Checklist of What To Consider Before Building A House

Here’s a complete checklist of what to consider before building—in the order that actually matters. 

1. LAND & SITE CONDITIONS (MOST IMPORTANT) 
• Orientation (critical for Malaysia climate) 
• Avoid strong west-facing main windows (afternoon heat) 
• Prefer house aligned North–South 
• Decide where morning sun vs afternoon sun enters 
•  👉 This alone can change your cooling cost significantly. 
•  Drainage & flood risk 
• Check if area floods during heavy rain 
• Natural slope of land 
• Where water flows during storms 
• Wind direction 
• Identify prevailing breeze direction 
• Plan window placement for cross ventilation
2. HOUSE DESIGN FUNCTION (HOW YOU LIVE) 
•  Lifestyle planning Ask: 
•  Do I work from home? 
• How many people live here? 
• Do I host guests often?
•  Room requirements 
• Number of bedrooms (now + future) 
• Guest room needed? 
• Study room / office? 
• Space needs 
• Car porch size (1–3 cars?) 
• Outdoor space / garden 
• Storage room (very important but often ignored) 
3.  COMFORT & CLIMATE DESIGN (VERY IMPORTANT IN MALAYSIA) 
•  Cooling strategy (before aircond) 
• Cross ventilation design 
• Ceiling height (10–12 ft ideal) 
• Window placement for airflow 
•  Heat control 
• Roof insulation (mandatory) 
• Light-coloured roof 
• West wall protection (trees / shading) 
•  Natural lighting 
• Maximise daylight (reduce electricity) 
• Avoid too much west sunlight glare 
4.  ELECTRICAL & SMART SYSTEM PLANNING 
•  Circuit planning (very important but often ignored) 
•  Separate: 
•  Lighting circuits 
• Socket circuits 
• Aircond circuits 
• Kitchen heavy load 
• Outdoor circuits 
• Smart home readiness 
•  Plan early for: 
•  Extra wiring conduits 
• LAN cable points (not just WiFi) 
• Smart switch boxes 
• DB board space for future upgrades 
• Solar readiness 
• Roof orientation suitable for solar 
• Space for inverter near DB 
• Future battery storage space 
5. WATER & DRAINAGE SYSTEM 
• Rainwater harvesting 
• Roof gutter planning 
• Tank placement area 
•  Water pressure system 
• Pump location 
• Pipe routing efficiency 
• Waste water 
• Kitchen grease trap 
• Sewer flow direction
• Septic system (if applicable) 
6.  STRUCTURE & MATERIALS 
•  Wall & roof materials 
• Heat-resistant roofing material 
• Insulated walls (important in Malaysia heat) 
• Windows 
• Double-layer glass (if budget allows) 
• Anti-heat tinted windows 
• Secure but ventilated design 
7. FUTURE PROOFING (MOST PEOPLE MISS THIS) 
•  Expansion planning 
• Can you extend house later? 
• Space for extra rooms? 
• Staircase position (for future floor expansion) 
• Electrical expansion space 
• Extra DB breaker slots 
• Spare conduits in walls 
• Empty pipe routes for future cables 
• Smart home evolution 
• Start simple but scalable 
• Don’t block future upgrades 
8.  OUTDOOR & LIFESTYLE DESIGN 
•  Garden space 
• Shade trees for cooling 
• Outdoor relaxing area 
• Lifestyle zones 
• BBQ area 
• Outdoor seating
•  Kids play area (if relevant) 
9.  BUDGET & COST PLANNING 
•  Split budget properly: 
• Structure (foundation + walls) 
• Roof + insulation 
• Electrical system 
• Plumbing 
• Interior finishing 
• Smart/ESG upgrades (optional phase) 
•  👉 Most people overspend on finishing and underinvest in structure. 
10.  COMMON MISTAKES TO AVOID 
•  Ignoring sun direction 
•  No future electrical planning 
•  Not enough windows for airflow 
•  Weak roof insulation 
•  No outdoor shading 
• No spare pipes/conduits 
• Designing before lifestyle planning 
11.  SIMPLE DECISION FRAMEWORK 
•  Before building, ask: 
•  “Will this house be cool naturally?” 
•  “Will this house waste or save energy?” 
•  “Can I upgrade this house later easily?” 
•  “Does this match my real lifestyle?” 
12. FINAL SUMMARY 
•  A well-planned landed house in Malaysia is built on 4 pillars: 
•  ✔ Climate-first design (heat + airflow) 
• ✔ Energy-efficient structure (not just gadgets) 
• ✔ Future-ready electrical system 
• ✔ Lifestyle-driven layout
