LANDED HOUSE BUILD CHECKLIST (MALAYSIA)
FOR ARCHITECT + CONTRACTOR
- SITE & ORIENTATION (MANDATORY DESIGN INPUT)
- House oriented North–South (avoid west-facing main glass walls)
- Minimise west-facing windows (afternoon heat control)
- Design for natural wind flow (cross ventilation)
- Identify slope & drainage flow before final layout
- Ensure no flood risk during heavy rain
- PASSIVE COOLING DESIGN (VERY IMPORTANT)
- Cross ventilation in every room (windows on opposite walls where possible)
- High ceiling design minimum 10 ft (prefer 11–12 ft living area)
- Staircase designed as air “chimney effect” (hot air escape)
- Roof ventilation gap / ridge vent included
- West-facing walls protected with shading or buffer rooms
- Trees/shading space planned on west side of house
- HEAT CONTROL CONSTRUCTION
- Roof insulation (foil + thermal layer mandatory)
- Light-coloured roof material or heat-reflective coating
- Heat-resistant exterior paint
- Insulated ceiling for all upper rooms
- Minimise direct sun glass exposure on west side
- WINDOWS & NATURAL LIGHT
- Large windows on North/South sides
- Avoid excessive west-facing glazing
- Natural daylight design (reduce need for artificial lights)
- Provision for blackout curtains in bedrooms
- Optional: tinted or double-glazed glass for master bedroom
- ELECTRICAL DESIGN (VERY IMPORTANT)
- DB BOARD (Distribution Board)
- Separate circuits for:
- Lighting (per floor / zone)
- Sockets (per room)
- Aircond (each room dedicated)
- Kitchen heavy load
- Outdoor lighting
- Water heater
- Extra breaker slots (future expansion)
- Space reserved for smart breaker upgrade (future-proofing)
- WIRING INFRASTRUCTURE
- Extra conduit pipes in all rooms (future smart upgrades)
- LAN cable points in:
- Living room
- TV area
- Study room
- Master bedroom
- Extra wall socket points (minimum 20–30% more than standard)
- Dedicated power point for router + mesh WiFi system
- SMART HOME READINESS
- Neutral wire available in all switch boxes (for smart switches)
- Smart switch compatible wall boxes installed
- Ceiling power points prepared for smart lighting
- Motion sensor wiring points in:
- Toilets
- Corridor
- Outdoor porch
- Central control point space (living room recommended)
- SOLAR READINESS (FUTURE PROOF)
- Roof orientation suitable for solar installation
- Clear roof area reserved for panels (no obstruction design)
- Conduit pipe from roof → DB board (pre-installed)
- Space near DB board for inverter installation
- Ground space reserved for future battery system
- WATER & DRAINAGE SYSTEM
- Proper drainage slope away from house
- Rainwater harvesting pipe routing included
- Space reserved for water tank (backyard/side)
- Kitchen grease trap included
- Separate plumbing for garden irrigation system
- OUTDOOR DESIGN
- Shade trees planned on west side
- Backyard space for utility + ESG systems
- Outdoor lighting points installed (front + back + side)
- Motion sensor-ready outdoor lighting points
- Garden irrigation piping provision
- ROOM LAYOUT FUNCTION DESIGN
- Living room designed for airflow + entertainment zone
- Bedrooms placed away from west heat exposure where possible
- Kitchen isolated from main airflow path (heat control)
- Bathrooms stacked vertically (for plumbing efficiency)
- Staircase positioned for ventilation flow (not blocked core)
- FUTURE EXPANSION (VERY IMPORTANT)
- Structural allowance for future extension (if needed)
- Extra electrical capacity reserved in DB
- Spare conduit pipes in walls and ceilings
- Roof structure allows possible solar expansion
- Space reserved for smart system upgrades
- ENERGY EFFICIENCY TARGET
- Design optimized for minimal aircond usage during daytime
- Ceiling fans planned in ALL rooms
- Natural lighting reduces daytime electricity use
- House designed to reduce heat gain first (before adding tech)
- COMMON THINGS NOT TO MISS
- Enough power sockets per room (avoid extension overload)
- Proper placement of WiFi router + mesh nodes
- Outdoor waterproof electrical points
- Proper ventilation in bathrooms
- Utility room for DB + inverter + control systems
- FINAL INSTRUCTION TO ARCHITECT
- 👉 “Design the house with passive cooling + energy efficiency as the first priority, and ensure all electrical and structural systems are future-ready for smart home and solar integration.”
RESULT OF THIS DESIGN
If followed properly, your house will:
- ✔ Stay cooler naturally
- ✔ Reduce aircond usage significantly
- ✔ Be ready for smart home upgrades anytime
- ✔ Support solar system in future
- ✔ Have lower long-term electricity cost
- ✔ Be easier to maintain and upgrade
