I agree with @topelovely.
But I’d do something else first. I’d manage to get access to the Google Analytics account with ID UA-331093-1.
Within Analytics you can see the most clicked links on the current website. So you can figure out what information is most relevant and give that a prominent position in your new design. Also, you can see if visitors are mostly desktop users or already mobile (tablet,phone etc.). You can be sure the latter will be more prominent the coming years. So you might want to think “content first” and if you’re not convinced, here’s another argument. Example: the most important museum in The Netherlands made new website: “tablet first”, and they’ve got over 7 million visitors yearly on their website.
If it’s not possible to get into Analytics and the client doesn’t know what’s most important: keep it a bit similar with the KW-company, you might want to use a similar design as they have
[on their homepage
]. Meaning: fancy slider, features properties, clean menu, some info boxes and a footer. Strip the irrelevant links in the footer, that’s a no-go for SEO since 2013.
And, as mentioned, give Webflow a decent try.
