What Sets Us Apart

The Features That Make a Bigfoot HomeUnmistakably Yours

This is where we go beyond building a beautiful house. Hidden doors, rooftop decks, imaginative playrooms, themed rooms, and hand-painted murals — each one engineered and detailed to last, not just to impress on day one. Below is what it really takes to build each one: the design possibilities, the honest budget ranges, the space it needs, and the things we plan for before the first board goes up.

Bookshelves that swing open. Panels that vanish into the wall.

Hidden Doors & Secret Rooms

Concealed passages and private rooms engineered so seamlessly into the architecture that you'd never know they were there — until you show them off. From a hinged bookcase revealing a private study to a full secret staircase behind cabinetry, these are the details that make a home unforgettable.

Approximate Investment

Single hidden door panel$1,500 – $2,940

Bookcase / cabinetry door with room behind$3,000 – $8,100

Full secret room or passage system$9,000 – $27,000+

Ranges are starting guidelines for planning only — every project is quoted from real selections and site conditions.

Space Requirements

Clear wall run of at least 4 ft for a door, 8 ft+ for a bookcase
Unobstructed wall cavity or adjacent unused space to open into
Sufficient swing clearance for the door or shelving
Structural header to carry the load around the opening

Build Considerations

Best planned during framing — retrofitting is possible but costs more
Concealed or magnetic latch hardware must be specified early
Electrical and HVAC re-routed clear of the passage
Heavy-duty pivots for shelving doors up to several hundred pounds

Design Possibilities

Hinged full-height bookcase swinging into a studyWall-panel flush door with matching trimSecret staircase or basement access behind cabinetryWine room or panic room concealed behind a mirror or pantry

“A hidden door's only as good as its hinges and its secret. Spec the pivot hardware up front, and make sure nobody finds it 'til you want them to.”

— Hank

Your roofline, turned into a destination.

Rooftop Decks

Elevated outdoor living with panoramic views, built-in fire features, weatherproof decking, and structural railing systems designed to turn an unused roof into your favorite room in the house — with sunset views you can't get anywhere else.

Approximate Investment

Access + basic deck over a flat roof$10,000 – $22,500

Finished deck with railings, lighting & pergola$15,000 – $54,000

Rooftop oasis with fire feature, kitchen & glass rails$20,000 – $135,000+

Ranges are starting guidelines for planning only — every project is quoted from real selections and site conditions.

Space Requirements

Structurally rated roof system or engineered reinforcement
Safe code-compliant access — stair or rated ladder
Roof membrane and drainage designed for foot traffic
Guardrail height and perimeter fall-zone clearance

Build Considerations

Structural engineering is non-negotiable — the roof must carry the live load
Roofing membrane, flashing, and drainage must be detailed for foot traffic
Gas, water, and electrical runs routed up before the deck goes down
Wind exposure drives railing, pergola, and fastener selection

Design Possibilities

Composite or hardwood decking over a TPO roof membraneFrameless glass guardrails for unobstructed viewsBuilt-in gas fire feature and outdoor kitchenPergola with integrated lighting and shade

“A rooftop deck is one of the best returns on a view you'll ever spend money on — but only if the structure underneath was built for it. Get the engineer out there first.”

Indoor treehouses, rope bridges, and climbing lofts.

Imaginative Playrooms

Play spaces engineered to spark wonder and grow with your family for years — climbing walls, rope bridges, lofts with overlooks, and themed structures built to real construction standards so they're as safe as they are magical.

Approximate Investment

Loft platform with access ladder$3,000 – $9,000

Treehouse / climbing loft with bridge & slide$6,000 – $24,750

Full themed play environment with custom structures$10,000 – $67,500+

Ranges are starting guidelines for planning only — every project is quoted from real selections and site conditions.

Space Requirements

Ceiling height of 9 ft+ for lofts, 10–12 ft for multi-level structures
Adequate floor area and fall-zone clearance around climbing features
Structural framing rated for the live loads of a loft and its occupants
Visibility from the main living area for supervision

Build Considerations

Lofts and bridges require structural design beyond standard floor loads
All climbing and slide features must meet residential fall-zone safety
Soft-close, rounded edges, and non-toxic finishes throughout
Plan lighting and outlets so it stays usable as kids grow

Design Possibilities

Two-story treehouse with rope-bridge crossingClimbing wall leading to a loft overlookCargo-net ascent and enclosed slide descentThemed castle, jungle, or mountain base structure

“Build the loft like it's holding adults, not just kids — because it will. Over-engineer the framing and round every edge. That's how a playroom lasts a decade instead of a summer.”

— Hank

04 / 05

Step into a story your whole family lives in.

Themed Rooms

Fully immersive, realized environments built around a narrative — a woodland cabin, an explorer's lodge, a vintage tavern game room, or a galaxy bunker. Every surface, fixture, and detail designed to transport you the moment you walk in.

Approximate Investment

Single themed bedroom or accent space$3,000 – $18,000

Full themed room with millwork & lighting$10,000 – $42,750

Immersive multi-room environment$15,000 – $112,500+

Ranges are starting guidelines for planning only — every project is quoted from real selections and site conditions.

Space Requirements

Dedicated room or wing with controlled lighting and acoustics
Clear ceiling height for false beams, canopies, or scenic ceilings
Wall and floor area for applied millwork and scenic treatments
HVAC and electrical sized for added lighting and enclosed space

Build Considerations

Detailed scenic design and material sourcing drive the timeline
Applied millwork and faux finishes require specialty trades
Lighting design is central — dimming, color, and concealed fixtures
Resale-neutral core construction lets the theme layer be removed later

Design Possibilities

Woodland cabin with live-edge timber and stoneExplorer's lodge with maps, brass, and built-in curiositiesVintage tavern game room with reclaimed wood and pub lightingGalaxy or nautical environment with star-field ceiling

“A themed room is pure joy — but build the bones neutral so the next family can love it too. We design the structure to last a hundred years; the theme just rides on top.”

— Hank

Hand-painted walls that become signature moments.

Custom Murals & Artwork

Hand-painted murals and bespoke artistry that turn ordinary walls into one-of-a-kind moments — tailored to your taste, your home's character, and the story you want to tell. From a child's nursery comic wall to a sweeping dining room landscape.

Approximate Investment

Single accent wall mural$1,000 – $2,700

Full-room mural with custom design$3,000 – $11,250

Multi-wall or ceiling mural commission$5,000 – $33,750+

Ranges are starting guidelines for planning only — every project is quoted from real selections and site conditions.

Space Requirements

Smooth, primed wall surface free of defects
Adequate lighting — natural and accent — to showcase the work
Ceiling-height access or scaffold for elevated pieces
Protected, low-traffic placement for longevity

Build Considerations

Surface prep and primer make or break the finished mural
Design approval and concept rounds add lead time
UV-resistant, archival-grade paints for lasting color
Clear protective topcoat for washable, durable finish

Design Possibilities

Hand-painted botanical or landscape muralComic-book or storybook wall for a kid's roomAbstract gold-leaf accent behind a feature bedTrompe-l'œil architectural or scenic ceiling

“A mural is the cheapest magic in the whole house per square foot. Pick the right wall, prep it right, and let an actual artist do the work. It'll outlast every trend.”

How a Feature Gets Built

From Wild Idea to Built-In Detail

A custom feature isn't bolted on at the end — it's designed into the bones of your home. Here's the path each one takes.

Dream It

Tell us the feature you've always wanted. We listen for the story behind it and sketch what's possible on your lot and in your budget.

Design It In

Our architects and engineers integrate the feature into the structural plans — loads, clearances, concealed hardware, and the finishes that make it disappear.

Engineer It

Lofts, rooftop decks, and hidden passages get real structural design. Nothing decorative is load-bearing by accident — it's built to hold up.

Build It Right

We build it into the framing and finish schedule so it lands as part of the home, not an afterthought — inspected before it's ever covered up.
