The 80 new three-generation (3Gen) HDB Build-to-Order flats will be located at Saraca Breeze @ Yishun, close to Khatib MRT Station, revealed National Development Minister Khaw Boon Wan on Saturday.

Writing on his blog, Mr Khaw said this will put the pilot launch of 3Gen flats -- first announced last month and meant to encourage multiple generations to live under one roof - in the vicinity of an eating house, a minimart, shops and a childcare centre.

His post also included the floorplan for these apartments, which will come with four bedrooms, two of which have attached bathrooms.

The layout was tailored to be elderly-friendly and "sensitive to the needs of two families living under one roof".

The internal floor area of 115 sq m is 5 sq m larger than current five-room units, and can be resold in the open market only to other eligible multi-generation families.

Applicants need to comprise at least a married or courting couple and their parents, and rooms cannot be sublet during the five-year minimum occupation period.
