Hmm.. based on your lvl 1 floorplate of abt 2k sqft, your land plot shd be quite big.. ie this is quite an atas house. But... all your ceiling heights are unusually low, lower than HDB substantially. Are u sure you want to proceed with this design? Low ceiling heights feel much hotter, and for the attic floor which is your master rm, will require substantially bigger cooling power. Also rooms that gets the afternoon sun. For me.. i agar at 70btu per sqft to be able to get that instant freeze feeling.

URA envelope and attic guidelines require 1 end to be a 45 degree slope towards the spring line. If this area was designed as another roof terr, the usable space is maximised. The middle portion between the front and back roof terr might as well do a rc flat roof since the resultant area may be too small to justify getting a steel roof subcon in, in terms of shop drawings n mobilisation time. After CSC, add a steel ladder to access this upper roof terr. Can even put veggie farm up there.

17 x 175 = 2975mm. The lower level is abt 3m high floor to floor?

Are you doing RENO or A&A works?

There are many examples of odd shaped lots that were successfully sub divided. I believe the criteria is not so much the frontage width, but the physical building cannot be less than 6m wide. If somehow, u can reorientate the structure to have min 6m each, it can be accomodated.

It is possible to get thru with the sub division. But... It has to be a back to back semi D and the building layout is L shaped. The front unit is a 10m wide unit, and the rear semi D is accessed by a 5m wide long driveway. However, the front unit will hv a tiny footprint of 6m wide x 12-15m depth.

Home shelter has been a requirement since at least 18years already. Are u building a basement or are u thinking abt a small basement solely for the HS shelter?

TS, what u have mentioned is totally out of the norm. U mentioned that builder is still quoting you. U mention that PE submited to BCA. The usual practice is that design must be finalised first, then get authority approvals, then get builder quote. Is this sequence you are following? Which step are you now?

There is no GFA limit for landed properties, which is limited by the envelope boundaries. However, the original developer that sub divided the area into multiple plots have to pay Development Charges to enhance the land from the original baseline GFA to the proposed GFA. DC rates are typically half the market land psf, not a small sum. As such, the original developer will not attempt to build to the max envelope, since the selling price for landed is typically based on land psf.

The text on the drawing suggest that the architect was trying to comply with attic guideline which says... An attic is an incidental space that may be allowed within the permissible two-storey and three-storey envelopes respectively. Where roof terraces are proposed on attic roofs, they shall be located at least 3m below the top extent of the permissible building envelope to ensure future coverings by homeowners remain within the overall building envelope. Roofs with less than 3m below the top extent of the permissible building envelope shall be proposed as RC flat roofs that are non-accessible except for maintenance purposes

Is bedroom 4 on level 3? Corner terr and semi d.. 3rd floor need setback 3m. I suspect is this reason.

Aircons, storage heaters maybe due for replacement. Solar water heater is worth installing.

I chopped down a few 6m tall trees myself. Took me 2 month worth of weekends and was extremely fulfilling. Used cordless drill instead of saw. Now i really appreciate NParks tree management policies. U will need very understanding family members though.

The QP has to declare that the fittings are compliant, not so much abt physical inspection. If u really want to use exotic stuff, TOP with HDB type fittings then after CSC, arrange to swap.

Is best to have a seperate pedestrian gate if space allows. Open close for every human traffic is heavy wear and tear on the mechanism. The weight of the gate is increased by extra framing. If the human gate is accidently left open when bifold gate is activated, there will be a very interesting conversation in the household. Anyway if power failure, the mechanism have a manual bypass key to allow manual operation of gate.
