What it is

Nordhaus is a storefront theme for furniture, lighting, textiles and home decor stores and for home marketplaces with maker shops, on CS-Cart and Multi-Vendor.

Four styles repaint the room itself: Linen (warm plaster and moss), Walnut (dark walnut in a framed mat), Fjord (cool grey-blue and pine) and Terrazzo (blush room with coral and pistachio).

Four styles, one theme

Each style changes the ground, bands, type weight and card treatment, not only the accent colour. Open any of them in the live demo.

Built for selling

Nordhaus sells the room, not only the piece:

  • Room scenes with a room total and one button for the whole room
  • Every product shown at scale on the same floor line
  • Texture swatches, material library and sample box link
  • Lead time and delivery window on cards and product pages
  • Will-it-fit drawings and a doorway check against returns
  • Sale ribbon and countdowns only for real promotion end dates
  • Text contrast of at least 4.5:1 in every style

How it works

Install the package in Add-ons: it adds the Nordhaus theme without touching your storefront. Activate Nordhaus in Website, Themes and pick a style. The next admin page adds the demo catalogue, so every homepage section is filled at once; replace it step by step.

Rooms are top-level categories. Materials, dimensions and lead times are product features. Room scenes, ribbons and sections are Block Manager blocks.

Features

  • Room bar with mega panels: product types, a room tile and the room's bestseller
  • Shoppable room scenes in tabs with numbered hotspots, In this room, room total and Add the room to bag
  • Built-in room illustrations in the colours of each style, or your own room photo
  • 4:3 wall-and-floor wells for every product image
  • Cards with material and dimensions, texture swatches, lead time, from price and monthly price
  • Shop by room tiles, finds under a price, shop by style chips and a material library with samples
  • Spotlight with dimension lines and a services band
  • Horizontal filter bar with dropdown panels and a Seen in a room tile on category pages
  • Product page with texture tiles for fabrics and finishes, delivery window and a will-it-fit check
  • Multi-Vendor: maker shop line on cards
  • Cart side panel, sticky header, floating tab bar and sticky buy bar on phones
  • Installs with full demo content: every section and demo products are ready after activation
  • Four styles: Linen, Walnut, Fjord and Terrazzo
  • Child of Responsive: add-on hooks keep working
  • CS-Cart and Multi-Vendor 4.17.2 to 4.21.x
