Cost of Flood Resilience

[Ferdinand]

Listening to the radio this morning, a prominent Construction Policymaker was talking about the cost of making houses flood-proof or resilient.

 

It seems to involve things like heating gubbins in the roof etc, and the cost seemed to be adding a putative 10%.

 

Does anyone have any ideas as to what is needed, or thoughts on the cost?

 

(Remembering the scary numbers sometimes quoted about the cost over par of passive.)

We have built near a river.  The houses have brick and block ground floor, rigid insulation, electrics set above 1100 from ffl, suspended concrete ground floor, with flood proof airbricks and porcelain tile finish.  Ground floor walls are rendered internally.  Ground floor use non-habitable (store, gym, office etc.  Bedrooms, kitchen etc. located on upper floors.)  Skirtings and a few areas are sacrificial.

 

We are also looking at adding some flood barriers for ground floor openings at a cost of about £2,200 per house.

In the village i lived in down south one cottage by the river regularly flooded, but only to a few inches deep when the river came up.

 

They had made it resilient by quarry tiling the entire ground floor including quarry tile skirtings.  All electrics were well up the wall.  The kitchen units were on taller than normal legs.

 

When the flood came, the furniture went up on blocks and the kitchen kick boards came off.

 

When the flood went down it was a case of mop out and put everything back.

 

Due to the location the tenant had to wear a pair of waders to get in and out, sometimes even when the cottage was not flooded.  Oh and remember to park his car further away.
