Sun blinds on western balcony?

Hi all,

I did a search for the answer to this, closest I came was a thread on Plantation Shutters.

Here goes – we are on the OC for a SP where approx. 80% of the units face west. Units are 2 story brick, with sliding doors out onto upstairs balconies, west facing. The balconies have gables over them, however the late afternoon sun is ferocious this time of year, and substantial heat is transferred into the upstairs rooms.

A polite owner has asked if they can put up external blinds to stop the sun.

This us seen by the OC as a very reasonable request.

However the OC doesnt know how to politely guide the requesting owner and any others who may follow, if indeed that is possible.

How can we somehow, without being too prescriptive, manage things like

-colours

-fixings

-style.

-Issues down the track with maint. of CP where the fixings have caused an issue? e.g rusty fixings cause staining of CP tiles, or whatever.

The SP is a nice property and all seem keen to keep it that way.

The OC wish to approve the blinds as it is a sensible request, just nervous about the can of worms we may open .

Thanks in advance
