Build steps
- 1
Measuring and Checking Installation Location
≈ 15 minMeasure the installation space for the miniature house-shaped doghouse (700×600×800mm). Confirm width of the installation space, ensure passage clearance (600mm or more), and check door opening range.
MeasureW 700 mmMeasureSTEP 1 / 13Tip
- Place so not under rain gutters or over drainage.
- Leave at least 20mm gap between wall and furniture for easier cleaning.
- Avoid boundary between wooden deck or soil and ground surface to prevent wobbling.
Watch out
- Cannot install if installation width less than 700mm. Pre-measurement is important.
- Outdoor locations with heavy traffic - protruding placement to foot area risks tripping.

Creating a Cutting List for Materials
≈ 30 minCut cedar plank 19mm thick into front and back boards (19×120×700mm) ×14 pieces each, and side boards (19×120×600mm) ×14 pieces each. Bottom board is lauan plywood 12mm thick (12×562×662mm) ×1 piece. Corner posts are 2x4 lumber (38×89×800mm) ×4 pieces. Using home center paid cutting service is convenient.
CutUse the in-store cut serviceCutSTEP 2 / 13Tip
- Cedar planks vary widely in knots and warping. Select by handling each board.
- Corner post length 800mm includes front/back board height (120×4=480mm) plus 20mm allowance.
- When using cutting service, can specify grain direction alignment for better appearance.
Watch out
- Cut ends of cedar plank absorb water easily. Apply wood preservative generously later.
- 2x4 lumber actual size is 38×89mm. Specify '38×89' when ordering cuts (nominal vs actual size differs).
- 3
Sanding All Materials
≈ 40 minSand using #120 grit then #240 grit sandpaper. Cedar boards are soft and prone to warp and splinters; carefully sand edges and surfaces. Chamfer 2x4 corner posts to smooth and prevent catching shoes or bumping legs.
Sand#120SandSTEP 3 / 13Tip
- Cedar wood grain is coarse; sand along grain to avoid raising splinters.
- Sand cut ends flat with #120 then smooth with #240 grit. Skipping this causes uneven paint absorption.
- Using an orbital sander reduces sanding time to one-third; rental services are available.
Watch out
- Sanding produces large amounts of dust. Work in ventilated places like balconies or garages.
- Do not paint before removing dust; powder left causes rough surface. Remove with air duster or damp cloth.
- 4
Standing up and Temporarily Fixing Corner Posts
≈ 25 minVertically stand four 2x4 posts and place at four corners of the workbench. Temporarily fix with clamps to workbench ensuring top and bottom are level. Confirm vertical alignment with a level. Measure spacing between posts as 600mm front to back and 300mm left to right (inside dimensions) with measuring tape.
Build the frameTighten joints firmlyAssembleSTEP 4 / 13Tip
- Check verticality with level on two sides (front and side) aiming for zero on both.
- Concrete floors or cushioned flooring are uneven; place plywood underneath to create flat work surface.
- Arrange posts with knots aligned facing the same direction for better appearance.
Watch out
- If even one post is off vertical, all attached boards will tilt.
- Be consistent measuring inside or outside of posts to avoid 5-10mm errors in spacing.
- 5
Attaching Front and Back Boards (Starting from Bottom)
≈ 40 minPlace first cedar board horizontally at lowest front position, apply wood glue to corner posts, and fix with coarse-thread screws 65mm, two screws per side (four total). Insert about 5mm ventilation gap (approximate thickness of a chopstick) between boards as stacking continues. Out of total 10 boards, place 5 on front and 5 on back.
Build the frameTighten joints firmlyAssembleSTEP 5 / 13Tip
- 5mm ventilation gap prevents moisture buildup on shoes; tightly joining boards causes mold.
- Use chopsticks to maintain uniform gaps.
- Drill pilot holes (φ4mm) into corner posts before screwing to prevent splitting.
Watch out
- Failing to drill pilot holes causes cedar boards to split.
- Driving screws too deep dents board surface; stop flush with surface.
- 6
Attaching Side Boards (Left and Right)
≈ 35 minAttach side boards (19×120×600mm) ×14 pieces each side similarly with ventilation gaps. Attach 5 boards per side. Adjust front and back board positions so wood ends meet precisely at corners before attaching side boards. Measure front-to-back diagonal lengths with tape measure, ensuring both diagonals are equal while fixing.
Build the frameTighten joints firmlyAssembleSTEP 6 / 13Tip
- Unequal diagonals cause parallelogram distortion; use clamps to correct until equal.
- Side boards fit inside front and back boards; offset pilot holes slightly away from edges of front/back boards.
- For better corner finish, miter cut 45 degrees on corner posts before fastening if desired.
Watch out
- Misaligned ventilation gaps between side and front/back boards look uneven.
- Diagonal difference over 5mm prevents smooth storage use inside.
- 7
Processing and Installing Bottom Board
≈ 25 minOn lauan plywood 12mm bottom board (562×662mm), drill nine φ20mm ventilation holes evenly arranged in a 3×3 grid. Holes must be at least 50mm from edges and 100mm apart. Insert bottom board under assembled frame and fix with coarse-thread screws 45mm to four corner posts.
Drill a holeφ20mmDrillSTEP 7 / 13Tip
- Ventilation holes allow shoe bottom moisture to escape; do not reduce number.
- Use hole saw for neat holes; wood drill bit is acceptable.
- Bottom side of board facing ground is not visible; no edge tape necessary.
Watch out
- Warped bottom board prevents tight fit with posts; check flatness beforehand; reverse and clamp with screws to correct if large warp.
- Placing holes too close to edge weakens strength; keep at least 50mm margin.
- 8
Final Check of Right Angles and Diagonals
≈ 15 minCheck assembled box for right angles and diagonal lengths. Measure all four internal angles with a carpenter's square to confirm deviation from 90 degrees. Measure two diagonals with tape measure to confirm difference is within 2mm. If misaligned, loosen screws and straighten with clamps before re-tightening.
InspectNo wobble ✓InspectSTEP 8 / 13Tip
- Diagonal difference indicates assembly error; under 2mm is acceptable for practical use.
- Measurement must be done on flat, level surface to avoid errors.
- Check for any loosened screws by finger pressure thoroughly.
Watch out
- Ignoring distortion causes doors (lids) to open and close poorly.
- Loose screws risk wobbling and collapse under shoe load later.
- 9
Painting Undercoat and Sanding
≈ 15 minLightly sand entire assembly with #240 grit and clean off dust with damp cloth before painting. Smooth screw heads and edges as well. Outdoor grade preservatives like Keshira Decol or Osmo Color are suitable.
Sand#240SandSTEP 9 / 13Tip
- Cedar absorbs paint intensively; plan for two coats.
- Apply extra paint on cut ends; exposed fibers absorb heavily.
- Apply Keshira Decol by rubbing in with cloth; more uniform than brush.
Watch out
- Skipping sanding causes uneven paint and fuzziness.
- Painting over residual dust causes rough surface texture.
- 10
First Coat Painting
≈ 30 minApply Keshira Decol or water-based paint over entire surface. Brush or wipe paint in one direction along grain, soak for 15-20 minutes, then wipe excess off with dry cloth. Paint ventilation gaps by inserting brush diagonally to avoid missed spots. Allow natural drying for over 2 hours.
PaintWatco oil / varnishPaintSTEP 10 / 13Tip
- Keshira Decol's 'paint and wipe' method preserves wood texture.
- Paint accumulating in ventilation gaps slows drying; wipe to expedite.
- Work outdoors or ensure good ventilation for fumes removal.
Watch out
- Forgetting to wipe leaves tacky residue lasting days.
- Applying thick coat causes uneven drying and peeling later; thin two coats are essential.
- 11
Intermediate Sanding and Second Coat Painting
≈ 25 minAfter first coat is dry, lightly sand surface with #320 grit sandpaper (intermediate sanding). Remove dust, then apply second coat thinner than first, wipe off excess similarly. Allow full curing for 24 hours.
PaintWatco oil / varnishPaintSTEP 11 / 13Tip
- Lightly sand only roughness; avoid removing paint film.
- Two coats greatly improve wood preservation; do not skip second coat.
- Dry in dust-free area.
Watch out
- Excessive sanding removes first coat.
- Skipping second coat halves preservative effect, especially critical outdoors with moisture exposure.
- 12
Feet Pads and Waterproofing Measures
≈ 15 minAttach felt pads or non-slip rubber to bottom ends of corner posts. If placing directly on ground, elevate by 10cm with bricks or blocks. For tile floors, use silicone pads to prevent slipping.
Fix to the wallAnchor to studsInstallSTEP 12 / 13Tip
- Felt absorbs water and soils easily; rubber or silicone recommended outdoors.
- Pads are essential at four corner posts; skipping center causes tilt.
- Allow ventilation for one week post-installation to dissipate paint fumes.
Watch out
- No pads risk floor damage and slipping on wet surfaces.
- Silicone pads sometimes have weak adhesive; use strong double-sided tape for reliability.
- 13
Final Inspection and Shoe Storage
≈ 15 minConfirm all screws are tight, ventilation gaps uniform, and paint evenly applied. Check wobbles with level; adjust pad thickness if needed for levelness. Avoid placing heavy items until paint fully cures after 1 week. Store only dry shoes inside.
Done!Done — nice work!DoneSTEP 13 / 13Tip
- Wipe wet shoes before storing to prevent moisture buildup.
- Store shoes only up to 80% capacity to maintain ventilation.
- Monthly ventilation by emptying and drying with fan extends life.
Watch out
- Placing wet shoes before paint cures leaves shoe-shaped stains on finish.
- Overfilling causes board deformation from forced storage.
Warnings
- ⚠️Wood preservative coating is essential for outdoor use (recoating recommended annually)
- ⚠️Use stainless steel screws (iron screws will rust)
- ⚠️Drill pilot holes before screwing to prevent wood splitting
- ⚠️Use paint safe for pets to lick (water-based urethane paint recommended)
