Key Takeaways
- A&A renovations allow homeowners to upgrade their spaces without rebuilding, but they must follow Singapore renovation guidelines.
- Internal layout changes and exterior upgrades are usually allowed, but structural changes require proper approval.
- All A&A works must be submitted by a Qualified Person (QP) for A&A and comply with building regulations.
If you live in a landed home in Singapore and want to update your space without tearing it down completely, additions and alterations (A&A) renovations offer a practical and cost-effective option. These works allow you to improve your home’s layout, appearance, or function whilst retaining its original structure.
However, not everything is permitted under Singapore renovation guidelines. There are clear rules on what you can change, what needs approval, and what falls outside the scope of typical A&A works. Whether you are expanding your living space or upgrading the façade, this guide will help you plan within the rules.
1. You Can Modify Internal Layouts
The good news is that most internal, non-structural changes are allowed. If you are hoping to remove a partition wall to create an open-concept living and dining area, reposition bedrooms, or combine small rooms into one, these fall well within the standard scope of A&A renovations.
These kinds of adjustments are especially popular in older properties, where room layouts may feel outdated or inefficient. For instance, many homeowners opt to reconfigure narrow kitchens or enlarge bathrooms as part of their landed property interior design upgrades. As long as the structural integrity of the building is not compromised, such internal changes can usually proceed without issue.
2. You Can Add Extensions (With Limits)
Extensions are one of the biggest draws of A&A renovations, as they allow you to increase usable space without rebuilding entirely. A common example is a single-storey rear extension, which can accommodate a larger kitchen, a home office, or even a family room. Some homeowners may also want to add a roof terrace or attic room.
However, such changes are subject to stringent landed property renovation rules. The Urban Redevelopment Authority (URA) enforces setback controls, height restrictions, and site coverage limits to ensure that extensions do not affect neighbouring properties or breach planning standards. Your renovation must also comply with fire safety and drainage requirements. This is where a Qualified Person for A&A—typically an architect or professional engineer—can guide the design and ensure that your submission meets all relevant criteria.
3. You Can Upgrade Façades and Entrances
Refreshing the front of your home can be a great way to update its aesthetics. A&A works allow for non-structural changes to your home’s exterior, including updating windows, repainting walls, replacing doors, or redesigning the entrance porch. These updates are especially useful for homeowners who want a more modern appearance or to improve curb appeal.
As long as these upgrades do not involve major structural alterations or breach zoning requirements, they can typically proceed with minimal approvals. However, if your home is within a conservation area or subject to special planning restrictions, the changes may need further clearance from the URA. A knowledgeable interior design consultant can help identify what is feasible while still achieving your aesthetic goals.
4. You Cannot Change the Building Envelope Without Approval
While some changes are allowed under A&A renovations, there are clear limits. Any proposal that involves shifting load-bearing structures, adding a new floor, or increasing the building’s gross floor area (GFA) usually falls outside standard A&A permissions.
Such works are categorised as reconstruction or redevelopment and require more extensive review by both URA and the Building and Construction Authority (BCA). Attempting to bypass these regulations can result in project delays, fines, or even the need to demolish unauthorised works. For this reason, it is important to work closely with a Qualified Person for A&A as they will know what requires submission and how to obtain the necessary approvals.
5. You Cannot Ignore Compliance and Submission Requirements
No matter how small your project may seem, all A&A works must follow the proper submission process. This includes appointing a QP to prepare and submit plans to the relevant authorities. Depending on the scope of the renovation, clearances may be needed from URA, BCA, the Fire Safety and Shelter Department (FSSD), and the Public Utilities Board (PUB).
Even seemingly minor oversights, such as neglecting fire-rated materials or exceeding setback limits, can cause costly delays. Engaging a reliable interior design consultant will not only help with visual planning but also ensure the renovation proceeds smoothly and legally from start to finish.
A&A renovations offer homeowners in Singapore the flexibility to enhance their homes without full reconstruction.
