It's hard to pick without knowing the context of your wider home but as long as it's not country style, I trust modern to be the most timeless of choices.

thanks Jo Joan, sleek is the word -our clients would be flattered:)

Airbnb is a great income earner and you sound very positive, having just stopped dealing in holiday accommodation which included Airbnb. Very good friends have a newly built smallish two story house which they use the lower level for Airbnb and any family and friends to visit, it can be securely closed off for Airbnb guest. I suggestion to you is to use the front of your house for Airbnb keeping the rear private. Your Airbnb accommodation can be 1 -2 bedroom with kitchenette, we always locked the 2nd bedroom when not required, saved on extra linen and unexpected guests. If you leave the second bedroom open and not included in the rate the guests will always use it, from experience. The kitchenette only needs a bench under the window with a small fridge, MW , sink, and small table and chairs for cold days. Your new master and ensuite next to the new deck, you walk between the robes which have a joining cabinet above when entering the ensuite. The laundry separate with or without exterior access, you could even have the laundry opening through the kitchen wall. The family bathroom has a bath with shower over. A large linen/storage cupboard in the living room, this can also be used to help separate the guests wing from the private. Guests could have the under cover front verandah for Alfresco dining along with a small portable electric BBQ oven.
