LT Architecture
Joomla template for design-and-build home builders: one house drawn going up in eight stages, homes on site, build types with costs per m² and a build enquiry form.
The Joomla demo is coming. The preview shows the same design on its WordPress version.
The Joomla version of this design is being rebuilt on the stack below. Until it is released, the download is the current version of LT Architecture for Joomla.
Key features
LT Architecture explains a build as a row of eight drawings of the same house, from bare block to handover, each with its weeks and the sum due at the end of that stage. Projects show the stage they have reached, and pages cover single and two storey homes, sloping blocks, extensions, knockdown rebuilds and the team.
- A house built in eight drawingsThe home page lines up eight elevations on one ground line, with what is new at each stage picked out and the weeks beside it.
- Homes at their current stageEach project shows the drawing for its stage, the build week, size and location, plus a board of homes on site.
- Build types and costsSingle storey, two storey, sloping blocks, extensions and knockdown rebuilds, with example costs per m² and what a fixed quote covers.
- Quickstart or template packageStart from a full copy of the demo site (the quickstart package of the Pro editions, restored with Akeeba Kickstart and Akeeba's restoration script in the browser) or add the template to a Joomla site you already run.
- Fonts that ship with itChanga and Martel are bundled with the template, so pages make no requests to Google Fonts.
- Change it without codeColours, fonts, logo, header and footer are Helix Ultimate template options; page sections are edited in SP Page Builder Lite.

Two ways to install

Best for a new site: upload it to an empty folder and restore it with Akeeba Kickstart and Akeeba's restoration script in the browser, then replace the sample texts and images.
- Template package (all editions)Only the template, and the only package in Free. Install it in System > Install > Extensions on a Joomla site you already have, then build your pages; the demo layout is not imported.
What an AI assistant can do for a Joomla site
No AI writes into your Joomla site by itself. These are the honest options today; you stay in control of every change.
- AI help in ticket support Available now with Pro Open a ticket and you get an instant AI-drafted answer; a person from our team follows up. Ticket support
- Texts for your pages Works with any AI assistant Ask an assistant such as Claude or ChatGPT to draft your page texts in your own words, then paste them into the SP Page Builder text editor and your Joomla articles.
- Small design changes Works with any AI assistant Describe the change and ask for CSS; paste it into Helix Ultimate's Custom Code tab and check the page before you save.
- AI kit WordPress version only The kit that lets an assistant edit pages safely (instructions, ready prompts, a checked import tool) exists for our WordPress themes only. Nothing in a Joomla site is changed by AI unless you paste it in. See the WordPress version

Questions
Is it only for home builders?
It also suits residential architects, renovation firms and extension specialists who explain a project stage by stage.
Do I need SP Page Builder Pro?
No. The pages use the free SP Page Builder Lite, with Convert Forms Free for the contact form; Helix Ultimate is free too.
Quickstart or template package: which one do I need?
Take the quickstart package for a new site that should look like the demo. Take the template package to restyle a Joomla site you already have; your content stays and the demo pages are not added.
Why does the preview open a WordPress site?
The Joomla demo of this design is not online yet. The Joomla version uses the same design and pages, so the preview shows what you get; the Joomla demo will replace it.
What is the difference between Free and Pro?
Free is the template package with the footer credit. Pro adds the quickstart package (a full copy of the demo), credit removal and ticket support: Pro Standard for one website with a year of updates, Pro Unlimited for unlimited websites with lifetime updates.
What if it does not work for me?
If a Pro product has a problem we cannot fix, open a ticket within 30 days of your order and we refund it in full.
