Your going to need a building permit so you might as well get an arhcitect involed now. We have zero way of knowing if your current home can even be added on to. Whether there is room zoning wise for an addition, etc., etc..

A saltwater pool will not smell like chlorine but an enclosed walkway from house to pool addition would be nice.

A glass garage door would be fun!

Thats VERY expensive project if you propose to keep it warm enough for plants and people during a MI winter. Expensive to build too.

Follow ‘the guest house at six lights’ on Facebook. Maine man building enclosed pool and guest house on the downeast coast- no more extreme wheather than that.

Hi! If you're from Europe, I strongly recommend reaching out to a construction platform that collaborates with specialized companies who can advise you on this. Here you can find a group of platforms where you can choose based on your location and send them a message. I hope this will be helpful to you.

"climate is in Michigan. thanks"

You need to get a pro in your site to answer all those questions and then some. First it will need to be quite large and interesting to heat all winter to be able to enjoy it. when you say addition do you mean attached to the house or more like a greenhouse with a walkway for access.

Sorry for not seing. Thank you.

Go talk to your local building inspector/ordinance officer. Bring your house info, including property space. And a basic plan on what you want to build. They can tell you if you are zoned, if there are things like frontage required for footage, building limitations, that sort of thing. If they say, yeah, sounds like you could do it... then go find pros to help you out.

I live in an area with some building limitations, and frontage for building, and acerage for footage. Depending on where you live, your rules may vary.

A dehumidification system, such as DesertAire, will be needed to prevent humidity in whatever space or location you choose. I tell all my clients this when we are designing/building an indoor pool.

Depending on your current HVAC system, this system can be adapted.

If this system is not in place, everything will sweat and eventually rot. Mold can be an issue as well.

I strongly recommend an automatic cover as it retains any moisture from the pool. With no cover, the dehumidification system will work much harder.

Consider an AOP system instead of a salt system. Generally indoor pools are not very big and even the smallest salt systems may be too big and difficult to dose based on the pool volume.

The AOP systems utilize UV and Ozone as a way to sanitize. This allows you to maintain low chlorine levels and still keep a clean pool.

Mechanical's location is important especially a gas fired pool heater. Proper venting is paramount. Most of the pool heaters are fan assisted venting and cannot be combined with say a common vent for a hot water heater or a furnace. Separate venting and fresh air intake are required, and it can be tricky on how to accomplish this. An HVAC contractor or a plumber will be versed in this aspect.

Decking should be pitched back towards the pool to capture as much surface water as possible.

cool

walkway, with a standalone unit for heat and a pool heater if I have the floor done with an extra barrier. My biggest concern is pool splash/overflow and their a drain will be needed and should I tie it into the roof ( which I feel like is a yes answer). Thank you all for the suggestions and advice as I work through this idea. I am close to my savings goal for what I anticipate the project to cost so I’m hoping to start talking to experts about this in January 26!!!!

My BIL has a sun water heater for the pool that keeps the pool a nice temperature in the Summer. The water is recirculated on the roof and the sun heats it up. The only energy needed is for the water pump.
