I think a full width deck is more appropriate.

I would add a deck that runs full length also I would also add railings to finish the look.

Full width is also a bit safer. Concrete and/or brick would be maintenance free materials that you could use.

I agree that would give the area a finished look

Sunrooms are a great way to improve living quality in
your house as well as increasing the value of it. Enjoy outdoor experience on a
rainy or cold day and watch the stars at night – bring the outdoors inside and
extend the time you can enjoy it. Besides the design of your new sunroom, you
must consider how to bring shading to it - you don’t want to sit in a glass
house and get cooked.

The shades should easy adapt to your shading and privacy
needs for example with a bottom up top down operation for pleated blinds, roman
shades and venetian blinds.

Must be able to cover triangles and odd shapes (most
sunrooms have some non-squared glass)

Must be able to be installed overhead for skylight or similar

Must be minimalistic to keep the open sunroom feeling

Must be available in many colors, prints and designs to
choose from

Sunrooms and window treatment go hand in hand for a
perfect sunroom experience.
