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.
- 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
- 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)
- 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
- 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
- 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)
- 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
- 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
- OUTDOOR & LIFESTYLE DESIGN
- Garden space
- Shade trees for cooling
- Outdoor relaxing area
- Lifestyle zones
- BBQ area
- Outdoor seating
- Kids play area (if relevant)
- 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.
- 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
- 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?”
- 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
