When calculating the cost of a home renovation, here are some of the things you need to take note of: Property size. Obviously, the larger the home, the more labour and materials are needed to complete the renovation. It explains why condominiums and landed properties could cost significantly more than HDB flats. Property status. Generally, resale properties cost more to renovate because most of them come with built-in furniture and appliances that need to be dismantled. Extent of work required. It needs no explaining that the cost of renovation will be a lot pricier if more work needs to be done. Some services that can add a hefty amount are painting, demolition, carpentry, masonry, and disposal. Type of materials needed. If you don’t pay attention to the materials suggested by your contractor, you’re definitely going to end up paying more than you should. Always take note of the flooring material and type of countertop. For example, granite and marble may be nice to look at, but these materials can hike up the total bill significantly.
