Understanding the Costs of Building a Landed House in Singapore: New Erection, Reconstruction, and Addition & Alteration Works

Building or modifying a landed house in Singapore can be an exciting journey, but it also requires careful financial planning. Whether you’re considering a new erection, reconstruction, or addition and alteration (A&A) works, understanding the associated costs is crucial for a smooth and efficient process.

Here’s an overview to guide property owners on what to expect in terms of costs for these types of projects.

  1. New Erection Costs

A new erection involves building a house from the ground up. This is often chosen by owners looking to design a completely new structure tailored to their preferences and lifestyle.

Key Factors Affecting Cost:

Land Size and Plot Ratio: Larger plots or those with higher plot ratios incur higher costs due to the scale of construction.

Design Complexity: Multi-level designs, modern architecture, or unique features (e.g., an attic, basement, or cantilever structures) can increase costs.

Construction Materials and Finishes: Premium materials like marble or high-end wood, as well as luxury fixtures, significantly impact the budget.

Regulatory Compliance: Costs for permits, planning approvals, and compliance with URA and BCA regulations are non-negotiable.

Estimated Costs:
For a 2-3 storey landed house, the cost typically ranges from $300 to $500 per square foot (psf). For a more accurate figure, budgeting $1.4M to $1.8M for a terrace house

  1. Reconstruction Costs

Reconstruction involves demolishing and rebuilding substantial portions of an existing house while retaining some structural elements. This is an ideal choice for property owners who wish to modernize their home without entirely starting from scratch.

Key Factors Affecting Cost:

Extent of Demolition: The more demolition required, the closer it approaches a full new erection cost.

Structural Upgrades: Existing structures might require reinforcement to support new designs, adding to costs.

Integration Challenges: Merging old and new structures seamlessly often involves higher design and construction costs.

Estimated Costs:
Reconstruction typically costs between $250 to $450 psf, depending on the retained structure’s condition and the complexity of the rebuild.

  1. Addition and Alteration (A&A) Works Costs

A&A works focus on making changes or extensions to an existing structure, such as adding a new room, converting a car porch, or upgrading interiors.

Key Factors Affecting Cost:

Scope of Works: Minor renovations are significantly cheaper than major structural changes.

Condition of the Existing Structure: Aging buildings might require costly reinforcements to support new additions.

Design and Finishes: High-end finishes or detailed carpentry work for interiors can increase costs.

Estimated Costs:
For minor works, costs can start as low as $150 psf. More extensive alterations involving structural changes can range from $200 to $400 psf.

  1. Additional Costs to Consider

Regardless of the type of project, several additional costs can arise:

Professional Fees: Fees for architects, engineers, and project managers typically range between 8% to 12% of the total construction cost.

Regulatory Costs: These include submission fees, surveyor reports, and inspections.

Temporary Housing: If you need to vacate your property during the works, temporary housing costs can add up.

Unforeseen Contingencies: Allocate about 10% to 15% of your budget for unexpected changes or delays.

Making the Right Choice

The choice between a new erection, reconstruction, or A&A works depends on your budget, goals, and the condition of your current property. While a new erection offers the most flexibility, reconstruction or A&A works can often achieve a similar outcome at a lower cost if planned well.
