Connova. Nice yard. There are many things to consider before creating a new bed. First you need to know what kind of soil you have. As Steve mentioned above, find a good local independent nursery and ply them with questions. Here we have agricultural extension services which will analyze your soil. A knowledgeable nursery person should be able to tell you if you have something comparable. That basic gardening book you're going to get will explain different soil types—sandy, clay, loam, mixed, whatever. That might influence whether you wish to plant in-ground or create raised beds. Soil types and raised beds are things you can research on the Internet. Then location. What is your orientation? Is your porch facing south or north? If you plan to grow basic summer crops, you want full sun exposure. At the very least, good morning sun into mid-day.
There are as many ways to go about gardening as there are gardeners. As you research and talk to people, you'll get a ton of conflicting information. Having a basic philosophy helps sort some of it out:
how do you feel about pesticides, herbicides, organic vs not; supporting insect populations, pollinators and natural wildlife; home composting, etc. Giving thought to these issues will help guide how you go about creating your garden. There is a lot of good information on the Internet, but a whole lot of junk. Many people who have grown one successful crop one year suddenly become "experts" and make a YouTube video. Look for info on sites ending in .org or .edu. or by people who can demonstrate years of experience. One of my guides is that if there are more ads than information on a site, I move on.
I like Charles Dowding's approach so I've given you three links: one a short video about no-dig gardening, another video about starting a new raised bed on grass, and a very long, detailed article about same. He's in the UK which might have a similar climate and growing season to yours. All this should give you plenty to think about. BTW, "no dig" or "no till" is an approach not embraced by all gardeners. Tilling soil has been the norm for millennia, and it's only since soil scientists have uncovered the role of soil micro-organsims that thinking is gradually changing. Your method is your choice. Building up healthy soil can take two or three years, however you go about it.
