S Quarter

S Quarter is Sansiri’s active-lifestyle destination in Krungthep Kreetha, east Bangkok: tennis, padel, pickleball and football pitches, a wellness floor with ice bath, sauna, pilates and onsen, and the social space between them, open from seven in the morning to eleven at night. The idea is PlayFORMANCE: sport, recovery and company as one day-to-night rhythm. It opens at the end of 2026.

AGEN built the website and the booking platform behind it. The site, in English with a full Thai mirror, sells the rhythm of a day there: the morning start, the mid-day reset, the afternoon, the evening unwind. The booking takes twelve courts and pitches, coaches and equipment into one basket with a court map, live slots and a Next available shortcut, benchmarked against the best court booking in Bangkok.

Members sign in by email code, LINE or Google, hold a wallet with points, check in at the desk, and get their confirmations and reminders by LINE and email. Payment is by card or PromptPay QR through Opn on Sansiri’s own merchant account.

Behind the desk is a staff console of nineteen views and four roles, built for the reception iPad, with S Quarter’s content editor inside it. Next.js and TypeScript in front, a Hono booking API on PostgreSQL behind, running in Sansiri’s own AWS account. Go-live is set for November 2026 at squarterbkk.com.
