Why The Annex

Not every lake house feels like this one.

The Annex isn't a rental you pass through on the way to something else. It's the destination — a thoughtfully designed cottage where the morning coffee tastes better because the lake is right there, and the evening quiet feels earned.

Located on a quiet stretch of Port Austin Road in Caseville, we're close enough to walk to the marina, the local eateries, and the public boat launch — but far enough from the noise to feel entirely your own.

Bright, minimalist living space in The Annex with large windows overlooking the water

The Space

Designed for the way you actually vacation

Open living, a well-equipped kitchen, comfortable sleeping for up to six, and large windows that frame the lake the way a painting would — only better.

King bed with white linens and lake view through large window

Sleeps six

A king master with lake views, a second bedroom with twins, and a sofa bed in the living area — comfortable for a small family or a group of friends.

Modern kitchen with open shelving and natural light

Full kitchen

Everything you need to cook a proper meal — from a well-stocked pantry to a coffee maker that actually makes good coffee. Breakfast by the water is the best kind.

Wooden deck overlooking Lake St. Clair at sunset

Private deck

Step outside and be at the water's edge. The deck faces south over Lake St. Clair — golden hour here is something you'll remember.

Clean, spa-like bathroom with natural stone accents

Modern bath

A shower with good water pressure, plush towels, and the kind of quiet you only get when you're not sharing a hallway with anyone else.

Open-plan living area with comfortable seating and bookshelves

Open living

A spacious great room where the kitchen, dining, and sitting areas flow together — built for lingering dinners and lazy mornings with the windows open.

Dedicated parking area next to the cottage with mature trees

Easy access

Free parking right next to the cottage. No stairs, no narrow lanes — just pull up, unload, and step inside.
