Underground and above-ground shelters both serve to protect against blast waves and debris, but they have their differences. Let's take a look at them below.
 
Ground shelter: 
 
1. Cost: Elevated shelters are more expensive to produce due to the large amount of concrete involved. 
2. Installation: Faster installation (1-2 days). 
3. Delivery: Shipping cost is higher due to the weight of the concrete. 
4. Thermal insulation: Harder to heat. 
5. Project and land works: Does not require earthworks and project. 
6. Groundwater: Does not matter where groundwater is located. 
 
Underground Shelter: 
 
1. Design and timing: Requires a design (timeframe up to 2 months). 
2. Earthworks and waterproofing: Expensive earthworks and waterproofing. 
3. Cost of construction: Cheaper construction. 
4. Thermal insulation: Easier to heat. 
 
Choose what suits your needs and capabilities. Regardless of the type you choose, it is important that the shelter is reliable and guarantees safety in case of emergency, which is what Hobbit House will help with.
