Under the 5-year Master Plan, the site is intended for a predominantly office development with a site area of 15,000 sqm and plot ratio of 4. Eco Realty plans to sell the asset after ramping up the occupancy and holding it for a period of 24 months upon completion of the construction. The capitalised rate is work out to be 5% at the time of the sale. The project team advises that the all-in construction cost is forecasted to be $ 3,200 psm on Gross Floor Area (GFA). Basing on the design, the net lettable area (NL) is 90% of the GFA. The schedule for design and construction stage is 4 months and 24 months respectively. The estimated net rent at the time of completion of comparable commercial office building is $100 psm per month. Eco Realty has also managed to secure a short-term loan at an interest rate of 6%p.a.
