I don't know if this makes any sense to you lot, but I asked that very question to the After Sales people at Parador, and the reply was as follows:
Dear Mr. and Mrs. Blanchard,
Thank you for your e-mail which Paul kindly forwarded to me.
It is not compulsory for first floor windows to be fitted with grilles. When residents start moving in at the Country Club the committee, together with the residents, will decide which type of grilles will be used. Huma want the site to look uniform.
If you wish I can pass your contact details to my colleagues in our Parador Choice department. They will be able to issue you with a quotation for grilles. A return e-mail would be fine.
If I can be of any further assistance please do not hesitate to contact me.
Kind regards from Torrevieja,
Denise
Hope this clears things up, but I doubt it very much!!!!
