Practical Tips to Save Money While Designing 4-Room HDBs

You do not have to be super extravagant to revamp your 4-room HDB BTO flat. The proper selections, besides an analytical process, may have you attaining both a fashionable and practical home at an extremely low cost. Here are some tips that can assist you:

Focus on the Essentials First

As the most important areas are kitchens and bathrooms, which require more quality and endurance, invest more in those areas. Investing in bathrooms and kitchens ensures they are durable and functional, for these areas sometimes require more detailed installations.

Economical Materials

Choose materials for your project that balance cost with design. Examples include:

  • Flooring: Compared to parquet at S$18–S$30 per square foot, vinyl flooring at S$6–S$8 per square foot is a less expensive alternative to hardwood.
  • Countertops: Quartz countertops are more durable compared to other, more expensive materials such as granite or marble.

DIY Smaller Jobs

Do minor works yourself to save on costs, such as:

  • Painting: Save up to S$1,500 by painting the walls yourself with some tools and high-quality paints. 
  • Furniture Assembly: Assemble furniture that comes in flat packs rather than paying more for assembly.

These projects reduce costs while adding a personal touch to your home.

Make a Bundled Package Request

Many contractors, like Swiss Interior and Renozone, offer package deals that include several renovation services at a lower overall cost. These packages often include must-haves like painting, carpentry, and flooring to help you save time and money. 

Compare Quotes

To get the best price-quality ratio, ask several interior design firms to provide quotations. Check those that give comprehensive quotations and which may be open to negotiating their prices to your satisfaction.

These tips can help you stretch your budget and have a beautifully renovated home that fits your needs. Remember, the key to keeping the costs low is planning early and making smart decisions along the way.
