One Chuan Grove Floor Plan & Unit Mix Guide 2026
One Chuan Grove: floor plans will be central to value
One Chuan Grove, formerly known as the Chuan Grove GLS sites, is currently indicated to have 1,056 residential units. Estimated unit sizes are about 44 sqm for 1-bedroom homes; 54–66 sqm for 2-bedroom to 2+Study; 75–93 sqm for 3-bedroom to 3-bedroom Flexi; 100–126 sqm for 4-bedroom; and about 145 sqm for 5-bedroom homes. These sizes are estimates and subject to change, so buyers should check the final floor plans when released.
Two parcels can create different unit experiences
Do not assume the same bedroom type will have identical value across the entire development. Block position, distance to Lorong Chuan MRT, road exposure, internal views and the relationship between parcels can change the attractiveness of each layout.
Family-sized layouts
For 3- and 4-bedroom homes, prioritise practical bedrooms, dining width, service areas, storage and flexible space. A family unit should continue to work when children grow older or when work-from-home needs increase.
Compact layouts and resale supply
Small units can offer lower entry quantum, but a mega-scale development may contain many comparable units. An efficient layout, quieter stack or better orientation can help differentiate the unit later.
Compare with Chuan Park
Once One Chuan Grove plans are published, compare equivalent Chuan Park layouts by internal efficiency and total quantum. A new layout is not automatically better; it should improve function or price sufficiently to justify the choice.
Sean’s Take
In a large development, I would avoid choosing solely by bedroom label or cheapest psf. The better buy is likely to be the unit with efficient internal space, a broadly appealing orientation and a total quantum that remains competitive with Chuan Park.
