3 Concepts, 3 Meanings: Clear Definitions for Elderly Families
When real estate projects use the terms Wellness Home, Smart Home, or Accessible Home in marketing, families often do not know what they will actually receive. This article provides verifiable definitions and the specific questions to ask every project.
Concept 1: Accessible Home
Definition: A home designed or retrofitted so elderly and disabled residents can live without physical barriers.
Required specifications (verifiable):
- Door clear opening ≥90 cm (walker) / ≥120 cm (wheelchair)
- Door threshold maximum 13 mm
- Bathroom floor COF ≥0.6 (non-slip)
- Grab rails at 2 bathroom points (shower + toilet)
- Lift clear width ≥1.1 metres
- Ramps replacing steps, gradient ≤1:12
Does not require: IoT systems, sensors, or any smart devices.
Retrofit cost to achieve Accessible standard: 40 sqm unit: 15,000–35,000 THB (grab rails, anti-slip flooring, door adjustment)
Concept 2: Smart Home
Definition: A home with IoT systems that detect, alert, and automatically control the environment.
Required specifications:
- At least 1 sensor type (PIR, mmWave, Door Sensor)
- Connectivity to an app or alert system
- At least 1 automation rule
Elderly-specific additions:
- mmWave (sleep monitoring)
- Panic Button
- LINE Notify / Family Alert
Important: Smart Home does not require Universal Design. A room may have high door thresholds but full sensors — or vice versa.
Cost: Track A 5,000–10,000 THB / Track B 25,000–50,000 THB
Concept 3: Wellness Home
Definition: A home integrating Accessible Design + Smart Technology + Environmental Management to support physical and mental health.
Required specifications across 3 dimensions:
Dimension 1 — Physical (Accessible): Doors ≥90 cm, grab rails, non-slip flooring, light ≥300 lux
Dimension 2 — Technology (Smart): mmWave, Circadian Lighting, Smart Pill Dispenser, Family Alert
Dimension 3 — Environmental: Air quality PM2.5 <15 μg/m³, temperature 24–26°C, noise <45 dB, natural light ≥2 hours daily
Difference from Smart Home: Wellness Home adds air quality management, circadian lighting, and acoustic control — elements standard Smart Home systems typically neglect.
Full Wellness Home cost: Accessible Retrofit + Smart System + Air Quality System = 45,000–90,000 THB
Checklist: Verifying Project Claims
If project claims Accessible Home, ask: ☐ What is the exact door clear width? ☐ What is the bathroom floor COF rating? ☐ Are grab rails included at shower and toilet?
If project claims Smart Home, ask: ☐ Which sensors are pre-installed? ☐ What app does the system connect to? ☐ What is the ceiling height (does it support mmWave mounting)?
If project claims Wellness Home, ask: ☐ Is there an in-room air quality monitoring system? ☐ Is the lighting circadian-capable? ☐ What WELL or LEED certification does the building hold?
