Is this a BTO on level 37 at 291A Jurong East Street 24?

You: No, HDB BTO projects typically max out at around 40 storeys, with the tallest confirmed launches like Berlayar Residences reaching up to 46 storeys. Level 37 is possible in high-rise BTOs (e.g., some in Tengah or Dover sites), but it's rare and depends on the specific project's design—check the floor plans on EdgeProp Singapore for your BTO details.
