How to deal with external heating/gas plywood pipe box

Not sure what to do here- somebody might be able to offer some advice or inspiration! Due to a couple of issues when we got our house refurbished prior to moving in eight years ago, we have this unsightly godawful and outright wrong pipe box beside our back door. It houses central heating pipes and a gas pipe that exit the house below floor level in order to return inside at boiler level (I know, I'm well aware it is awful and not the way it should've been done). We're getting our garden done in the coming weeks. This involves outdoor porcelain tiles and accompanying subbase etc. which will inevitably bring the finished patio above the bottom of the box. As I see it, below are my options for how to deal with this: Internally, take up some kitchen tiles and possibly remove the kitchen unit, kango into the floor and around the pipes, and re-route them up to the boiler internally. This would be great, only I am loathe to this option- it is big, messy, and I just don't have time for it. Build a pretty box (treated timber or some sort of composite option) AROUND this existing plywood box when the garden is done. I'm leaning towards option #2. However, this doesn't solve for me the problem that the bottom of the box will still be below patio height. Added to that, I removed the box front yesterday (pictured) and noticed that a part of the frame has finally rotted (I'm really surprised this didn't happen sooner). Insulation is obviously important here. I'm either going to have to replace the rotted piece and build a nice pretty box, dealing with the oddity of the paving being installed AROUND the plywood box, or, do something a little more permanent. What I'm thinking here is (option #3) insulate (using what, other than pipe insulation and expanding foam, as is currently in-place), and box-in (at the bottom at least) using cement board. Wondering if anybody has any thoughts on this, if there's a better way of doing this job? Can pipes sit within expanding foam/insulation outside, below (but nearly level with) a patio? https://preview.redd.it/lqoum876ex0f1.jpg?width=3072&format=pjpg&auto=webp&s=b7c71a4d8f17d596000130bd1db0d6d468bc686e https://preview.redd.it/1z22w876ex0f1.jpg?width=4096&format=pjpg&auto=webp&s=2c11aad591508d6370a5e840783d8aa013fca71f submitted by /u/FrankLedwidge [link] [comments]
