If you're serious about learning a new instrument, then an appropriate practice space is an absolute must. But what makes for the perfect practice space? Definitely having a big enough area and all the equipment you'll need to play. But it's more than that, as there are often details that can be overlooked that are definitely essential.
While it's unlikely you'll be able to create the perfect space, there are things you should look out for in order to maximize your space. Things like power outlets, temperature control and soundproofing (for you and your neighbors!) are all things that may not be top of mind, but they definitely make a huge differencein terms of comfort and efficiency for your practices. There is no one-space-fits-all though, so prioritize your needs by how much you value those details and work to get as many as possible.
You'll also want to make sure you have all the right equipment. Having a tuner, music stands, instrument maintenance accessories, notebooks and pencils, a metronome, and a recording device to mark your progress, will all enhance what you're capable of, allowing you to focus on different aspects of your play and analyze them later. Don’t forget comfortable seating too! If you're going to be practicing a lot, this is something that should be at the top of every list.
The ultimate goal is to set up a practice area and leave it set up. Having it always ready will encourage you to practice more and will give you more time to play. This isn't always possible though, so do yourself a huge favor and organize your equipment in containers for easy access. And because you'll have everything you need in your "portable practice kit" you can even take your practices on the road if you want to jam with other musicians.
On top of that, there are a few other considerations you should keep in mind:
