Can you provide the rule of thumb for each cost item—construction cost, land financing cost, professional cost, and marketing cost—for a freehold site in Bukit Timah?

# Cost Component Rules of Thumb for Singapore Property Development

Based on Singapore property development practices, here are the typical rules of thumb for each major cost component:

Construction Costs

Construction costs in Singapore are among the highest in Southeast Asia, averaging approximately SGD $3,977 per square meter. This represents the single largest expense in any development project and covers all building materials, labor, site management, and structural work throughout the construction period.

Land Costs

Land costs vary significantly depending on location, tenure (freehold vs leasehold), and zoning. For freehold sites in prime areas like Bukit Timah, land costs are substantially higher than in other regions. The land cost typically represents 20-40% of the total project cost, depending on the location's desirability and scarcity.

Land Financing Costs

Financing costs are calculated based on the loan amount taken for land acquisition and the prevailing interest rates. These costs accumulate from the time of land purchase until the project reaches completion or break-even point. Generally, financing costs can add 5-10% to the total project cost, though this varies with market interest rates and the project timeline.

Professional Fees

Professional costs including architects, engineers, consultants, and legal advisors typically account for 2-4% of total project costs. This covers design work, regulatory approvals, structural engineering, and professional consultancy services.

Marketing and Sales Costs

Marketing and sales expenses usually range from 3-5% of total project value. This includes advertising, sales commissions for agents, branding, promotional activities, and other sales-related expenses.
