Good Class Bungalow Renovation in Singapore – 2025 Comprehensive Guide

Good Class Bungalows (GCBs) represent the highest tier of landed property ownership in Singapore. These prestigious homes are limited in supply, located in prime districts like Nassim, Holland, and Bukit Timah, and often sit on sprawling plots of land with rich greenery. Owning a GCB is a rare privilege — but to fully maximise its value, renovation is essential.

This 2025 guide covers costs, timelines, design trends, URA regulations, and renovation strategies so homeowners can make the right decisions when transforming their GCBs. Whether you are considering an Addition & Alteration (A&A) or a full rebuild, this article provides the most detailed roadmap available online.

Understanding the Unique Nature of GCB Renovation

Renovating a Good Class Bungalow is unlike any other type of home renovation in Singapore. These properties are governed by special restrictions, and mistakes in planning or compliance can lead to costly delays.

• Minimum plot size: 1,400 sqm as defined by URA
• Height restrictions: Maximum 2 storeys plus attic
• Green coverage: At least 60% of the land must remain landscaped
• Approval requirements: A Qualified Person (QP) must submit all major works for URA and BCA approval
• Neighbourhood context: Renovations must respect the exclusivity of surrounding GCB estates

Step-by-Step Process of Renovating a GCB

1. Initial Consultation – Engage an architect or design-build firm for site assessment
2. Concept Design – Prepare 3D visuals and space planning layouts
3. Regulatory Submissions – Submit plans to URA, BCA, and obtain clearances
4. Budget & Timeline Agreement – Secure detailed quotations and milestones
5. Construction & Project Management – Execute works with consistent quality checks
6. Final Inspection & Handover – Ensure compliance, complete snag list, and handover keys

Cost Guide for Good Class Bungalow Renovation in 2025

💡 Tip: Always prepare a 10–15% contingency fund for unexpected costs such as foundation strengthening or imported marble finishing.

Design Trends for Luxury GCB Homes

1. Resort-Style Living

Infinity pools, landscaped gardens, and outdoor entertainment areas create a private retreat that mirrors resort living.

2. Contemporary Interiors

Open-plan layouts, double-volume ceilings, and natural stone finishes are increasingly popular in 2025.

3. Sustainable Smart Homes

Solar panels, rainwater harvesting, and fully integrated smart systems improve both sustainability and convenience.

4. Bespoke Carpentry & Luxury Kitchens

At SpeedyDecor, we design and fabricate custom wardrobes, luxury kitchens, and entertainment lounges tailored to GCB living.

Hidden Costs You Must Anticipate

• Soil & Foundation Works – Older plots often need piling and reinforcement
• Compliance Delays – URA submissions can extend timelines if incomplete
• Imported Materials – Long lead times and currency fluctuations affect pricing
• Neighbourhood Sensitivity – Noise and traffic management add additional costs

International Inspiration for GCB Renovations

Singapore GCBs are increasingly influenced by global luxury homes:

• Beverly Hills, USA: Floor-to-ceiling glass walls with panoramic views
• The Peak, Hong Kong: Maximising hillside plots with vertical landscaping
• Dubai Luxury Villas: Resort-style indoor-outdoor integration

These global trends are adapted to Singapore’s tropical climate, ensuring both comfort and durability.
