Loft extension layout dilemma- help please!
Hi, it’s my first time posting. I am hoping for some help working out the best layout for a possible loft conversion.
I live in a double-fronted Edwardian house in SE London, end of terrace. Lots of lofts locally have been extended with a dormer, under permitted development, so that shouldn’t be an issue. The extension should just come in at under 40m3. The house has a hipped roof on one side and I think I’d probably convert that to a gable end. Most people have put a bedroom on either side of the central stairs, with a bathroom in the middle opposite them. I’m hoping to do something slightly different. Ideally one bedroom with a reading nook/possible home office area and a bathroom.
I want it to feel spacious, light and airy and use the space cleverly, so it doesn’t feel like lots of nooks and crannies and wasted space. Possibly a walk in wardrobe?
The main limiting factor (other than budget of course) is that the front of the house has solar panels on most of the roof that I don’t want to have removed. This limits where I can put velux windows, and therefore affects light inside the conversion. Velux windows could only go on the front of the roof in the small new area created by a gable end, or there could be windows on the new flat roof part of the dormer. I could potentially put a window in the new gable end as well, which I’d be quite keen to do as it is south facing.
The main question I am wrestling with is where the bathroom would be best placed to be and reading nook/office, to make use of the light and views. I have attached some drafts of plans from the architect. The architect has suggested moving the staircase to make a large open plan space upstairs but I am not keen as I feel this would significantly increase costs and also compromise 2 bedrooms on the first floor. When the staircase is not moved the study area upstairs becomes very tiny and seems quite disappointing. I wondered about the dormer coming out less than 3.6m and then the space being wider? The alternative would be to have the bathroom where the study area is. I was keen to avoid this as I was hoping to have flexibility to put a stud wall up in future so that the upstairs could be 2 separate bedrooms if desired (not that we will need it for that, trying to future proof!)
I have not put measurements on for the wardrobe/ bathroom, advice on sizes would be helpful, taking into account the sloping roof/ ventilation/windows!
I have attached some photos of what I was thinking of re-the bathroom/ walk in wardrobe.
Really looking forward to hearing your suggestions, particularly with regard to making use of the light and space.
