To find the previous businesses at that address, contact the City and ask for business license history at that address. Most cities require a business license for every business that wants to operate in a city.
To find the previous construction activity at that location, contact the City (or County if it's unincorporated) and ask for Planning and Building permits at that location. Some sort of permit is always needed when something is being built, so there should be records on it.
Typically, City/County websites have a permit record database online under their Building/Planning/Community Development department. You can usually use those to search up permits for an address. To see actual plans, you would need to contact the City.
For business licenses, that information isn't normally available online but should be public record and can be accessed by contacting the City.
I love the inclusion of the Rwandan proverb translated into Gallifreyan. It's a really cool way to portray homage to the Doctor's character while also including non-Western influences.
As to the design of the screwdriver itself, I quite miss the old cylindrical design. I'm sure it'll be fine in action though.
