Кабана и складское помещение для дома у озера

The lakeside cabana & storage buildings will sit on a lake beach and service a dock/boat lift 30’ away.
The location of the structure is at the base of a rock cliff on a flat beach. A staircase would be centered between the two structures coming down from the upper-level cottage and parking lot. In front of the structure on the beach would be a firepit, small deck, and dock.
We envision two structures-Cabana which would be 8’x8’ and the Storage building being approximately 10’ x 18’ -these both have separate functions.

First is the Cabana which would have a changing area and provides for personal needs/supplies around swimming/beach fun.
Eco toilet, sink & mirror, beverage refrigerator, shelves & cabinets for lotions, towels.
The second is a Storage area that will house various needs for the boat, lake and beach use.
Boat Items: Life jackets, skis, rope, paddle, boat wax & cleaner, fenders
Lake items: Fishing gear, kayak, paddle, fish net, inner tube
Beach items: Pruners, lawn mower, garden hose, hedge trimmer, sprinkler, shovel, rake
Charcoal, gas cans, tool chest, lawn chairs, gas grill, LP tank, cushions
The exterior style would be Craftsman/Adirondack while interior would be rustic.
We will keep the final look in line with the lake house architecture and design elements. This combined utility area sits at the discharge point from hillside stairs.
Design Elements
• Plan to use the structures 6-month year (not during fall/winter)
• Architectural design options are Adirondack, Craftsman
• Prefer to use LP Smart siding and asphalt roofing (like cottage).
• 8’ ceiling height and if needed we could use two levels (outside stairs)
• Time frame=8 months
• Budget=$100K
Outdoor Spaces
• Patio for walk out area at ground level
• Outdoor shower, storage hooks, wood pile storage

We need design, layouts, and specifications for bidding and construction documents.

On the exterior of the Cabana we would like a outdoor shower
On the exterior of the Storage Building, we would like a "2' overhang roof" to shelter stored fire wood
A possibility for design is the option for a roof deck either connecting both roofs (if they were flat) or just one. If necessary, the stairs could be modified for the deck idea.
