I believe it was Variety that broke the news.
The first is “Lockwood & Co,” a supernatural action-adventure detective series, based on the novels by Jonathan Stroud. The series will be helmed and executive produced by Cornish.
There's more but similar here.
The author's website has this to say (you might have to scroll down).
Of the announcement, Jonathan says "I’m thrilled that Lockwood & Co. is being developed for Netflix as one of Complete Fiction’s first projects. I’ve long been a fan of the amazing work that these guys have done, and I know their vision for the series will be breathtaking. I can’t wait to team up with them to create a haunted London full of marauding spectres!"
