Aging-in-Place Design for a 2-Storey Bekasi Home: 70 m² Setup

Indonesia's Bureau of Statistics (BPS) reported in 2024 that the proportion of citizens aged 60 and over has reached 11.7% of the population, projected to hit 16% by 2035. For middle-class Bekasi families currently in their 35-45 age range, that means within 10-15 years one parent is likely to move in — whether for health reasons, loss of a spouse, or care cost considerations.

The problem is that most 2-storey cluster homes in Bekasi are designed assuming all residents can climb stairs comfortably. When a 70+ year old parent starts using a cane or wheelchair, a home that fit the family at purchase no longer works. Renovating after 5 years of occupancy is more expensive — and more disruptive — than planning for it upfront.

This is a guide to setting up a 70 m² 2-storey home for an aging-in-place scenario before it becomes urgent.

Aging-in-Place Principle: The Ground Floor Must Be Self-Sufficient

Aging-in-place means residents can stay in the same unit even as mobility declines, without moving to a care facility. For a 2-storey home, this requires one core condition: the ground floor must function as a standalone living unit.

That means the ground floor should include at minimum:

• One bedroom of at least 9 m² (enough for a 160×200 bed plus side table)
• One bathroom accessible without stairs
• Access to dining and kitchen with no level changes
• An exit (carport or side door) that's wheelchair-friendly

The Emerald 70 type at Kingspoint Private Residences already has a guest bedroom and guest bathroom on the ground floor. The base layout is suitable for aging-in-place, provided minor renovations happen before parents move in.

Technical Specifications for an Elderly-Ready Ground Floor

Senior bedroom

Universal Design Living Lab guidelines recommend:

• Door clearance minimum 80 cm (cluster homes typically come with 70 cm — needs widening at renovation)
• Light switch height 90 cm from floor (default 130-140 cm — too high for someone in a wheelchair)
• Extra outlets beside the bed (for nebulizers, oximeters, night lights)
• Motion-sensor night lights so the elderly don't fumble for switches at night

Anti-slip bathroom

The Indonesian Ministry of Health reports that 70% of falls in elderly home accidents happen in the bathroom. Recommended specs:

• Floor tiles rated R10 or R11 (high anti-slip rating) — not standard glossy tiles
• Grab bars beside the toilet at 80 cm height, rated for 130 kg load
• Grab bars in the shower or bath area
• Toilet height 45 cm (above the standard 40 cm — easier sit-and-stand)
• Adjustable handheld showerhead, not a fixed overhead shower
• Floor slope 1:50 toward the drain to prevent puddles

Step-free access

Often-missed checks:

• Main door: avoid steps over 2 cm at the threshold
• Carport to front door: if there's a step, add a ramp at 1:12 grade for manual wheelchairs
• Bathroom door: bypass the typical step threshold (added to keep water in) using a threshold ramp or drain mat

Common Misconceptions

"The senior room can just be on the second floor"

This works for a 60-65 year old who's still active. But projecting 10 years out, a 70+ year old with knee or hip issues will struggle with daily stair use. Forcing daily stairs also raises fall risk, the leading cause of non-medical death among Indonesian elderly per Riskesdas.

"We can install a stair lift later"

Stair lifts cost IDR 35-80 million for a straight cluster home staircase, and U-turn staircases often need custom units at IDR 100-150 million. Compare that to setting up a ground-floor bedroom — much cheaper, and the room stays usable as a guest room or office until needed.

"Renovate when parents have already moved in"

Renovating with elderly parents already in the home means temporary relocation — costly hotel stays and stressful for the parents. Pre-renovation flows much smoother. Plus, post-occupancy renovation risks damaging finishes already in daily use.

Ideal 70 m² Emerald Layout for Aging-in-Place

The Emerald 70 floor plan at Kingspoint Residence is relatively well-suited for adaptation:

• Ground floor: guest bedroom + guest bathroom + family room + kitchen — all stair-free
• Second floor: master bedroom + children's bedroom + family bathroom — for owners and kids

A reasonable strategy: years 1-7 after move-in, the ground-floor bedroom serves as a guest room or home office. When parents start moving in (year 7+), convert it to a senior bedroom with the IDR 12-18 million renovation above.

The key: budget for renovation as part of the original home purchase plan, not when parents are already declining. Health-driven renovations under time pressure are the worst time to make these decisions.
