Hi I'm Aine, I'm looking to build in Co. Down, Northern Ireland. I'm a total newbie with no experience of self building but enough determination to get me through, all being well. Planning have asked for a flood risk assessment for the site. Does anyone know any reputable qualified individuals in NI that I could go to?

Not sure if it’s ridiculous to consider solid walls for a new build. I have done a lot of googling on the subject, it seems you can get a decent U value without the wall being too thick, some suggesting even thinner than would be required with cavity walls! Im considering it because there is a flood risk, and I believe solid walls are preferable in this situation, water in the cavity wouldn’t be pleasant even if I chose closed cell insulation. Other positives could be, depending on route chosen, dense block work could be a great sound barrier, or it opens up the possibility of more interesting brick bonds. Have double the bricks would be pretty expensive though. I can’t work out if condensation is a risk, some people say it is a risk with solid walls, others think cavity wall insulation will be the next ppi for its damp risks.. That brings me on to the next thing internal or external wall insulation, it seems external is preferable, however internal offers the chance to have more interesting brick work. In my mind I think external would be more effective, however with external surely you will lose a lot of energy heating the dense blocks? You wouldn’t have this with internal insulation. Hmmm. Going around in circles with this one!

Hi, Part of the build is in a flood risk zone, with this in mind I was thinking of spec'ing bricks with less than 7% water absorption, this however limits the choices. Do you think it is worth spec'ing such a low water absorption bricks? Also where do you call it, 7%, 10%, 13% etc. Thank you in advance
