1/8" (0.125") Deep Groove (Dado) Routing & Partition Height Engineering
Integrated wood joinery system: Interior walls slide directly into 1/8" deep floor and ceiling grooves, locking 90° square with zero visible cleats!
Why 8-1/4" (8.25") instead of 8.00"? Cutting 1/8" deep grooves into the top of the floor deck and underside of the ceiling deck allows the partition panels to seat securely 1/8" into both surfaces. If cut at 8.00", the partitions would only bridge 7-3/4" between the groove bottoms, reducing the clear room height! Cutting partitions to 8-1/4" (8.25") maintains exactly 8.00" (8 ft scale) of clear ceiling height!

Set blade to 1/8" height. Take first pass along near line, nudge fence 1/8", and take second pass to clean out 1/4" groove.
Use a 1/4" solid carbide down-cut spiral bit set to 1/8" depth. Down-cut spirals eliminate any surface tearout on Baltic birch.
6mm Baltic birch is nominally ~0.236". Always route a scrap piece and test-fit your actual wall offcut for a snug slide-in friction fit!

Recommended Master Construction & Assembly Sequence (10 Build Phases)
Step-by-step master phasing guide tailored for 1/4" Baltic birch plywood and 1/8" (0.125") precision groove (dado) joinery.
Break down 1/4" Baltic birch into major blanks. Cut partitions D1-A, D1-B, D2-A, D2-B to 8-1/4" (8.25") high to seat into 1/8" grooves. Rip 16 ft of corner cleats.
CRITICAL: Route 1/8" deep × 1/4" wide grooves into decks A1, A2, and A3 while flat on the bench. Cut bay window, door, and triangular attic openings before assembly.
Pre-paint ceilings flat white (tape off grooves). Pre-wallpaper/paint interior walls (leave 1/8" tongues bare). Lay hardwood and tile flooring flat on decks.
Assemble Level 0 Plinth (48"×32"). Build Level 1 House Base (32"×12" + 8"×2" bay pad) elevated 1/2" on stone watertable rim. Glue base to plinth.
Erect B1, B2, and Front Facade C1. Slide dividers D1-A and D1-B into pre-cut 1/8" floor grooves on Base A1. Partitions auto-square at 90° with zero cleats!
Build 5"×1-1/2" fireplace on bench and mount to D1-B. Build 2" stairs (12 steps) and install landing at Z=6" rising forward to Z=0". Verify 1-3/8" clearance to Foyer window!
Install Deck A2, seating underside grooves over D1-A & D1-B. Slide D2-A & D2-B into top grooves of A2. Hang inside doors. Install clawfoot tub, sink & toilet while accessible!
Install Attic Floor A3, seating underside grooves over D2-A & D2-B. Install solid Front Slope E1 (34"×14-1/8") with 1" overhangs. Rear roof slope is 100% open by design, providing complete hands-on reach into the finished cathedral attic. Cap ridge with 34" decorative strip.
Install Alomejor 45° Bay Window into Living Room. Install Front Birch Door & entry steps. Install 6 standard 12-lattice windows. Install 1/8"×3/8" corner boards and drip caps.
Apply lawn turf, flagstone walk, flower beds, and garden bench on Level 0 Plinth. Inspect door swings, check attic peek-in sightlines, and apply satin clear coat.
