Diamond Buildings & Energy

The question

The client is starting two companies at once. Diamond Buildings installs aluminium verandas, carports, door canopies, windows, doors and roller shutters. Diamond Energy does air conditioning, solar panels, home batteries and charging points.

The same job twice: an extensive catalogue that only existed as a supplier PDF, full of other people's prices and logos. It had to go online without turning into a price list, and it had to feel like one brand. On top of that he works in Belgium and the Netherlands, and wants to reach people who do not speak Dutch.

What I did

One design for both: a dark background, gold as the accent, a serif that is allowed to be large. Energy is not a copy but the same foundation, with the same structure and style and different content. That is why the second site took days instead of weeks.

The catalogue became data instead of a PDF. At Buildings you first pick the type of cover, then the model, and a configurator shows colour and roofing together. At Energy you filter by brand, by type and by the floor area of your room, and a comparison table puts the models side by side.

There are deliberately no prices: he comes to measure first. There was hardly any imagery, so product photos were cut out of the PDFs and cleaned up, models without a photo got their own line drawing in gold on dark, and the mood images were made.

Both in six languages, with Arabic running right to left.

What it delivered

516 pages live between them: 234 for Buildings and 282 for Energy, each with its own title, description and structured data in all six languages.

On a phone Buildings went from 70 to 93 in Lighthouse, and from 4.3 to 1.8 seconds for the largest image. Accessibility, SEO and best practices sit at 100.

The client has one point of contact for two brands, and a new model is a line in the data instead of a new page.
