โš ๏ธ Safety Checkpoints & Warnings

๐Ÿ“‹ Step-by-Step Guide (6 Steps)

1

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.

๐Ÿ‘๏ธ Camera AI Checkpoint
  • โ€ข A clean, flat perimeter outlined in sharp gray concrete
  • โ€ข An uninterrupted dark oak wood ground floor base
๐Ÿ›‘ Watch Out For
  • โ€ข Miscounting the perimeter dimensions, causing the cantilevered upper floor to misalign later
  • โ€ข Leaving uneven terrain that interferes with pool excavation
โš ๏ธ Safety Note: Flick F3 to confirm local light levels remain above 0 across the entire footprint to stop creeper spawns.
2

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.

๐Ÿ‘๏ธ Camera AI Checkpoint
  • โ€ข Sturdy box frames standing 5 blocks total height from ground level
  • โ€ข Solid gray accent panels on the rear boundary walls
๐Ÿ›‘ Watch Out For
  • โ€ข Making the ceiling height 3 blocks instead of 4, creating a cramped interior feel
  • โ€ข Placing white concrete diagonally instead of flush with the base frame
โš ๏ธ Safety Note: Deploy scaffolding rather than jumping on concrete edges to prevent unnecessary fall damage.
3

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.

๐Ÿ‘๏ธ Camera AI Checkpoint
  • โ€ข An upper structural box floating forward past the ground floor facade
  • โ€ข Clean, slabbed undercarriage beneath the protruding overhang
๐Ÿ›‘ Watch Out For
  • โ€ข Forgetting to enclose the overhang underside, leaving raw concrete bottoms exposed
  • โ€ข Overhanging by more than 4 blocks without structural balance, making the build look top-heavy
โš ๏ธ Safety Note: Keep an active water bucket on your hotbar when building cantilever edges in Survival mode.
4

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.

๐Ÿ‘๏ธ Camera AI Checkpoint
  • โ€ข Deep-tinted, flush glass walls reflecting minimal light
  • โ€ข Clean glass corners without missing connections
๐Ÿ›‘ Watch Out For
  • โ€ข Using full glass blocks instead of panes, which removes depth from the exterior facade
  • โ€ข Misplacing glass panes on the exterior edge, creating an awkward flat exterior wall
โš ๏ธ Safety Note: Keep a silk touch tool handy if building in survival to retrieve misplaced stained glass without breaking it.
5

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.

๐Ÿ‘๏ธ Camera AI Checkpoint
  • โ€ข A smooth white roof deck with hidden ambient lighting
  • โ€ข A secure glass-railed outdoor terrace on the middle tier
๐Ÿ›‘ Watch Out For
  • โ€ข Placing full quartz blocks on the roof instead of slabs, adding unnecessary bulk
  • โ€ข Neglecting roof lighting, leading to mob spawns directly overhead
โš ๏ธ Safety Note: Ensure the balcony glass rail is at least 1 full block high to prevent accidental walking off the edge.
6

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.

๐Ÿ‘๏ธ Camera AI Checkpoint
  • โ€ข Completely flat, illuminated pool water with zero active flow currents
  • โ€ข A polished patio border alternating between dark planks and manicured hedges
๐Ÿ›‘ Watch Out For
  • โ€ข Failing to fill every surface block with water, resulting in downward vortex currents
  • โ€ข Placing leaves directly against doors, blocking player entry paths
โš ๏ธ Safety Note: Avoid digging too close to redstone lines or torch mounts to prevent water spillage breaks.
