Types of Houses and Characteristics of a Good House

Learning objectives

• Define housing and classify common house types by structure, materials, occupancy and permanence.
• Explain how housing conditions affect infection, respiratory health, injuries, nutrition, mental health and dignity.
• List the characteristics of a healthy and ideal house, including site, construction, WASH, ventilation, lighting, safety and accessibility.
• Conduct a basic housing-health assessment and recommend feasible improvements.
• Recognise urgent hazards such as fire, carbon monoxide, overcrowding, damp/mould, flooding and structural instability.

1. Housing and health

Housing is the dwelling and its immediate environment in which people live, sleep, cook, store food, care for children and recover from illness. Healthy housing prevents exposure to hazards while supporting comfort, privacy, social wellbeing and resilience.

Housing condition	Health pathway	Possible outcomes
Overcrowding and poor ventilation	More close contact and contaminated air	Respiratory infection, tuberculosis transmission, asthma and poor sleep
Dampness and mould	Allergens, irritants and persistent moisture	Wheeze, asthma exacerbation, respiratory symptoms and skin irritation
Unsafe water/sanitation	Faecal–oral transmission and poor hygiene	Diarrhoea, cholera, helminths, trachoma and reduced dignity
Polluting cooking fuels	Smoke and carbon monoxide in poorly ventilated rooms	Pneumonia, COPD, asthma, cardiovascular disease, low birth weight and poisoning
Injury hazards	Falls, burns, cuts, electrocution, unsafe stairs or open fires	Trauma, disability, death and childhood injury
Vectors and pests	Insects, rodents and contaminated food/water	Malaria, dengue, leptospirosis, food contamination and bites
Extreme heat/cold and disasters	Thermal stress, flood, wind or structural failure	Heat illness, hypothermia, drowning, displacement and disease outbreaks
Insecurity, noise and lack of privacy	Stress, poor sleep and reduced ability to study or recover	Anxiety, depression, violence risk and reduced wellbeing

2. Types of houses

2.1 By permanence

• Temporary/emergency shelter: tents, tarpaulin shelters, transitional units or improvised dwellings. Rapid to erect but may have poor thermal comfort, privacy, fire safety and durability.
• Semi-permanent house: locally available materials with a more durable frame, floor or roof; can be upgraded gradually.
• Permanent house: engineered or well-constructed materials designed for long-term occupation and maintenance.

2.2 By materials and construction

Type	Strengths	Health and safety concerns
Traditional earth/mud, wattle-and-daub or thatched	Affordable, locally available, culturally familiar and potentially cool.	Moisture damage, collapse if poorly maintained, smoke accumulation, pests, leaks and fire risk.
Brick/block or stone masonry	Durable, can provide thermal mass and secure walls.	Damp rising, poor ventilation, unsafe construction, dust or asbestos-containing materials in some renovations.
Timber or prefabricated	Quick construction, light and adaptable.	Fire, termites, rot, poor insulation, unsafe wiring or weak foundations if not designed well.
Metal-sheet or container-based	Rapid, transportable and durable roof/wall option.	Heat gain, condensation, noise, sharp edges, poor ventilation and inadequate insulation.
Mixed-material	Can combine local materials and affordability.	Junctions may leak or harbour pests; quality depends on design and maintenance.

2.3 By occupancy and layout

• Detached single-family: privacy and control over yard, but may have higher costs and isolation.
• Compound or homestead: several dwellings around shared cooking, water, sanitation or livestock areas; planning is required to prevent contamination and fire spread.
• Multi-family/tenement/apartment: efficient land use but shared water, toilets, waste, stairs and ventilation require strong management.
• Hostel, dormitory or institutional housing: higher density; needs infection control, safe sleeping space, toilets, bathing, food and emergency exits.
• Informal/slum settlement: may be structurally variable and lack services; health action should address infrastructure and rights, not blame residents.

2.4 By urban or rural setting

Urban homes may depend on piped water, shared toilets, electricity and waste collection; rural homes may depend on springs, wells, latrines, biomass fuels and agricultural land. Neither setting is automatically healthy. The assessment must examine actual conditions, affordability, service reliability and local hazards.

3. Characteristics of a good house

3.1 Safe site and neighbourhood

• Stable ground away from flood plains, landslide zones, contaminated land, industrial emissions and dangerous traffic.
• Good drainage with no stagnant wastewater around the house; rainwater directed away from foundations.
• Safe distance and downhill/down-gradient placement from latrines, septic tanks, refuse pits, animal pens and chemical stores according to local technical guidance.
• Access to roads, health care, schools, markets, emergency services and safe transport.
• Community security, lighting, privacy and protection from violence, discrimination and exploitation.

3.2 Strong and healthy structure

• Sound foundation, walls and roof that resist local wind, rain, heat, termites and other hazards.
• Waterproof roof and walls without persistent damp, cracks, holes or unstable ceiling.
• Smooth, cleanable floors raised above wet ground; no dangerous protrusions or loose boards.
• Safe doors and windows with locks, screens where appropriate and accessible exits.
• Materials that do not release hazardous dust, lead, asbestos fibres or toxic fumes; renovations should use trained workers.

3.3 Space, privacy and accessibility

• Enough floor and sleeping space to reduce overcrowding and permit movement, rest and care.
• Separate or private spaces for sleeping, cooking, bathing, toileting, menstrual care and breastfeeding where feasible.
• Accessible routes, ramps, handrails, wide doors and usable toilets for people with disabilities, older adults and injured patients.
• Safe sleeping arrangements for infants; protect children from falls, fire, drowning and unsafe storage.

3.4 Ventilation and indoor air quality

• Openable windows or mechanical ventilation that provides cross-ventilation without creating dangerous drafts.
• Cooking smoke vented outdoors through a chimney/hood or replaced with cleaner fuels and technologies where possible.
• No indoor charcoal/wood stove in a closed room, no idling engine indoors and no use of generators inside the dwelling.
• Reduce tobacco smoke, burning waste, strong chemicals, dust, mould and overcrowding.
• Keep vents and windows clean; do not block them permanently for security without an alternative airflow plan.

3.5 Natural and artificial lighting

• Daylight for safe movement, study, cooking and cleaning; avoid glare and overheating.
• Safe electrical wiring, switches, sockets and lamps; protect children and keep combustible materials away from heat.
• Emergency lighting and visible house numbers/paths where possible.

3.6 Safe water, sanitation and hygiene

• Reliable safe water for drinking, cooking, handwashing, bathing and cleaning.
• Toilet that is safe, private, accessible, well-drained and hygienically managed; child faeces disposed of safely.
• Handwashing station with water and soap at the toilet and food-preparation area.
• Covered food-storage space, cleanable surfaces and safe wastewater disposal.
• Waste bins with lids and a collection/disposal route; no dumping or burning of hazardous waste near the home.

3.7 Vector, pest and animal control

• Window/door screens or bed nets where indicated; eliminate standing water and protect water containers.
• Seal cracks, store food securely, remove rubbish and control rodents/cockroaches using safe integrated methods.
• Keep livestock, poultry and pets separated from sleeping, food and water areas; manage manure safely.
• Maintain roofs, gutters and drainage to prevent mosquitoes and dampness.

3.8 Thermal comfort and climate resilience

• Design for shade, airflow, insulation and safe heating/cooling appropriate to the local climate.
• Protect occupants during heatwaves, cold spells, storms, floods and drought-related water shortages.
• Secure roofs and heavy objects; identify evacuation routes and keep emergency supplies.

4. Housing hazards and practical controls

Hazard	Warning signs	Control
Overcrowding	Many people sharing one sleeping room, poor airflow, recurrent respiratory disease	Reduce crowding where possible, improve ventilation, arrange safe isolation and advocate for adequate housing.
Damp/mould	Musty smell, wet walls, condensation, visible mould, cough/wheeze	Find and repair leak, improve drainage/ventilation, dry materials, remove mould safely and assess respiratory disease.
Household air pollution	Smoke haze, soot, eye irritation, cough, child pneumonia or CO symptoms	Clean fuel/technology, outdoor or ventilated cooking, chimney/hood, no indoor generator, CO awareness.
Fire/burns	Open flame, unstable stove, fuel stored indoors, no exit	Stable stove, safe fuel storage, child separation, extinguisher/sand, smoke alarm where feasible and evacuation plan.
Falls/electrocution	Unsafe stairs, loose rugs, exposed wires, wet floors	Handrails, lighting, dry floors, repair wiring, socket covers and keep medicines/chemicals locked.
Unsafe water/sanitation	Dirty container, overflowing latrine, no handwashing station	Protect source, treat/store water, repair toilet, provide soap and safe child-faeces disposal.
Lead/asbestos/chemicals	Old paint/dust, damaged roofing, pesticide/fuel/solvent storage	Do not sand/burn unknown materials; isolate, use trained removal, label chemicals and contact authorities.
Noise/insecurity	Poor sleep, fear, violence, inability to rest	Safe lighting/locks, community protection, referral for violence, noise reduction and social support.

5. Basic housing-health assessment

1. Ask permission and ensure privacy: explain the purpose; do not shame the household.
2. Assess people: infants, older adults, pregnancy, disability, chronic disease, respiratory symptoms, injuries and mental wellbeing.
3. Assess the site: flooding, drainage, waste, animals, vectors, industry, road and disaster risk.
4. Assess the structure: foundation, roof, walls, floor, windows, exits, damp, mould, smoke and wiring.
5. Assess WASH and food: water source/treatment/storage, toilet, handwashing, food preparation, waste and wastewater.
6. Assess occupancy and safety: sleeping space, privacy, violence, fire, falls, chemicals and accessibility.
7. Agree priorities: immediate danger first, then low-cost improvements, then structural/service advocacy.
8. Refer and follow up: link to health care, environmental health, social protection, housing, disability and protection services.

6. Immediate hazards and emergency response

• Suspected carbon monoxide: move people to fresh air, call emergency services, do not re-enter until the source is made safe; assess headache, confusion, collapse and pregnancy risk urgently.
• Fire: raise alarm, evacuate, crawl under smoke, stop-drop-roll for clothing fire and cool burns with clean running water; do not return for belongings.
• Flood or structural instability: evacuate early, avoid electrical hazards and contaminated water, and do not re-enter until assessed.
• Child poisoning: remove exposure, keep container/label, do not induce vomiting, contact poison/emergency services and monitor airway/breathing.
• Severe respiratory symptoms from damp/smoke: remove exposure, treat acute asthma/respiratory distress according to protocol and arrange environmental correction.

7. Ideal homestead planning principles

• Place the dwelling, kitchen, toilet, refuse area, animal shelter, garden and water point so flows of people, water and waste do not cross.
• Direct clean rainwater away from the house and dirty water into a safe soakaway or drainage system.
• Keep food preparation separate from livestock, latrines, waste and chemical storage.
• Provide shade trees and safe outdoor space without blocking ventilation or creating mosquito breeding sites.
• Ensure an accessible path, emergency exit, lighting and a place for safe menstrual, child and elder care.
• Use local materials safely, maintain roofs and gutters and plan for incremental improvements rather than waiting for a perfect house.

8. Uganda context and references

Housing standards should follow Uganda building, environmental-health, water and sanitation requirements and local authority guidance. In rural and urban settings, health workers can achieve major benefits through practical improvements—ventilation, safe stoves, drainage, protected water, toilets, bed nets, reduced crowding and child safety—while advocating for structural housing and service investment.

2. It dilutes infectious aerosols and removes smoke, heat, moisture and pollutants.
3. Safe water, protected storage, accessible toilet, handwashing with soap, wastewater drainage, safe food preparation and waste disposal.
4. Move people to fresh air, call emergency help and do not re-enter until the source is made safe.
5. Covered water, bed nets/screens, remove standing water, seal food, control waste/rodents and separate animals.
6. Many hazards reflect poverty, infrastructure, disability or unsafe services; respectful support improves uptake and equity.

Key takeaways

• A healthy house integrates structure, air, water, sanitation, food, safety, space, privacy and accessibility.
• Overcrowding, damp, smoke, unsafe water, vectors and injury hazards are preventable environmental-health risks.
• Assess immediate danger first, then agree realistic household improvements and referrals.
• Healthy housing is an equity issue; policy and service investment are as important as individual behaviour.
