Steps For Building House

10 Steps to Build a New House on a 30×40 Site

Follow this straightforward sequence on a 30×40 plot in Bengaluru. Doing it right from day one saves cost, time and headaches.

Step 1: Site Assessment & Permits

  • Get the plot surveyed and soil tested — critical for footing size and structural budget.
  • Check local setbacks, floor area ratio (FAR), and other by-laws — avoid surprises later.
  • Fix the basic layout (stair, car park, duct zones) before you move dirt.

Step 2: Design & Plan Freeze

  • Select layout-type: 2BHK or 3BHK depending on family and budget.
  • Space efficiency matters: avoid wasted corridors or odd angles on 30×40.
  • If you want Vastu, place main rooms accordingly — see our Vastu guide below.

Step 3: Permits & Approvals

  • Submit drawings and get clearance before construction begins — structural, plumbing, electrical.
  • A professional architect ensures drawings meet regulations and avoids rejection/notices.

Step 4: Foundation Work

  • Excavate as per soil report and plan grid — correct footing size and reinforcement.
  • Ensure good compaction and proper raw materials — weak foundation = higher cost later.

Step 5: Framing & Structure

  • Erect columns and beams as per grid — avoid shifting during work.
  • For duplexes, plan load transfers and slab depth early — that decides cost.

Step 6: Services Installation

  • Plumbing, electrical and ducts go in before walls — locate sleeves and shafts correctly.
  • Stack toilets vertically where feasible — reduces plumbing run and reduces leaks.

Step 7: Roofing & External Shell

  • Close the building to weather: roof, doors, windows first — internal works follow.
  • Choose materials that match climate and budget — avoid over-spec’ing on 30×40 unless needed.

Step 8: Interior Finishing

  • Install flooring, gypsum/plaster, windows and basic fixtures — multirole furniture if space is tighter.
  • Fix wardrobe/bed sizes early so switches and windows don’t clash later.

Step 9: Exterior & Landscaping

  • Use leftover setback for garden or patio — even in 30×40 a smart landscape makes difference.
  • Driveway, parking and external lights planned now avoid later scrambling.

Step 10: Inspection & Handover

  • Walk through structure, finishes, services and fitments — tick off defects early.
  • Get final approvals, occupancy clearances (if needed) and schedule move-in.
