I love rollerblinds for their neat, sophisticated look. Venetians are a nightmare to clean... x) Plantation shutters are worth the investment. Low maintenance and good in wet areas where fabrics/wood may not be so good. I have a mix of plantation shutters and rollerblinds, with a few curtains. :)

Off the shelf blinds are usually mass produced imports hence being significantly cheaper. A custom made blind will fit exactly how you want it and like ours, Australian made! Also it depends on where you want it fitted, ours is between the timber reveals but they could be fitted to the architraves (wooden trim around the window).

Hi Relly72, It looks like you have lovely panoramic view. I would suggest installing the blinds. Make sure they have a transparency (i.e.- not black-out). They will filter the intense light in the summer. (I'm not sure where you're located but if you're in Australia, a northern sun can be very strong at noon and you will want to have some control over the intensity of the sun/heat and to protect the furniture and flooring.) I would also suggest putting the system on your wifi network, then it can be adjusted while you're out of the house to minimise air-condition use/costs or the need to ventilate the minute you enter the house. Curtains can easily be added at a later date if you want to soften the feel of the space.

I have translucent on stacker to alfresco, It's great as don't need it for privacy, just for reduced sunlight at times and if wanting air con to be more energy efficient. It is lightweight so you can have a large expansive without doing 2 or 3 blinds. I have double roller blinds i every other room. Blockout and sunfilter. Love them, and how you have choice to let light in, and blockout in our master bedroom during day for shift worker hubby. I have white as it was recommended to reflect most sunlight, not absorb it. Black looks great and is more transparent from the inside so if you get the 'sunlight screen' type you can see through very clearly, but people cant see in, until it gets dark, then you roll down your blockout blind for privacy at night. The 'white' sunfilter is not as see- through as the black from inside.
