Why is ribbon development along rural roads discouraged?
- It uses too little land for each of the houses built
- It is too dense for broadband to reach
- It harms road safety, landscape and services
Show the answer
It harms road safety, landscape and services
A string of houses with separate entrances creates many conflict points on the road, urbanises the countryside and makes water, sewer and transport services costly.

Where can you check if a site is in a High Radon Area?
- The Land Registry folio
- The EPA radon map
- The OPW flood maps
Show the answer
The EPA radon map
The EPA map predicts the share of homes in each area likely to exceed the reference level. A radon barrier is expected on new houses anyway, but the map guides extra measures.

Why is a site sheltered by trees or a hill on the north side a good choice?
- It blocks the midday sun
- It makes the site easier to flood
- It protects the house from cold winds
Show the answer
It protects the house from cold winds
Cold winds strip heat from walls and cause draughts. Shelter to the north and west cuts heat loss while leaving the south open to the sun.

Why avoid building a house on a flood plain?
- It gets no sunlight for most of the year
- The site may flood and damage the house
- The ground is too hard to dig foundations
Show the answer
The site may flood and damage the house
Flood plains beside rivers flood in heavy rain. A house there risks water damage, costly insurance and unsafe access.

Why is a site close to a road and mains services a good choice?
- Connecting water, power and access costs less
- The house will then need no foundations at all
- It will not need planning permission
Show the answer
Connecting water, power and access costs less
Bringing electricity, water and a driveway a long way is expensive. A site near a public road and services saves money and time.
