Design brief

Nhiệm vụ thiết kế

Two-storey family townhouse with roof terrace and altar penthouse (tum) on a 10 m × 15 m urban lot in Vietnam. Reinforced-concrete frame with brick infill, built to both side boundaries.

Programme (assumption to confirm)

2 storeys + roof terrace with altar penthouse; 5 bedrooms (one flexible study), 3 bathrooms, garage for one car.

2 stairs (ST-01 GF→L1, ST-02 L1→RF) share one core of 4080 × 2100 mm, each a U-shaped (dog-leg) return stair. The side walls are party walls on the boundaries, so daylight comes from the front, the rear, the recessed loggia and the skylight (SK-01) over the stair; 3 service shafts (SH-1, SH-2, SH-3) carry the soil stacks, grey-water stacks, vents and exhaust ducts.

Site and orientation

Khu đất và hướng nhà

Location not confirmed

Ho Chi Minh City (placeholder until the lot is confirmed). Climate, sun and the local planning rules must be re-checked once the actual lot is known.

Location · Vị trí: Ho Chi Minh City (placeholder until the lot is confirmed) — 10.78° N, 106.70° E, UTC+7
Lot · Lô đất: 10.0 m frontage × 15.0 m depth = 150 m²
Building envelope · Khối nhà: x 0–10000, y 1150–13000 mm (10000 × 11850 mm, outer faces)
Setbacks · Khoảng lùi: front 1.15 m · rear 2.00 m · left 0.00 m · right 0.00 m (party walls on both sides)
Street · Đường: Street (assumed 8 m road + 3 m sidewalk)
Levels outside · Cao độ ngoài nhà: sidewalk −0.300; ground floor 300 mm above the sidewalk (≥ 150)
driveway · dốc xe: ramps from −0.300 at the street side to −0.150 (13.0 %), 4.07 m²
front yard (pedestrian) · sân trước (lối đi bộ): level at −0.150, 7.18 m² — a 150 mm step up from the sidewalk at the boundary
rear yard · sân sau: level at −0.150, 18.48 m²
Entrance step · Bậc tam cấp: −0.150 → ±0.000 (150 mm riser) on the front yard (pedestrian)
Gates · Cổng: SE-gate-car Car gate (6-leaf folding, 3 + 3) 3.5 m: 6 leaves of 585 mm, folding, opening into the lot (never over the sidewalk); leaf bottom −0.190 clears the driveway under the sweep by 21 mm; lever latch that opens from inside without a key (no padlock on the escape route); flexible brush seal along the leaf bottoms; manual release if it is ever motorised.Cổng xe 6 cánh xếp (3 + 3) 3,5 m: 6 cánh, cửa xếp (gấp), mở vào trong khuôn viên; mép dưới cánh −0.190, cách mặt dốc xe 21 mm.
SE-gate-ped Pedestrian gate (2-leaf) 1.0 m: 2 leaves of 500 mm, double swing, opening into the lot (never over the sidewalk); leaf bottom −0.130 clears the front yard (pedestrian) under the sweep by 20 mm; lever latch that opens from inside without a key (no padlock on the escape route); flexible brush seal along the leaf bottoms.Cổng phụ 2 cánh 1,0 m: 2 cánh, mở quay 2 cánh, mở vào trong khuôn viên; mép dưới cánh −0.130, cách mặt sân trước (lối đi bộ) 20 mm.
Fence and boundary walls · Hàng rào, tường rào: Front fence and gates +1.500, 1.80 m above the sidewalkUnder review — conflicts with research: Front fence and gates higher than an open 1.2 m fence
Front-yard side walls: SE-bwall-fl +1.500, 1.65–1.80 m above the driveway; SE-bwall-fr +1.500, 1.65 m above the front yard (pedestrian)
Rear-yard walls: SE-bwall-rl, SE-bwall-rr and SE-bwall-rear +2.300, 2.45 m above the rear yardUnder review — conflicts with research: Solid boundary walls between the lots
Facing · Hướng nhà: South-East · Đông Nam (front façade bearing 135°)
True north · Hướng Bắc thật: 45° clockwise from plan “up” (+y, into the lot)
Neighbours · Nhà bên: Neighbour (assumed 3 storeys), 10.5 m above the sidewalk (top +10.200); Neighbour (assumed 2 storeys), 7.5 m above the sidewalk (top +7.200)

Plan origin (0, 0) is the front-left corner of the lot seen from the street; +x runs along the street, +y into the lot, and every plan on this site is drawn with the street at the bottom. Elevations are relative to ±0.000 = ground-floor finished floor level. The ground floor must sit at least 150 mm above the sidewalk [TCVN 9411:2012 6.4.1.1]; the driveway ramps up inside the lot, never on the sidewalk [TCVN 9411:2012 6.4.7.2]; gate leaves never open beyond the boundary [TCVN 9411:2012 6.4.6.2].

Assumptions

AS-05	Setbacks	Front setback 1.15 m, rear setback 2 m (≥ 2.0 m so the rear façade may have ordinary windows, TCVN 9411 6.4.3.1), built to both side boundaries.	Footprint and building density. Check the lot’s planning information (chỉ giới xây dựng).	To be confirmed · Cần xác nhận
AS-06	Program	2 storeys + roof terrace with altar penthouse; 5 bedrooms (one flexible study), 3 bathrooms, garage for one car.	Whole layout.	To be confirmed · Cần xác nhận
AS-07	Structure	RC frame, 220×220 columns, ground beams on pile caps or pad footings — to be designed by a structural engineer after a soil survey. Footings on the boundaries are eccentric (they may not cross the lot line); the septic tank, the underground water tank and the inspection pits sit between ground beams, clear of the column footings, and are designed together with them.	Column/beam sizes, foundation drawings, final tank positions.	To be confirmed · Cần xác nhận
AS-08	Neighbours	Neighbours are built to the boundary; no windows are possible in side walls.	Daylight strategy (front, rear, skylight).	To be confirmed · Cần xác nhận
AS-09	Ground-floor height	Ground floor 4.1 m floor-to-floor so the clear height to the slab soffit is ≥ 3.6 m everywhere, including under the sunken first-floor bathrooms (TCVN 9411 5.5.6). False ceilings in the habitable rooms sit at 3.2–3.3 m below the beams (WC 2.7 m).	If the authority measures clear height to the finished ceiling, the false ceilings must rise or be omitted in the main rooms.	To be confirmed · Cần xác nhận
AS-10	Density rule	Maximum density 80 % for a 150 m² lot by interpolating QCVN 01:2021/BXD Table 2.8 (interpolation is explicitly allowed there). QCVN 01:2026/BXD takes effect on 01/01/2027 with the same values, but its interpolation note is printed under a different table; the HCMC local table (QĐ 56/2021 Annex 18) is reported by secondary sources only and is unverified.	If the ward applies no interpolation from 2027, the allowed footprint could be smaller — confirm before the permit.	To be confirmed · Cần xác nhận
AS-11	Front fence and boundary walls	Light open fence and gates 1.8 m above the sidewalk with light security screening (TCVN 9411 6.4.6.1 d). The default for a façade < 2.4 m from the red line is an open fence ≤ 1.2 m. The side and rear boundary walls are solid masonry for privacy and security (front-yard returns at the fence height, rear yard 2.3 m), while TCVN 9411 6.4.6.1 e prefers fences between houses that are open above a ≤ 0.6 m solid base and as high as the front fence.	The ward may require the lower 1.2 m open fence and open boundary fences agreed with the neighbours.	To be confirmed · Cần xác nhận
AS-12	Household size	Up to 8 people (grandparents, parents, children, guests) for water, septic and parking sizing.	Tank and septic sizes, number of bedrooms.	To be confirmed · Cần xác nhận

Levels

Cao độ các tầng

Southern Vietnamese names (Tầng trệt, Lầu 1, Sân thượng & tum, Mái tum) are used on the drawings; builders from the north say Tầng 1 (Tầng trệt), Tầng 2 (Lầu 1). The penthouse (tum) is not counted as a storey. Elevations are finished floor levels; the structure sits below them by the floor build-up (see the slabs below).

Wall types

Các loại tường

Every wall is modelled as one of these compound types; the layer thicknesses add up to the nominal thickness and are drawn to the same scale. Southern “tường 100 / 200” labels are only nominal, so the drawings state the build-up explicitly. Brick is the southern gạch ống 80 × 80 × 180 [TCVN 1450:2009]. Download wall-types.csv

Walls start on the structure, below the floor finish of their level (base offset GF −200/−150/−50, L1 −50, RF −130, TR −170 mm), and run to the underside of the slab above; parapets stop at their stated height above the finished floor.

Layers from the top of the finish down; the level line (FFL) is the top of the finish. Concrete class B20 corresponds to mác 250 [Thông tư 38/2026/TT-BXD (Phụ lục VII)]; reinforced concrete must be at least B15 [TCVN 5574:2018 6.1.1.6]. Download slab-types.csv

Waterproofing membranes have no thickness of their own (FL-GF-WC, FL-WC-450, FL-OUT-170, RF-250, TR-290); they are drawn as a dashed line between the layers they separate.

Room schedule

Bảng thống kê phòng

Areas are clear (net) areas to the finished inside faces of the walls. Rooms open to the sky are counted separately from the indoor area. Finish codes refer to the finishes table below. Width and depth are the overall dimensions; 6 rooms (0.05, 0.07, 0.08, 1.06, 1.10, 1.12) are cut around a service shaft, so their area is less than width × depth.

Structure

Kết cấu

Reinforced-concrete frame (khung BTCT) with brick infill walls, columns on the grid intersections and beams on the grid lines. All sizes below are preliminary placeholders for the architectural model.

Preliminary — to be designed by a licensed structural engineer

Column and beam sizes, reinforcement and the foundation must be calculated by a licensed structural engineer after a soil survey. Nothing in this section is a structural design.

Concrete · Bê tông: B20 (M250) in the slab types; at least B15 for any RC member [TCVN 5574:2018 6.1.1.6]; B20 ≈ mác 250, B25 ≈ mác 350 [Thông tư 38/2026/TT-BXD (Phụ lục VII)]
Reinforcement · Cốt thép: ribbed bars CB300-V or CB400-V, plain links CB240-T [TCVN 1651-1:2018 · TCVN 1651-2:2018]; design strengths Rs 260 / 350 / 210 MPa [TCVN 5574:2018 Table 13]
Concrete cover · Lớp bảo vệ: main bars ≥ 20 mm indoors (≥ 25 mm above 75 % humidity), ≥ 30 mm outdoors, ≥ 40 mm in the ground or foundations on blinding [TCVN 5574:2018 10.3.1.2]
Columns · Cột: C1 220×220 (220 × 220), 45 column elements (one per storey: GF→L1 18, L1→RF 18, RF→TR 9) on the grid crossings (grids A, B, C, D, 1, 1a, 2, 3, 4). Each starts on the lowest beam top at its base: GF −150 (A/1 and B/1 −200 on GB-1/A-B), L1 −50 (B/1, C/1 and D/1 −100 on B-L1-1/B-C and B-L1-1/C-D), RF −130 mm from the level FFL. Contractor guides treat 220 × 220 as standard for 2-storey houses with 4–5 m spans and suggest 250 × 250 for 5–6 m; the largest grid span here is 3.79 m [Townhouse structure practice]
Beams · Dầm: depth ≈ span / 12 (min 300) including the slab, width 220 to sit in the walls; each beam’s top is the lowest RC top of the slabs it carries: L1 −50 (B-L1-1/B-C, B-L1-1/C-D and B-L1-C/1-2a at −100, under a lowered slab), RF −130, TR −170 mm from the level FFL; the beams across grid 1a are split at the A/1a and B/1a columns (GB-A/1-1a, GB-A/1a-2, B-L1-A/1-1a, B-L1-A/1a-2, B-RF-A/1-1a, B-RF-A/1a-2, GB-B/1-1a, GB-B/1a-2, B-L1-B/1-1a, B-L1-B/1a-2, B-RF-B/1-1a and B-RF-B/1a-2); transfer beam B-RF-C/1-2 (220 × 600) carries column C/1a mid-span (the only column that starts on a beam); beams with a stated purpose: B-L1-2/C-D, B-L1-3/C-D, B-L1-4/B-C, B-L1-B/3-4, B-L1-C/2-3 and B-L1-C/3-4 500 deep — frames a sunken bathroom slab (drop 300); B-L1-C/1-2a 500 deep — loggia part of the grid-C beam 1–2 (continuous with B-L1-C/1-2b); its top follows the lowered loggia slab; B-L1-C/1-2b 500 deep — continuous with B-L1-C/1-2a; carries secondary beam BS-L1-01 and wall L1-C-FRONT; BS-L1-04 500 deep — frames the sunken master-bathroom slab on its face (clear of SH-1) and carries the 110 partition; BS-L1-03 500 deep — carries the 110 partition and frames the sunken shared-bathroom slab; BS-L1-01 350 deep — carries recessed L1 front wall behind loggia; BS-RF-01 350 deep — carries the tum front wall; columns A/1a and B/1a below, C/1a on transfer beam B-RF-C/1-2; BS-L1-02 and BS-RF-02 300 deep — stair opening edge beam. Preliminary rules h = L/10–L/15 (main) and L/15–L/20 (secondary) [Townhouse structure practice]
Ground beams · Dầm móng (giằng móng): 220 × 400, 220 × 600 on all grids, top at −0.150 (GB-1/A-B −0.200, under a lowered slab so the floor build-up passes over it); practice h = L/10–L/8, width at least the wall above [Townhouse structure practice]
Foundation · Móng: to be chosen after 2–3 boreholes. In HCMC soft soils small houses under 3 storeys commonly use anchor-jacked precast piles (≈ 40–45 t per pile head); pad or strip footings only where firm soil is shallow. Piling can crack neighbouring walls — plan protection with both neighbours [Townhouse structure practice]. Jacked piles are accepted per [TCVN 9394:2012]. Foundations and pipes stay inside the lot [TCVN 9411:2012 6.4.5.2].
Party walls · Tường biên: the side walls are private walls wholly inside the lot (outer face on the boundary), so nothing crosses onto the neighbours [TCVN 9411:2012 4.6]
Infill · Tường chèn: infill walls tied to the columns and beams; frame infill ≤ 220 mm may be hollow brick, parapets above the roof in solid brick [TCVN 4085:2025 6.3.3.4–6.3.3.5]

Services (MEP)

Hệ thống kỹ thuật: cấp thoát nước, điện

Outline of the building services for the architect, the MEP engineer and the builders. Positions and routes come from the model (every drain names what it discharges into); sizes marked ≈ must be confirmed by the MEP engineer. Roof drainage is drawn on sheet A-105 (KT-06) roof plan — drainage and falls.

Water supply · Cấp nước

City main → Water meter (on the front boundary) → Underground water tank ≈ 1.9 m³ net (under the living room floor (0.02)) → Transfer pump (float switch) in a weatherproof box (in the front yard (pedestrian)) → 1 500 L rooftop tank on the penthouse roof → gravity to the fixtures. Every row house needs an underground tank for daily use and fire water [TCVN 9411:2012 7.1.4]; connect to the public main [TCVN 9411:2012 7.1.5].Nước máy → Đồng hồ nước (tại ranh đất phía trước) → Bể nước ngầm ≈ 1,9 m³ (thể tích hữu ích) (dưới sàn phòng khách (0.02)) → Máy bơm (phao tự động) trong hộp che (ở sân trước (lối đi bộ)) → bồn nước trên mái tum → cấp tự chảy xuống các thiết bị.
Demand: 8 people × 150–180 L/day (Type I city rate) ≈ 1.20–1.44 m³/day [TCVN 9411:2012 7.1.2]; the 1 500 L roof tank holds about 1.1 day.
SV-water-ug: envelope 2400 × 1200 × 1 400 mm = 4.03 m³; inside 2.08 m³, net ≈ 1.89 m³ with 150 mm RC walls, base and lid and 100 mm freeboard — about 1.4 days at the demand; 1 sealed access hatch 600 × 600 mm in the floor above; 3.50 m from the septic tank. Buried drain runs keep clear of it Pass: Buried drain runs keep clear of the drinking-water tank and the boundary footings.Bể nước ngầm ≈ 1,9 m³ (thể tích hữu ích): thể tích bao 4,03 m³, thể tích hữu ích ≈ 1,89 m³; 1 nắp thăm kín trên sàn.
Static head from the tank base (+12.200) to the floors with fixtures: GF 12.2 m ≈ 1.20 bar; L1 8.1 m ≈ 0.79 bar; RF 4.7 m ≈ 0.46 bar — before pipe losses. HCMC contractor packages add a booster pump (máy bơm tăng áp) to the transfer pump [MEP practice].
A full 1 500 L tank weighs ≈ 1.5 t — the penthouse roof slab and beams must be designed for it on its stand Under review — to be confirmed.

Hot water · Nước nóng

Solar water heater 180 L on the penthouse roof (sizing not checked; confirm with the supplier and the MEP engineer).
Roof equipment stays inside the lot and should limit its visual impact on the street [TCVN 9411:2012 6.4.8.2] [QĐ 56/2021/QĐ-UBND (TP.HCM) (partly unverified)]. A rooftop PV system would be notified to the ward ≥ 10 working days ahead [QCVN 04-3:2026/BXD · ND 58/2025 (amended by ND 243/2026)].

Drainage & septic tank · Thoát nước thải, bể tự hoại

Septic tank, 3-compartment (≈ 2.0 m³ liquid) under the garage floor (0.01), −1.950 to −0.300; envelope 4.75 m³, inside ≈ 2.55 m³; outflow → SV-mh-2 → public drain, buried run 2.35 m along its drawn route; 2 access covers 500 × 500 mm. Under the garage between the ground beams, close to the A/1a and B/1a footings: the structural engineer designs the tank walls and base together with those pile caps (no excavation below a footing inside a 45° line from its edge). RC lid designed for car wheel loads, two heavy-duty (B125) sealed 500 × 500 covers between the wheel tracks of the parked car; vent to the roof via SH-1. Outflow Ø110 straight forward to the front pit (sleeve through the garage-door ground beam). Envelope 2.4 × 1.2 × 1.65 m (≈ 4.75 m³); 150 mm RC walls, base and lid and 300 mm freeboard → ≈ 2.0 m³ liquid volume. Fill-test watertightness for 24 h before backfilling. Size to be confirmed by the MEP engineer (≈ 8 people). Buried and covered [TCVN 9411:2012 7.2.4], watertight [TCVN 13967:2024 7.2.5]. Classic split: compartment 1 = ½, compartments 2 and 3 = ¼ each [MEP practice] Under review — to be confirmed.
Black water: the WC pans drain into the soil stacks — SH-1 Ø110 (0.05, 1.06) → SV-septic; SH-2 Ø110 (1.10) → SV-septic; vents Ø75 rise in the same shafts to the roofNước đen: bồn cầu → ống thoát phân SH-1 Ø110 → SV-septic; SH-2 Ø110 → SV-septic; ống thông hơi lên mái.

SV-trench trench drain in the driveway, grating at −0.264, bottom −0.480 → SV-mh-2 → public drain. Grating flush with the ramp (≈ −0.264); catches the driveway so no surface water runs onto the sidewalk.
SV-trench-2 trench drain in the front yard (pedestrian), grating at −0.160, bottom −0.400 → SV-mh-2 → public drain. The level yard falls 1 % to it; piped to the front pit.
SV-mh-2 inspection pit in the driveway, cover laid to the slope −0.254 → −0.176, bottom −1.000 → public drain. All waste and rainwater leave the lot here: septic-tank outflow, grey water and rainwater (separate pipes into the pit, one outfall to the public sewer/drain per local utility rules). In the driveway in front of the garage: sealed heavy-duty (B125) cover laid to the ramp (−0.254 → −0.176).
SV-mh-1 inspection pit in the rear yard, cover at −0.150, bottom −0.600 → SV-mh-2 → public drain. Collects the rear downpipes, the shared-bathroom grey water and the laundry waste. Main to the front pit: uPVC Ø110 at ≥ 1 % (≈ 1.9 %) along the rear yard to x ≈ 5.0 m, then forward under the GF slab between the septic tank and the water tank (≥ 1.7 m from each) and across the front yard; sleeves through the ground beams on grids 4, 3, 2 and 1.
Wet-room floors fall ≥ 2 % to the drain [TCVN 13967:2024 5.13]; waterproofing turned up ≥ 20 cm [TCVN 5718:1993 3.1.3] .
