Bungalow Renovation KL 2026: Costs, Process & What to Expect
Updated: Jul 18
A bungalow renovation in KL or Selangor is the most complex and highest-stakes residential renovation you can undertake. More space, more trades, more decisions, longer timelines — and more opportunity to create something truly exceptional.
Quick Answer: Bungalow renovation in KL costs RM 200,000–RM 600,000+ depending on size, age, and scope. A standard bungalow (3,000–4,000 sq ft) with full interior renovation typically costs RM 250,000–RM 400,000. Heritage or older bungalows with structural issues can cost significantly more.
Studio D3 has completed bungalow renovation projects across Petaling Jaya, Damansara, Bangsar, Ampang, Puchong, and Shah Alam. Here's what you need to know before starting yours.
How Much Does a Bungalow Renovation Cost in KL & Selangor?
Scope | Estimated Budget (2026) |
Partial renovation (selected areas only) | RM 150,000 – RM 300,000 |
Full renovation (mid-range finishes) | RM 280,000 – RM 550,000 |
Full renovation (high-end finishes) | RM 500,000 – RM 1,000,000+ |
Full renovation + extension | RM 400,000 – RM 1,500,000+ |
Bungalow renovation costs vary enormously depending on built-up area, age of the property, scope of structural work, finish quality, and the level of customisation. A 3,000 sqft 1980s bungalow in Petaling Jaya with a full structural overhaul and premium finishes is a very different project from a cosmetic refresh of a newer 4,000 sqft bungalow in Puchong.
How Long Does a Bungalow Renovation Take?
Scope | Estimated Timeline |
Cosmetic refresh (paint, flooring, selected carpentry) | 10 – 16 weeks |
Full renovation (no structural changes) | 20 – 32 weeks |
Full renovation with structural changes | 28 – 48 weeks |
Full renovation with extension | 36 – 60 weeks |
Unlike condo or terrace renovations, bungalow renovations require significantly more coordination between trades — structural engineers, architects (for extensions), plumbers, electricians, air conditioning specialists, landscape contractors, and interior carpenters all need to sequence their work carefully.
Key Decisions in a Bungalow Renovation
1. Structural Assessment First
Before any design work begins on a bungalow — particularly one built before 1990 — commission a structural assessment. Aging bungalows in Malaysia often have: undersized electrical capacity for modern loads, original galvanised plumbing that has corroded, roof structures that need reinforcement or replacement, and foundation settling that has caused cracking. Knowing what you're working with before designing saves costly mid-project discoveries.
2. The Extension Question
Many bungalow owners use the renovation as an opportunity to extend — adding a rear extension, a pool deck, an additional bedroom wing, or converting the car porch. Extensions require plan submission to the local authority (DBKL, MBPJ, MPSJ, MBSA, etc.) and typically take 3–6 months for approval. If you're considering an extension, start this process before the interior design is finalised.
3. M&E (Mechanical & Electrical) Strategy
A bungalow renovation almost always requires a full electrical upgrade — new main distribution board (DB), new wiring throughout, new lighting circuits, dedicated circuits for kitchen appliances, air conditioning, and EV charging if relevant. The same applies to plumbing: older bungalows often have complex, non-standard plumbing runs that need complete replacement. Budget for full M&E replacement as a baseline assumption, not an optional extra.
4. Air Conditioning — Central vs. Split Units
A bungalow with 4–6+ bedrooms across two floors is an ideal candidate for a central air conditioning system — one compressor serving multiple indoor fan coil units, controlled by a centralised system or individual zone controls. Advantages: lower energy consumption, fewer wall penetrations, cleaner aesthetics, and single maintenance contract. The decision about AC type must be made before false ceilings are designed, as the piping routing determines ceiling depth and layout.
5. Landscape and Exterior
A bungalow sits on its own land — the exterior matters as much as the interior. A well-planned bungalow renovation addresses the full site: facade, gate, car porch, front garden, rear garden, side passages, and any auxiliary structures (guardhouse, utility rooms). Neglecting the exterior after investing heavily in the interior is one of the most common regrets in bungalow renovations.

Frequently Asked Questions
Do I need an architect for a bungalow renovation?
For purely interior renovations (no extensions, no structural wall removal), a licensed interior designer and contractor can handle the project without an architect. For extensions, new structures, or removing load-bearing elements, you need a licensed architect to prepare and submit plans to the local authority. Studio D3 works with trusted architects for projects requiring plan submission.
Can I live in my bungalow during the renovation?
For a full bungalow renovation involving heavy hacking, dust, chemical use, and multiple trades working simultaneously — we strongly recommend moving out. For a phased renovation where one section is completed before another begins, some homeowners stay in the unrenovated wing. This requires very careful planning and clear communication with the contractor about safe access zones.
How do I phase a bungalow renovation if I can't do it all at once?
Phase strategically: do all structural, electrical, and plumbing work in Phase 1 — these run through the whole building and doing them twice is expensive. Phase 2 can be finishes (tiles, carpentry, painting). The worst phasing approach is doing one floor fully and leaving the other untouched — because M&E work has to be redone when you return to the second floor.
