Yup, I understand abt the different power requirements. Planning to do POE for IP cameras as well so have to think which is better in terms on cost and management by using back same brand switch or something else.

For private residence built for own stay, can always get waiver for certain things from relevant authorities. If you doing the PV before getting CSC, maybe ask your architect to consult SCDF? If doing after then go by SAF rule 7 la.

depending on how much build up area you are looking at and materials used, could be somewhere near the region of 900K and upwards

sadly, I would need to do that as well for my new house construction.

I'm also planning to use Ubiquiti APs for my new house. Dunno if should also use Ubiquiti POE switches as well or not to power the APs and IP cameras.

Dunno why the moderator flagged me for soliciting. Anyway, the SCDF requirements is geared towards fire safety so I think private landed residential properties would need to comply with the requirements. If you are planning to do a PV array, you will need to provide access to the roof else how are the maintenance people going to access the panels?

how much built up area are you looking at? current average construction prices is about $300 psf and this excludes professional fees and submission fees. so if you are intending to have a built up area of > 3000sqf, you would be looking at a budget of 1M thereabouts.

2700sqf is quite a big land size. Semi-d? to rebuild, you definitely need an architect to sign off whether it's directly or through the builder

what is the coverage area of the PV panels for your house?

If you are doing a rebuild, then run the lan cables and buy enterprise grade WIFI access points. This will give a better performance compared to mesh networks. Depending on your house layout, you might be able to get away with using 2 APs (1 in attic and 1 in 2nd floor) to provide the coverage. If it's me, I would pull an additional 2 cables on 1st and 3rd floor just in case I need additional APs to provide the full coverage since you won't really know how good/bad the coverage is until you use it.

There's a couple of transactions at opera estate for 1400sqf units recently so I guess one of it is yours. 500k for a 3000sqf 2.5 storey rebuilt is unlikely to happen. A conservative amount would more likely be about 700k. If your house is abutting a back alley (at opera estate), then you would have saved on needing to protect the sewer as the sewer line for your house is most likely in the back alley.

Depends on how much build up area you want and materials used. If your house has a sewer running across, then will need to spend $ to protect the sewer else you can't built anything over the sewer. Average construction cost is about $300/sf not inclusive of professional fees and submission fees. If you want a home lift then add another few tens of k to the cost. Best is consult an architect first and buy the necessary plans so you can gauge your options. Btw, your purchase is in the east side?

you need to get hold of the structural plans for the existing house and get the PE to calculate whether the existing structure can take the load of the additional 1.5 storey. If you haven't bought the house, then the existing owners need to get the plans for you since the plans would not be available to any 3rd party without owner's authorization. anyway, I think chances of adding 1.5 storey on existing structure would be quite slim unless the existing columns can be reinforced to take up the additional load. if such major works to existing structure needs to be done, might as well go for a total rebuilt.

was the house rebuilt 30 years ago or major A&A done? like what yoongf mentioned, the cost depends a lot on the materials you choose and how much GFA you decide to have so 1M could be possible. let me know if you want an architect as I'm also in the process of doing a corner terrace rebuilt.

how old is the existing house? you will need to purchase the existing building plans and have a professional engineer to compute whether the existing structure is able to take the load of an additional storey or not. Since the PE might not be versed in the various planning requirements, you may need to engage an architect as well to do the necessary design and submissions. anyway, i think chances of you being able to add an additional storey is quite low. even if the existing structure can be reinforced to take the additional load, it might be better to just demolish and rebuilt as there's more flexibility in the design of your dream home rather than work around the constraints of the existing building structure.

check with your town council

not sure on this. check with everyone including your property agent and MCST as well.

the question is whether the roof belongs to you or is part of the common area/infrastructure of the entire development....

plans can be purchased from BCA. but it seems that not everyone can purchase the plans. as mentioned, best is consult an architect on whether there is still available GFA for you to build the loft or not and then consult a PE on whether the existing structural can take the load of the additional 40sqm of loft area. reinforcing the columns and beams in your unit may not be enough for the columns and beams in the lower units to support the extra load.

can share which seller you bought the tiles from taobao? the rooms facing the expressway would be quite noisy at night even with the windows closed. is yours the top floor unit? normally only top floor unit will have such thick beams.

you should have a good idea of what type of appliances you want to get so your ID/contractor would know how much space to leave out and what size to cut out. if you tell your contractor to cut out a 60cm hole in your countertop, you would not be able to use a 70cm or 80cm wide cooker. or if you cater only say 80cm width for fridge, you would not be able to buy a 2 door fridge which would be 90cm in width. same for height as well. do also understand that appliances don't last forever. so if you built a space just nice to fit in a fridge which you choose now, you may not find back a fridge of the exact same size in future if you need to replace the fridge.

plot ratio can be found on URA master plan. this is free information which is available online. Since you mentioned 4th floor is the top floor, I believe the plot ratio is 1.4 which is common in Katong area. do note that if the current development GFA is already maximized, you would not be able to add on the loft. Since you need to compute the total GFA after your addition, you may need to purchase the building plans to find out the current GFA for the building. also, structural plans need to be purchased to check if the building can take the weight of the additional loft or not. simply reinforcing the beams and columns in your unit would not work since the columns of the lower units may not be able to take the additional load. I would suggest you consult an architect on your plans as not all PE, contractor/builder may have the necessary knowledge to compute the existing GFA based on the building plans. anyway, if this is a more recent development, developers would have maximized the allowed GFA in the building design so you would not be able to build your loft.

perfectly normal. hinges normally open slightly more than 90 degrees. you can buy those small transparent semi-circular rubber bumps and stick on the wall or your cupboard doors to protect the doors. for the 2 side by side doors, just open them gently if you do not want to use the rubber stoppers. I used to have the rubber stoppers stuck to the wall to protect my fridge door handle as well.

depends on what type (sunken or above ground) you are looking for and the size. my friend is doing a sunken pool for her inter-terrace rebuilt at her car porch area and the pool is costing her about 35k. she mentioned she had gotten quotes as high as 80k for the pool.
