I'm adding some deeper joists
to form a floor in the front part of my loft. A full loft conversion is planned for the future but this will be at the back of the house. The front will be for eaves storage - but we have a lot of stuff so realistically the loading will be quite high. I'll use 175 or 200 x 50 at approx 400mm to span 3.4m. I want to drop the joists to finish a bit (60mm)below the existing 70mm ceiling joists as headroom is tight in the loft. The joists sit directly on the brick spine wall internally so I'll be able to cut slots in the top of this to drop the new joists in. On the eaves end the joists sit on a 75mm deep timber wall plate. How can I fix the joists? I could notch 60mm out of the joist ends to sit them on the wall plate and support the bottom section with timber mini joist hangers? I don't think I could get far enough into the eaves to either build up the wall plate and/or nail a larger hanger securely. It won't be inspected but obviously I want something structurally sound.
Thanks.
