A Good Class Bungalow that has stood for decades often presents owners with a challenging decision. For some, the GCB reflects a family's history. For others without personal ties, the focus is on the story they wish to create in a home with its own past. Should they continue the existing narrative or start anew with a complete rebuild?

GCBs gazetted for conservation are subject to stringent requirements, making the decision straightforward. Owners of houses that are not gazetted may find themselves in a grey area regarding this difficult decision. When GCB owners approach us, they often wonder whether to renovate or rebuild a Good Class Bungalow. You may be asking yourself: should I renovate or rebuild my GCB? With ageing GCBs back in the spotlight, this question becomes more pertinent. Here, we explore considerations that can serve as a framework for guiding your decision.

 Architectural and Heritage Value

The interior of this GCB at Maryland Drive designed by one of Singapore’s architectural luminaries in the early 2000s was remodelled while retaining the exterior architecture.

 Depending on the decade in which a GCB was built, it is likely to feature architectural elements that reflect that era. From curved staircases to Art Deco windows or columns, these features hold heritage value over time. When we refresh a GCB, we study how these architectural elements can be a part of the interior design while keeping them up to date. 

Bungalows in Singapore can have any of the following styles: Early Bungalow, Victorian Bungalow, Black & White Bungalow, Art Deco Bungalow and the modern bungalow. Each has details that are worth saving. Gazetted buildings face stricter processes, but non-gazetted ones have more leeway to balance the preservation of architectural heritage in a GCB renovation with modern needs.

Structural and Physical Condition

The decision to rebuild or renovate can hinge on the structural and physical condition. Age is an indicator; the older it is, the more checks are required to ensure its structural and physical condition is suitable for renovation rather than a rebuild. These include hidden risks such as corrosion and foundation soundness, as well as outdated infrastructure such as old wiring, plumbing, and drainage. Once all of these are assessed, we help the client do a cost-benefit analysis of renovating or rebuilding a GCB.

Regulatory Matters

Site-specific constraints such as setbacks, soil strata, plot ratio, and maximum allowable heights – all shaped by URA regulations for Good Class Bungalows – can influence your decisions. If your scope requires an architect, we work closely with the architect during early-stage consultation. By having your architect and interior collaborate early on, you can avoid costly regrets you wish you had known about sooner.

Cost and Time Concerns

Cost is another consideration that points to a full rebuild, A&A works, or an interior-only update. It is also important to set aside approximately 20% of your budget as a buffer for unforeseen structural issues, especially in older homes – a common concern for anyone estimating the cost to rebuild a Good Class Bungalow in Singapore. Cost and time are also connected; a rebuild and A&A works take significantly longer than a renovation. Of note, too, the duration of a high-end GCB renovation depends on the scope of the project.

Lifestyle Considerations 

In this bungalow at Tan Boon Chong Avenue, we transformed attic into a spacious bedroom with generous storage by reconfiguring the layout.

The type of work you choose may also require you to plan living arrangements while the works go on. A full rebuild requires you and your family to vacate the property and have alternative living arrangements, while A&A works and renovations don't always require it. Both decisions affect quality of life for families in different ways, so it's important to discuss it with your design team.

Lifestyle considerations also involve how you envision living in your home after the project. If you prefer not to rebuild, consider how your GCB can be upgraded to modernise layouts and improve comfort. The lifecycle of every GCB is unique.  An update may be necessary to adapt a home originally designed for a nuclear family into one for a multi-generational family.

Thoughts on Legacy

Tan Chin Tuan Mansion, refreshed by our team, has been in the Tan family since it was built in 1926.

While practical matters are top of mind, the emotional aspects of a home are not to be minimised. A home embodies stories, legacy and identity. When we work with owners of GCBs, we often hear that a GCB is not only a personal dream but also an intent to create an architectural legacy. For those who have inherited the home, the challenge is balancing decisions for the present with those for future generations. This is where homeowners sometimes choose to renovate to retain the original structure — a common path for those focused on preserving heritage bungalows in Singapore.

For new owners without a personal history connected to the house, legacy can mean something different. The focus shifts from preserving family history to creating a new story you want to tell. Some choose to retain the original structure to inherit a sense of history and craftsmanship they couldn't otherwise recreate. Others opt for a full rebuild to make their home truly theirs.

The Choice is Yours

For this house that was designed with bifurcated stairs, we proposed a regal design concept with a light palette for the walls to play up its sense of symmetry.

 With our years of experience designing landed properties and GCBs for UHNWIs, our clients return to us because we listen to their personal goals while considering the practical realities that shape their home's future. Ultimately, the decision to renovate or rebuild is about the kind of home you want to hand down, and to whom. The best choice balances both emotion and function.

Therefore, the next step forward has to align with your needs and vision, whether that means weighing the pros and cons of renovating versus rebuilding an ageing GCB, or trusting your instincts. Whether it's one that begins afresh on the same land or one that continues to honour the architectural character the previous owners and original architects built, neither instinct is wrong. This is not a decision to be made lightly, but one to explore with care.

Are you sitting with this decision for your own GCB? Let's discuss what makes the most sense for your home and your family.
