Your Parkeas account works for booking and for hosting. You don't need a second account to list your driveway.
On your guest dashboard, select Switch to Hosting at the top of the page. On a phone, it's in the row at the top, next to Back to site. Once hosting is on, it's in your account menu too.
On other Parkeas pages, such as the home page, Switch to Hosting is in the header on larger screens. On a phone, open the menu and choose Host Dashboard under As a Host.

If your account was set up only for parking, Switch to Hosting opens Start hosting on Parkeas. Select Turn on hosting. You can keep booking parking as usual. Not ready? Select Back to my dashboard.
A guest-only account sees Become a Host in the dashboard account menu instead. It turns hosting on and opens the new listing form straight away.

In the Host Hub, select Switch to Parking at the top of the page or in your account menu. You're back on My parking.
