⚠️ Safety Checkpoints & Warnings
- • Place torches or Sea Lanterns across dark sub-floors to prevent hostile mobs from spawning inside walls.
- • Use scaffolding or keep a water bucket hot-barred on survival mode to prevent lethal fall damage from high overhangs.
- • Ensure water streams during pool construction do not wash away redstone, carpets, or temporary torches.
📋 Step-by-Step Guide (6 Steps)
Clear the Site and Mark the Foundation Grid
Clear a flat 30x25 block plot using your shovel and pickaxe. Mark the primary ground floor perimeter using Gray Concrete, laying an L-shaped base measuring 18x12 blocks on the long wing and 10x8 blocks on the adjoining wing. Fill the interior surface with Dark Oak Planks to serve as the ground-level subfloor.
- • A clean, flat perimeter outlined in sharp gray concrete
- • An uninterrupted dark oak wood ground floor base
- • Miscounting the perimeter dimensions, causing the cantilevered upper floor to misalign later
- • Leaving uneven terrain that interferes with pool excavation
Erect the Ground Floor White Concrete Framing
Raise 4-block-tall vertical pillars of White Concrete at all exterior corners of the foundation. Connect the tops of these pillars with horizontal White Concrete beams to establish an open rectangular frame with a 4-block ceiling clearance. Insert full-height Gray Concrete accent walls on the rear-facing sections for visual contrast.
- • Sturdy box frames standing 5 blocks total height from ground level
- • Solid gray accent panels on the rear boundary walls
- • Making the ceiling height 3 blocks instead of 4, creating a cramped interior feel
- • Placing white concrete diagonally instead of flush with the base frame
Frame the Cantilevered Second Story
Extend a secondary White Concrete frame that overhangs the front ground floor edge by 3 blocks to create the signature modern cantilever look. Build this upper frame 5 blocks tall, leaving large 3x4 block wall openings on the front and side facades for panoramic window installations. Bridge the gap underneath the overhang with Smooth Quartz Slabs for a smooth underside finish.
- • An upper structural box floating forward past the ground floor facade
- • Clean, slabbed undercarriage beneath the protruding overhang
- • Forgetting to enclose the overhang underside, leaving raw concrete bottoms exposed
- • Overhanging by more than 4 blocks without structural balance, making the build look top-heavy
Install Floor-to-Ceiling Black Glass Panes
Fill the large structural openings across both floors with Black Stained Glass Panes, aligning them flush with the interior edge of the frame. On corner window junctions, connect the glass panes cleanly to form seamless glass wrap-arounds. Double-check that no single-block glass gaps remain unsealed against the exterior elements.
- • Deep-tinted, flush glass walls reflecting minimal light
- • Clean glass corners without missing connections
- • Using full glass blocks instead of panes, which removes depth from the exterior facade
- • Misplacing glass panes on the exterior edge, creating an awkward flat exterior wall
Construct the Modern Balcony and Flat Roof Deck
Cover the upper roof with Smooth Quartz Slabs, placing Sea Lanterns recessed into the roof deck every 4 blocks covered by light gray carpet for hidden lighting. Create a balcony over the exposed section of the ground-floor roof using Black Stained Glass Panes as safety railings. Install Dark Oak Doors connecting the upper bedroom area directly onto the balcony terrace.
- • A smooth white roof deck with hidden ambient lighting
- • A secure glass-railed outdoor terrace on the middle tier
- • Placing full quartz blocks on the roof instead of slabs, adding unnecessary bulk
- • Neglecting roof lighting, leading to mob spawns directly overhead
Excavate and Fill the Modern Infinity Pool
Dig out an 8x4 trench 2 blocks deep alongside the ground floor patio, lining the bottom and sides with White Concrete and Sea Lanterns for an illuminated glow. Fill the perimeter with source water blocks using your bucket until the water surface is completely still, level, and flush with the surrounding patio slabs. Outline the outer patio with Dark Oak Planks and trimmed Oak Leaves.
- • Completely flat, illuminated pool water with zero active flow currents
- • A polished patio border alternating between dark planks and manicured hedges
- • Failing to fill every surface block with water, resulting in downward vortex currents
- • Placing leaves directly against doors, blocking player entry paths
