Facciata per spa domestica e spazio di intrattenimento

We have floor plans for a home spa annex that will be a stand-alone building in our backyard. It includes an outdoor kitchen, a Finnish sauna, a full bathroom, and an Endless Pool in an all-seasons pool enclosure. We need a design for a front elevation that includes choosing exterior wall materials and color suggestions (keep in mind color reflected into our home), roof design, and covered entry design.

Additional info:
1. The back door of the house is about 25 feet from the spa entrance of the building. (Picture taken of back of house standing in door of the spa entrance.) There is another door on the west end of the house that will be 10 feet closer to the outdoor kitchen space.
2. Interior ceiling height will be 9 foot.
3. The openings in the kitchen area will have Phantom retractable patio screens and will likely open all the way to the ground (no pony wall) on the front (south). West and north walls will have the pony wall. Screens will be dual-roller (vinyl & insect), recessed mount into columns.
4. The kitchen door will be a Phantom door screen with a Phantom vinyl patio screen behind it.
5. We are not asking for landscape design, but for information purposes, between the house and spa we will have citrus trees and a small water feature of some kind.
6. Windows will be Simonton StormBreakerPlus white vinyl. In the pool enclosure, the window sizes and placement in relation to wall segments may be adjusted for aesthetics, but the awning portion (upper) cannot exceed 5 feet wide and 3 feet high. The window below each awning window is a fixed picture window. Note: We do not want a solid wall of ganged windows.

1. We want it to have a “spa” aesthetic – a destination, not simply an extension of the house. Something inviting.
2. We don't have a particular style in mind, but not rustic “hunting lodge” heavy beams and such. Something refined, but not overly ornate. A little whimsy would be nice.
3. The spa entrance should be the main entrance/central focus. We intend to have a custom etched glass panel in the door with a “Hummingbird Spa” design.
4. The entry to the kitchen and the entry to the spa may share a porch, or not - goal is to have the doorway to the spa have weather protection (less concerned about the kitchen/entertaining space, but feel free to protect it as well).
5. We are taxed for impermeable area, so don’t get too expansive.

1. Exterior wall material can be anything but stucco. Maybe lower half some type of stone/brick, Hardie siding above? All stone on part? All siding? We're open.
2. Interior will be light & bright - see inspirational pictures for the tiles we have selected, exterior should harmonize with interior.
3. The roof may be gabled or shed (high side front). We are considering a metal roof to allow rainwater collection.
4. Apart from the porch/entrance exterior to the building, do not change the footprint of the structure.
5. Avoid rustic, “hunting lodge” heavy beams and dark look.
