Up to 30% off across categories — locked in as soon as 10 households from Sun Plaza Spring indicate interest in the group buy. The exact discount depends on the brand: up to 30% off KDK ceiling fans (the deepest tier), 10–25% off Aqara smart home, and 10% off across most other ceiling fans, power tracks, and BTO lighting. Headline rates are all-in for the estate group-buy — PayNow 4% and Bulk 3% are already factored in, not stacked on top.

What we know about Sun Plaza Spring
Project background: Sun Plaza Spring is an HDB BTO project at Tampines Street 41 / Tampines Street 42 (Tampines, District 18), launched in the August 2022 BTO sales exercise. The development collects keys on a rolling basis across the estate.
Where it sits. 3 residential blocks (11 storeys), 267 units of 4-room (150) and 5-room (117) flats. Bounded by Tampines Street 41 and Tampines Street 42, with the development named after the nearby Sun Plaza Park. Central green space, children’s playgrounds, fitness stations, a roof garden above the multi-storey carpark, and an on-site childcare centre.
Electrical provisions (standard HDB BTO): No neutral wire at any light-switch point. Water heater + instant heater switches typically have neutral. 230V / 50Hz across the unit. Backbox size is the standard Singapore 86mm — every Aqara H1 EU, SmartGeez M8 Pro and Yeelight Pro switch in our range fits without modification. We recommend pulling neutral wires to your light switch points during the renovation phase — it unlocks the more stable neutral-version smart switches and is the cheapest moment to do it.
What HDB actually provides — and what you’ll need to add. This is the most common surprise for first-time BTO buyers: HDB BTO units (and most condos) ship with traditional wall switches only — no light fittings, no ceiling lights, no downlights, no fan hooks. Every light fitting, every ceiling fan, and every fan hook in your unit is something you specify and your electrician installs during renovation. That’s why most Sun Plaza Spring households spec a full BTO lighting bundle (ceiling lights, bulbs, downlights, drivers, smart switches) during the renovation phase — the savings vs piecing it together over time are significant, and the labour is most efficient when the electrician is already on site.
Connectivity: all our smart-home brands work on the standard SG Wi-Fi + Zigbee / Thread / Matter stack. No special infrastructure required at key collection.

Frequently asked questions — Sun Plaza Spring
When should I lock in my Sun Plaza Spring group-buy order?
Ideally 6–8 weeks before your expected key collection date. That gives us time to coordinate delivery with your electrician’s schedule and ensures stock on the specific fan, switch and BTO lighting SKUs you want.
Do I need to pay a deposit to reserve group-buy pricing?
No. Pricing is locked when your household confirms the quote in writing on WhatsApp. Each household pays individually when you’re ready — our team will walk you through the payment options at quote time. We do not pool payments or share carts.
Can I add Aqara cameras, sensors and locks to my group-buy quote?
Yes. Any Aqara SKU can be quoted at the estate-exclusive Aqara rate — including hubs (M3, M2, E1), cameras (G3, G5 Pro, G100), sensors (FP2, motion, door/window, leak, T&H), and smart locks (U200, U300, U100, A100 Pro). Message us with your full wishlist.
What if my renovation schedule shifts?
Group-buy pricing holds for 90 days from quote confirmation. If your move-in or renovation schedule shifts past that, we re-quote at current rates — but we’ve never run a rate below a prior group-buy rate, so customers are typically fine.
Is installation included?
No — PassionHome ships products, your main contractor or electrician installs. The exception is selected Aqara smart locks (U100, A100, D100, D200i) which include installation. App setup is DIY-recommended; paid setup is available on request.
Do I get the same warranty as a non-group-buy order?
Yes. Group-buy orders carry the same local warranty as any PassionHome.sg order — Aqara up to 24 months at the SG Official Service Centre; Yeelight Pro at 36 months; ceiling fans vary by brand. No difference by channel.
