Bedroom colder than other rooms

Hi all, i live in a semi detached bungelow which i renovated and built an extension onto a few years ago, the problem i have is that one of the bedrooms at the gable end in the old part of the house is very cold, as far as i can remember there are beams running under the floorboards(this is the only room that has this type of floor) and nothing else, can this be insulated by taking up the boards or would it be better to get a concrete floor put in. The walls are dry lined and there is no dampness on them, also the windows have alot of condensation on them in the mornings. Any help would be appreiciated:cool:

employ an architect/ arch tech to take a look - preferably someone who is familiar with ventilation, air-tightness and heat loss calculations.

yes, you can lift the floor and put down insulation and air-tightness membrane - I would look at this option first before considering concrete. also is there adequate roof & wall insulation?

the condensation is due you breathing and humidity generated condensing on the coldest surface, this combined with a lack of ventilation. open the window at night if someone is sleeping in the room. and asses whether this moisture may be migrating from elsewhere in the house

when your doing the floor, check condition of wall behind dry-lining and come back and tell us. thanks

Thanks for the reply Bryan, the house was built in the 30s and the walls are about 12 inches thick( mass concrete i think they said it was ).The walls are drylined and i had the attic pumped with insulation, i think i will go with the insualtion underneath the floor and see what way this will turn out, It shouldnt cost too much as its not a very large room

retain existing ventilation under the floor. and if there isn't already, install a wall vent
