Kieran McCarthy: Is a dormer bungalow much more expensive than a bungalow?

Most engineers will design the same foundations for a bungalow as for a two-storey house, even though there is clearly less weight per metre of foundation

The bungalow was relatively simple to build, as it didn’t require a significant amount of scaffolding, so it didn’t always require a very experienced main contractor to build it.

Hi Kieran 

Is a dormer bungalow much more expensive than a bungalow (of comparable floor area) to build?
