The cost of interior design for landed properties varies greatly depending on several criteria, including the materials used, the complexity of the design, the project’s scale, and the interior designer’s reputation. Homeowners should really prepare for a wide price range as landed homes need more customisation than HDB apartments or condominiums.
Discover a breakdown of the key cost factors and estimated price ranges for landed interior design in Singapore, helping you plan your budget effectively.
Cost Factors Affecting Landed Interior Design
1. Property Size and Layout
Larger homes with multiple floors naturally require more materials, labour, and design expertise. A typical terrace house will have a lower interior design cost than a bungalow due to the difference in square footage. Complex layouts with split levels or odd-shaped spaces may also increase design fees as more customisation is required.
2. Scope of Renovation
The extent of the renovation heavily influences the cost. A basic makeover with new furnishings and minor touch-ups costs significantly less than a full-scale renovation that includes structural changes, custom carpentry, and luxury finishes. A full landed property interior design project, including demolition, rebuilding, and extensive customisation, will be the most expensive.
3. Design Style and Customisation
Luxury or highly customised designs require premium materials and skilled craftsmanship, increasing costs. Costs will be lower if a homeowner prefers a minimalist or modern look with off-the-shelf furniture. However, intricate design styles such as classical European, Peranakan, or industrial chic require more bespoke elements, leading to higher expenses.
4. Material Selection
Material choice is a major cost driver in landed interior design. Imported marble, high-quality timber, and customised metal or glass elements will significantly increase the budget. On the other hand, opting for locally sourced or engineered materials can help control costs while maintaining aesthetics.
5. Interior Designer’s Fees
Hiring experienced interior designers typically comes at a premium. Their fees can be structured as a flat fee, a percentage of the total renovation cost, or an hourly consultation charge. Established firms with a strong portfolio often charge higher rates, while freelance designers or smaller firms may offer more competitive pricing.
6. Structural and M&E Works
Many landed homes require structural alterations such as knocking down walls, extending spaces, or reinforcing load-bearing structures, which adds to the overall cost. Additionally, modifications to mechanical and electrical (M&E) systems, including rewiring, plumbing upgrades, and air-conditioning installation, contribute to expenses.
7. Smart Home and Technology Integration
Modern landed property interior design often incorporates smart home features such as automated lighting, security systems, and climate control. These technologies enhance convenience but add to the renovation budget, especially when integrating high-end automation systems.
Estimated Cost Ranges for Landed Interior Design
Basic Renovation (SGD 50,000 – SGD 150,000)
A basic renovation typically involves repainting, minor carpentry works, new flooring, and furniture replacement. This cost range applies to homeowners who want a refresh without major structural modifications.
Mid-Range Renovation (SGD 150,000 – SGD 350,000)
This budget allows for custom carpentry, high-quality flooring, and premium furnishings. It may include minor structural changes, bathroom and kitchen upgrades, and built-in storage solutions. Mid-range landed interior design projects balance aesthetics and functionality while keeping costs reasonable.
Luxury and Full-Scale Renovation (SGD 350,000 – SGD 1,000,000+)
Expect to pay upwards of SGD 350,000 for high-end interior design, especially for large landed properties such as semi-detached houses and bungalows. This budget covers extensive customisation, premium materials, smart home automation, structural alterations, and high-end furnishings. Some luxury renovations exceed SGD 1 million, particularly if the project includes major rebuilding works.
How to Manage Landed Interior Design Costs
1. Set a Realistic Budget
Homeowners should establish a clear budget before engaging with interior designers in Singapore. Understanding what is essential versus optional helps prevent overspending.
2. Compare Quotes from Multiple Designers
Different interior designers charge varying fees based on experience, portfolio, and service scope. Comparing multiple quotes ensures that you get value for money.
3. Prioritise Key Areas
Focus on renovating key spaces, such as the living room, kitchen, and bedrooms, to manage costs. Secondary areas like guest rooms or outdoor spaces can be updated later if necessary.
4. Choose Cost-Effective Materials
Opting for high-quality but cost-effective alternatives, such as quartz instead of natural marble or engineered wood over solid timber, can significantly reduce expenses without compromising aesthetics.
5. Plan for Contingencies
Renovation projects often encounter unexpected costs, such as structural issues or last-minute design changes. Allocating at least 10-20% of the total budget for contingencies helps avoid financial strain.
Conclusion
The cost of landed property interior design in Singapore varies widely based on factors such as property size, design complexity, material choices, and designer fees. High-end projects can cost more than SGD 1 million, particularly for extensive makeovers, while basic restorations might start at SGD 50,000. Homeowners should collaborate closely with respectable interior designers to maximise their funds and attain the intended result while guaranteeing long-term value. Remember, effective cost management can be achieved by careful planning, material selection, and prioritisation of critical areas.
