Now that our roof is on ( well, all bar a Velux and a bit of the ridge) I need to give some thought to our cladding.

The whole house is to be timber clad; most of it is fine - standard stuff. Have a look at this 

 

The area that concerns me is this one: ..... (Text accentuated in blue). The cladding encloses an unheated area (called the Winter Garden - more sexily I heard Piers Taylor call a similar design a Breeze Corridor)

 

Put slightly differently, what we need is hit-and-miss boarding so that the garden below and behind it can get plenty of light and lots of air.

 

This is what it looks like now.....

 

As you can see, the hit and miss boarding has - as yet - no framework to support it - except the steels that surround the area.

I need to screw a wall plate all the way round the edge of the steels; that much even I can see.

 

But the cladding (hit and miss boarding)  will need a framework on which to sit.

Is this an SE job, or use-yer-loaf, or a go and ask to see what local farmers do job?   

 

Got a table saw ...??

 

run some tantalized 4x2 through the saw with a 22 degree bevel so it sheds water to make horizontal rails. 

 

Then it’s as per your design with just the vertical boards and gaps. Have a look at any new cow shed for inspiration....

Search "Yorkshire boarding" for what they do on cow sheds. That has open gaps between boards.

 

I wonder if you could do that combined with a really well applied & taut black membrane behind...or st/st mesh. 

 

Or maybe like hit and miss fencing...

Thats the intention. The mesh will have to be fitted round our bat and swift boxes - we really hope they'll visit us one day.

I would fit the front boards and add the mesh from behind then fit the rear boards with screws so you can remove for maintenance in the future. 1/2” fine S/S Mesh is available in big rolls.
