

The Dining Situation That Gives You Two Completely Different Moods

This plan doesn’t make you choose between casual and formal dining – it gives you both, and positions them in a way that actually makes sense.

The casual dining area sits adjacent to the kitchen, wrapped in windows on three sides. Morning light pours in while you eat breakfast. The views do the decorating for you.

In a mountain setting, this room essentially becomes a solarium – surrounded by landscape on three walls with natural light that shifts throughout the day.

Then there’s the vaulted formal dining room at the front of the house, separated enough from the kitchen to feel intentional. The vaulted ceiling here echoes the great room’s volume, giving dinner parties a sense of occasion without being stuffy.

Homes with both casual and formal dining consistently outperform single-dining-area homes in the luxury market. At the $1M-plus price point, buyers expect options. This plan delivers them without wasting square footage on a room that sits empty 350 days a year – because the casual area handles daily life.

I saved the best room for a reason.

The Master Suite With a Fireplace That Changes How You Use the Room

You step into the master suite and the first thing you feel is distance.

This room is deliberately positioned away from the main living zones, giving it a hush that the rest of the house doesn’t have.

The fireplace anchors one wall. Not a decorative insert – a real focal point that radiates warmth on mountain nights when the temperature drops to single digits. Double doors open directly onto the deck, which means you can step from a warm bed to cold mountain air in three seconds flat.

That kind of indoor-outdoor connection in a master suite is something architects typically charge premium design fees for.

The walk-in closet here isn’t a standard reach-in with some extra shelving. It’s a room. Builders who’ve worked with plans this size estimate master closets at 80 to 120 square feet in a layout like this – enough space for a center island dresser if you want one.

A bedroom fireplace in a mountain home adds roughly $4,000 to $8,000 for a gas unit with stone surround. But it’s one of the top three features luxury buyers mention when touring homes in this price range. On a per-dollar basis, it’s one of the strongest ROI moves in the entire plan.

The Master Bathroom That Feels Like a Separate Wing

The en-suite bathroom amplifies everything the bedroom promises.

The proportions here are generous enough that the space doesn’t just accommodate a double vanity and soaking tub – it gives each fixture breathing room. You’re not bumping elbows at the sinks in the morning.

In a mountain lodge of this caliber, expect:

• heated tile floors
• a walk-in shower with frameless glass
• natural stone finishes that tie back to the exterior materials

The bathroom alone in a plan like this can account for $25,000 to $50,000 of the finish budget, depending on material choices. But it’s the room that sells the master wing – and at resale, a spa-caliber master bath is non-negotiable in this price category.

But there’s one design choice in this house that divides people.

The Two Separate Second Floors That Most Plans Don’t Dare Attempt

This is the feature that makes this plan genuinely unusual.

Instead of one continuous second floor reached by a single staircase, this lodge splits the upper level into two completely independent zones – each with its own dedicated staircase.

One staircase near the kitchen leads up to the craft room and playroom. The other, off the foyer, leads to two bedrooms. These upper-level zones don’t connect to each other at all.

They’re essentially two separate wings stacked above different parts of the first floor.

Why does this matter? Privacy. A teenager doing homework in the bedroom wing can’t hear a five-year-old playing in the playroom wing. A guest staying in one of the upstairs bedrooms has their own staircase and doesn’t walk through your living space at midnight on the way to the kitchen.

The trade-off is cost. Two staircases means two sets of framing, railing, and finish work. Expect to add $8,000 to $15,000 compared to a single-staircase plan. But for families who actually live in mountain homes full-time – or host guests regularly – that money buys something no open floor plan can deliver: genuine acoustic separation between zones.

How much do you think that dual-staircase design adds to the total square footage of the house?

Most people guess it eats up 200 square feet. The actual footprint for two sets of stairs is closer to 120 to 140 square feet total – because each staircase is compact and purpose-built for its wing.

Now here’s what the floor plan doesn’t show you.

The Home Gym Between the Garage Bays That Most People Miss Entirely

Look at the floor plan again. Between the two 2-car garage bays, there’s a space labeled for a home gym. This is one of the smartest uses of dead space I’ve seen in a residential plan.

The area between garage bays is usually wasted – a wall, some mechanicals, maybe a storage closet. This plan turns it into a dedicated fitness room with a location that actually makes sense.

It’s isolated from the living spaces, so no treadmill noise bleeds into the great room. It’s on a concrete slab, so there’s no worrying about floor reinforcement for heavy equipment. And it shares the garage’s HVAC zone, which simplifies climate control.

At roughly 200 to 300 square feet, it’s enough room for a full cardio setup plus a weight rack and bench. And because it sits at ground level with garage-grade flooring underneath, you can drop weights without worrying about the structure beneath you.

That’s a practical advantage that basement and second-floor gyms can’t match.

After reviewing thousands of layouts, this detail still stands out.

The Exterior That Earns Every Inch of That Mountain Backdrop

The exterior of this lodge isn’t just attractive – it’s engineered to sit in a landscape. The blend of natural stone, timber framing, and steeply pitched rooflines borrows from classic mountain vernacular while keeping the proportions clean enough to feel current.

Multiple outdoor spaces wrap the home, including the deck off the master suite and the front porch entry.

In a mountain setting, outdoor square footage is almost as valuable as indoor space for six to eight months of the year.

Decks and covered porches at this scale typically add $15 to $25 per square foot to build – a fraction of interior space – but they contribute disproportionately to how the home feels and how it photographs for resale.

The roofline deserves attention too. Steep pitches shed snow load efficiently, which in mountain building codes is a structural requirement – not just an aesthetic choice.

A roof designed to handle 40 to 60 pounds per square foot of snow load costs more in engineering and materials, but it prevents the ice dam and structural failures that haunt poorly designed mountain homes.e to dream big. Can you see yourself here, living your mountain retreat dream in the Grand Mountain Lodge?

BONUS: The Optional Lower Level Most Buyers Don’t Realize Exists

If you scroll back up to the floor plan, you’ll notice this home includes an optional lower level. Most people skim right past it because it’s labeled “optional” – but finishing that lower level might be the single best value play in this entire plan.

The lower level adds space for:

• additional bedrooms
• a media room with a wet bar
• a second exercise room

Because the foundation walls, footings, and roof are already built and paid for, the cost to finish a lower level is dramatically less than adding the same square footage as an addition.

Builders estimate finishing a walkout basement at $50 to $100 per square foot compared to $250-plus for new construction. On a plan this size, that lower level could add 1,500 square feet of living space for $75,000 to $150,000 – space that would cost $375,000 or more if built as a new wing.

That wet bar and media room combination is also one of the features mountain home buyers specifically search for. If you’re building this plan with any thought toward future resale, finishing the lower level isn’t optional – it’s the move.

What would you change about this plan? Would you build it as-is, or would you finish that lower level from day one?
