Underneath Singapore's public housing blocks, the open ground-floor spaces known as void decks have long been the backdrop for weddings, funerals and late-night supper runs. But a handful of heartland blocks have turned these shaded concrete spaces into destinations in their own right — and they won't cost you a cent.

Start in Yishun, where Block 436 on Yishun Avenue 11 houses a 24-hour community library run entirely on a take-one, leave-one policy. Stock comes from resident donations, so the shelves rotate constantly, ranging from kids' books to biographies. Over in Jurong East, Block 224 on Street 21 has installed smart lighting panels that respond to how the furniture is arranged — shift the tables into a study setup or a dinner spot and the neon pink glow adjusts with you.

Art lovers can skip gallery admission fees at Blocks 55 and 56 on Pipit Road near Macpherson MRT, where walls splashed in Van Gogh's signature blues and yellows carry reproductions of Starry Night and his self-portraits, complete with explanatory blurbs. Bishan's Green Hub at Block 112, Bishan Street 12 packs even more in: a garden of eggplants and succulents, a community fridge stocked with donated fruit and snacks, a "Hall of Fame" of old typewriters and posters, and a small library with a swing seat. Tampines runs a similar idea at Block 441 on Street 43, with separate halal and non-halal fridges, baskets of donated vegetables, and shelves of pre-loved shoes and CDs.

Hungry at midnight? The Chef-in-Box Vendcafe at Block 320C, Anchorvale Drive in Sengkang is a 24-hour vending machine serving hot halal meals — think mutton rendang with biryani or Thai basil chicken with green curry fried rice — plus snacks and drinks, taking both cash and contactless payment. For something more social, descend into the basement of Block 450 Hougang Avenue 10, where a former bomb shelter now houses Dueller's Point, a Magic: The Gathering shop with a free-play area, board game tables and old-school drinks and snacks.

Newer estates are getting in on the act too. Block 107 on Bidadari Park Drive looks more like a condo lobby than a void deck, with minimalist finishes and pillars wrapped in vertical gardens. And transport nerds should keep an eye out for a quirky 2022 upcycling project: around 1,500 decommissioned MRT train seats were converted into benches at void decks across Yishun, Bukit Panjang, Choa Chu Kang and Bukit Batok.

For travellers, this is the side of Singapore most visitors miss — the heartlands, where daily life happens a short MRT ride from the marina and the malls. All these spots are free, reachable by public transport, and give you a genuine feel for the neighbourhoods locals actually live in. Bring a book to swap, an empty stomach for the vending machine supper, and a bit of curiosity.
