Enclosing patio to use as sunroom around the year. Any suggestions

[vivimimi]

Hi, We have an open patio with decking and wooden frame (see pic). We are considering to make it into an enclosure (6m x 2.5m). We don't want to make it into a conservatory with bricks and glass. We want to maximise the opening.

Roof: We are considering polycarbonate roofing and
Sides:
a) polycarbonate sliding doors on sides or
b) glass sliding doors on all three sides
c) any other suggestions
Floor: Carpet with underlay on top of current decking boards.

Ideally would like to retain the timber structure, we spent a lot to build the decking last year. We want the flexibility to open the enclosure during the summer days.

Any suggestions or new ideas?

My suggestion might be against the grain, but would honestly be don't do it, as the room inside will just be super dark all the time and basically a corridor
The best day we had was the day we knocked down our old conservatory and suddenly the room behind it was so light rather than a cave.
I would recommend trying to build something a little further away, maybe a garden room or similar.

just what I was going to say OP

It sounds like it’s basically a lean to and you will need PP given you’ve already extended out. With no foundations I can’t see how it would work properly.

Our friends had a similar wooden structure and have put plastic awning walls up which roll up and down and have windows in. Works really well. I think they got them made to measure.

thank you @johnd2 @Thighdentitycrisis ; I'm not considering a conservatory with part bricks and glass; rather considering full glass or polycarbonate or as suggested by @BonnyandPoppy the plastic awning. That should allow maximum light through. Plus in our extension we also have a skylight lantern that floods lot of light through.
@NewHouseNewMe let me check on the PP, I was told that temporary structure no PP is required. Yes if I do foundation work etc I will require PP.

@BonnyandPoppy thank you for the idea, I dropped you a PM.

I have a lot of experience of these kind of structures through my work .....poly carb dates really quick and will look shabby within a year or so. If you have to do that then put a nice lattice work frame on the underside to hide it. I'd personally look at electric retractable blinds that go inbetween the roof timbers. That way in the summer you can still enjoy the sun. Glass sliding doors will cost you a lot! Probably as much as knocking it down and doing a cheap conservatory - glass is very expensive at the moment. Id maybe infill the lower sections with timber and then glaze the top or use a vertical blind. I wouldn't carpet the floor. It's not an insulated floor so the carpet will rot and you aren't fully weather proofing the structure. Lay an outdoor tile.

Carpet will almost certainly rot. You can get nice outdoor rugs - I'd use those instead.

@breatheintheamazing thats interesting. thank you. I know poly carb gets yellow and looks shabby. Can you tell me bit more about electric retractable blinds - could you share link. Are these ok with winds and storms? Outdoor tile is a great suggestion. Will look into that.

Polycarbonate doesn't go yellow, that's acrylic. PC is the more premium option.
Regarding conservatory and light, actually ours was 100% glazed. But even new clean glass only has 70% light transmittance. Then add in the frames for another 70%.
Any kind of non glass would be worse, especially once you add the dirt and grime that sticks better. But it sounds like you have considered this anyway.

You also have to think about structure and wind load. A big door or wall made out of flimsy material will act as a sail and get blown out in high winds. Even if you use something less flimsy, you would need to make sure whatever you attach it to can take the load.

It's not that it will go yellow it's more look dirty and green where it holds water they look grim within a couple of winters
Electric retractable are generally fine in all weathers many have a wind sensor on them so that in high windows they automatically close
Depends on what you are after really? If you want 365 day use you're best off getting a conservatory and starting again instead of spending a fortune trying to work with what you have? Or if you are just after a covered area in the summer then outdoor tile, retractable roof, infill the gaps between posts with some nice bespoke planters with a seat attached to them, fire pit in the middle

Thank you all. I found another option that seems a midway. Thank you @BonnyandPoppy I like Cunningham covers I shall give them a tinker.
