Start with the approved floor plan, not a visual guess
A thin wall is not automatically removable, and a drawing shared in a property listing is not sufficient for construction approval. HDB states that renovation contractors must submit the flat's floor plan showing the proposed work when applying for renovations that require evaluation, including wall demolition.
The practical sequence is to identify the proposed opening or removal, compare it with the relevant floor plan, review adjoining services and structural elements, then submit the proposed work through the required renovation-permit process.
How common wall types should be treated
| Element | Practical starting point | What this means |
|---|---|---|
| Reinforced-concrete structural wall, column, beam or slab | Do not plan to remove or tamper with it. | HDB lists removal of structural members as disallowed building work. |
| Internal lightweight partition wall | It may be considered, subject to written approval. | HDB requires approval for partial or complete demolition or alteration of internal lightweight partition walls. |
| Non-load-bearing reinforced-concrete element | Approval and professional supervision may be required. | HDB's building-work guidelines specify approval and supervision requirements for this category. |
| Household-shelter wall | Do not treat it as an ordinary partition. | Household-shelter walls and components are subject to specific restrictions. |
| Unknown or concealed condition | Stop and verify before continuing. | If steel bars are discovered during approved partition-wall demolition, HDB's guidance says work must stop and HDB must be informed. |
What must happen before hacking begins
- Engage a renovation contractor listed in HDB's Directory of Renovation Contractors for HDB renovation work.
- Mark the proposed wall changes clearly on the relevant floor plan.
- Submit the renovation-permit application and supporting information required for evaluation.
- Wait for prior written approval before any partial or complete wall hacking begins.
- Use the certified workers and supervision required by the approved scope.
- Keep the approved plan and conditions available to the people carrying out the work.
How Essentia approaches layout reconfiguration
We begin with what the household wants the space to support: circulation, privacy, daylight, storage and the relationship between rooms. We then test those ambitions against structural, approval and construction constraints. This prevents an attractive concept from becoming an impractical or unapprovable plan.
A good outcome may involve removing a permitted partition, changing a doorway, adding a new lightweight division or solving the same need through carpentry and furniture planning. Hacking is a means, not the objective.
