Thanks :) Yeah decided to go with tile. So sand cement is ok over existing tiles if I prep them first? Only problem is, the new pad can only be about 30mm at it's thickest (leaving up to 15mm for tiles) otherwise it'll end up being higher than the hallway floor. So I either need to make the fall shallower or not bother with the waste and make it all level. If I made it level, could I use levelling compound at that thickness or would deck mud/sand cement be the best option? Also, should I be putting in mesh for strength? (I know I should (and will) ask the local hardware what they suggest, but it's great to have suggestions from the Houzz community also)

I agree with havingfun, thicken the supports and have something growing trailing up them. I didn't even notice there was a pergola until the close up. Right now it blends in too well with the house color, consider painting it a different color. I don't know your usda zone but classic climbers for a pergola include clematis, wisteria, grape https://www.houzz.com/photos/santa-ynez-valley-mediterranean-porch-santa-barbara-phvw-vp~2485412 or go for a modern look You can also hang string lights, planters or something from the beams. Also agree lighten the front door.

My last household purchase was new sliding doors to the outside from my dining room. This then led to the building of a deck, new railing on said deck and existing terrace, new blinds as the old window length curtains no longer did the trick, then the paving stone path to the deck from the garden gate, some new planting to accommodate that, AND outdoor lighting for what has now become an alternative entrance to the house! Oh, and painting as well. So I can liken my last purchase to a bit of a triffid - it kept growing! But SO worth it! It has added another room/space to my house, increased light and warmth, added value and created a more welcoming entrance than before. Love it!

I meant to say if we clad in dark blue board and batten from ground level up to floor level of deck. I think if that side wall is all light coloured silvered cedar, the house will look mammoth. Ugh! The black stuff going down the side wall on an angle is water protector. It will be covered by whatever cladding we go with.
