Currently have 4 beds 3 are decent sized doubles and one is huge with an ensuite. DH will be WFH at least 2 days a week forever and wants a proper study i.e. a room that doesn't double as the spare room for the 2 weeks a year his parents come to stay and is at least 9sqm. We have 2 tweenagers. DH wants to do a loft conversion to provide the extra space. The loft conversion will provide at least 16sqm of head height space in addition to space for a bathroom. DH says he thinks that putting a bathroom in the loft is unnecessary and a waste of money that we can afford. I think that having a small shower room leaves the open option of making the loft space a bedroom (which I'm sure one of the DC will want at some point). I also think going up and down stairs to the toilet, even if its a study is a PITA. I almost think there isn't any point in doing the conversion is there isn't a bathroom. Thoughts please.
