Q

According to VPGA 8, what matters can impact the markets perception on value?

A

Surrounding area - communications and facilities eg wind farms, 5G towers, nuclear power plants, distance from good quality schools/ public transport etc

Property itself - Age, construction, accessibility, fixtures/fittings, improvements, hazards, flooding, contamination, deleterious materials, potential for development or re-development

Q

What is radon?

A

Natural, radioactive, odourless and tasteless gas

Low levels in outside air but collects in enclosed places like buildings, certain parts of the U.K are more prone to it such as Bristol or the Peak District due to the geology of the soil & rock

Shallow foundation that avoids bricklaying below ground by filling trench with concrete. Useful method used in residential and retail buildings as quick and easy. Only issue is that it must be used in areas where soil has good drainage or water can pond in the foundations, weakening them over time.

76
Q

What is a raft foundation and when are they used?

A

Shallow, slab foundation reinforced by concrete slabs of uniform thickness. Typically used to spread the weight of a building over a larger area so typically used in for industrial/warehouse applications, the reinforced concrete literally sits on top of the soil like a raft. Not good to use on clay soils as the clay moves and cracks the shallow slabs.

77
Q

What is a piled foundation and when are they used?

A

Long, slender reinforced concrete cylinders or beams used for large structures. Embedded upright in the ground and used when the soil is weaker as the piles can be buried very deep - good for supporting taller buildings like office blocks

A

Dry rot, wet rot, tile slip on roof, damp penetration, water ingress around door, structural movement around windows
