New here and inexperienced in this world so I’ll keep my post short and invite questions from anyone with more knowledge and experience. We have a 3 bed 1930’s semi and are looking to extend out the side and back and knock through kitchen and dining room. Side extension would go out 1m and is circa 11m² in total. Back extension is circa 14m² and would require the removal of the current conservatory in order to build a brick structure which would have full glass doors opening out onto the patio and garden. We believe this job will require a number of steels as the internal wall is likely to be supporting and one of the other walls to go is the external side wall. Rough drawings attached. Is it possible? Considerations? Estimated cost? Any other things to think about?

We have recently transformed our garden space to open it up for a large patio area, which has all been laid, and the final touch is to add 10-20mm decorative shingle around the slabs for the border and also to create a small area which is purely going to be decorative shingle (2.5m x 3m). A couple of questions: 1. For the border which is 100-150mm deep, I am going to use pea gravel to start with and then top up with the decorative shingle - say it is 150mm deep, would you go 100mm pea gravel and 50mm shingle, or more/less either way, or does it not really matter? 2. For the 2.5m x 3m area it has been prepped with compressed type 1 MOT and heavy duty weed control so is the final step quite literally as simple as throwing down the decorative shingle and raking out to match the level of the patio? Any other considerations?
