# Enclos 5.6× faster on phones for its Projects page, without a redesign

Calhoun Design built enclos.com around big project photography and video, and Enclos has been a client for more than ten years. By 2026, a decade of new pages and photos had made the site slow on phones. I went back in and got its Projects page showing 5.6 times faster on a phone in Google PageSpeed Insights, without changing how anything looks.

## What was slowing it down

Ten years of new pages, plugins and project photos had piled up. In PageSpeed Insights on a phone, the Projects page, where people browse the portfolio, took 14.6 seconds to show its main content.

I found four problems and fixed each one without touching the design.

1. **Styles**

   **Before:** More than 270 KB of CSS had to arrive before a page could show anything.

   **After:** The styles for the first screen are written into each page, and the rest load in the background.
2. **Gallery photos**

   **Before:** Project pages loaded a dozen full-size gallery photos at once, including the ones far down the page.

   **After:** Photos load as you scroll toward them.
3. **Image files**

   **Before:** Nearly 1,000 images were heavier than they needed to be, and phones downloaded the same files as desktops.

   **After:** Every image is re-compressed in a modern format, in separate sizes for phones and desktops.
4. **Layout shifts**

   **Before:** Text and buttons jumped around as images arrived.

   **After:** Pages hold still while they load.

Nothing about the design changed, and the Enclos team updates the site the same way it always has.

The same work added an llms.txt file, which tells AI tools what the site covers, and a fallback so every page has a search title, description and share image even when nobody writes one.

## Before and after, on a phone

Largest Contentful Paint is the moment a page’s main photo or headline appears, and it’s one of the numbers Google uses to judge how fast a page feels. These are the Projects page’s numbers in PageSpeed Insights on a phone, before the work and after it.

Seconds until the main content shows

- Before, July 2, 2026: 14.6 s
- After, November 8, 2026: 2.6 s

5.6× faster

## More than ten years with Enclos

The website is one part of the work. With Calhoun Design, I’ve also worked on these for Enclos and its companies.

- **Coalition Glass**

   A sister company. Calhoun designed its logo, then a one-page site, and now a full site its own team keeps up to date.

   [How Coalition Glass went from one page to a full site](https://tintcoding.com/work/coalition-glass/) [coalitionglass.com](https://coalitionglass.com/)
- **ETS**

   Acquired by Enclos. I rebuilt its aging site from the ground up, with a project portfolio and a history timeline full of video.

   [How the new ETS site got 12× faster](https://tintcoding.com/work/ets/) [ets-na.com](https://ets-na.com/)
- **The Enclos Companies site**

   One site that shows how the brands fit together.
- **A proposal builder**

   Sales uses it to put together proposals that match the brand.
- **An intranet**

   Internal news and tools for Enclos’s own staff.
