extending your house from 2 storey to 2.5 storey means it would be a reconstruction project. Fee payable to URA is $6420 (including GST). you will need to find a QP (architect or professional engineer) to do the submission for you. as you've been staying in the house for so long, I supposed you have the original building plans. talk to a PE or a builder (who would find a PE) on whether it is possible to extend your house to 2.5 storey or not. A lot depends on the existing foundation and whether the foundation can support the additional storey. If foundation needs to be strengthened, then it would mean extra cost. Then the PE would need to design the structure for the new attic storey. Whether to use steel structure or RC structure for the attic would be up to the PE and costs would be different. Redo the wiring and sanitary would be another big cost especially if the existing pipes are all concealed. this would mean the existing pipes need to be hacked out from the walls and new conduits/pipes inserted and walls re-plastered. this could be easily 80k to 100k in costs without the sanitary fittings included. If your existing house does not have 3 phase electricity and you wish to upgrade to 3 phase, then need to pay another 5K plus to SP Group to run the new cable to your house. The electrician would also need to run new underground cables from the meter compartment to the distribution box in your house. All in all, expect to spend at least 300k and up to redo your house. Construction cost is evolving and may go upwards depending on how the COVID-19 situation pans out. Currently all construction workers need to undergo swab test every 2 weeks and this cost is being borne by the government until 31 Mar 2021. If there is no vaccine for COVID-19 by then and government decides not to fund this testing anymore, this cost would be borne by the contractors and passed back to the owners/developers. Assuming the cost of testing each worker every time is $200, if the contractor has 10 workers on hand, this would be an additional $4000 every month. So if your project is estimated to take 12 months to complete, this swabbing cost would most likely be passed back to you and your construction cost would increase by $48k. If you add in the cost recovered by other subcons, this additional cost would be much higher. While it is good your you to start planning the works now, I would suggest holding off the works for 1 year or so if you can until at least the COVID-19 situation stabalises in SG. Currently even though construction industry has restarted and BCA had allowed many projects which were paused during the CB to resume, I still see many landed housing projects not restarting due to the lack of workers.
