Multi-page website of the window installation company

A well-known Kiev company, for which a one-page site was previously created four years ago, addressed a request to create a multi-page site.
For this purpose, the original template was created on WordPress and Bootstrap. The buyer gave the tree categories and approximate design (his competitor). As a SEO article network was planned for each category of windows, a multi-level menu was implemented. The site is transferred for filling.
