About the client

PTH Green works across solar, biogas, wastewater treatment, and electrical systems — technical, engineering-led work where credibility and clarity about capability matter as much as design.

The brief

A technical engineering business needs its website to do something specific: let a prospective client — often another company evaluating a contractor — quickly understand which systems they work with and see evidence of completed projects, without wading through jargon or a single vague "services" page.

What we built

  • Designed and developed the complete website from the ground up
  • Created service and project showcases for solar, biogas, wastewater, and electrical systems, each with its own clear space
  • Built a responsive, bilingual (Thai/English) experience for both domestic and technical/international audiences
  • Added SEO-focused content and lead-generation paths so each service area can be found on its own terms in search

Tech & approach

Full-stack, end to end — design, front end, content structure, and SEO — following the same process as every r1dx project, outlined in our website process, from brief to launch. For a multi-service technical business, separating each system type into its own clear section made the biggest difference, the same principle applied on the Phatthalung Holding site.

The result A clean-energy engineering company that previously had no single place to show the range of systems it works on now has dedicated, findable pages for solar, biogas, wastewater, and electrical work — with a clear path to enquire about any of them.

Frequently asked questions

What makes a website different for a technical engineering business?

It needs to separate distinct technical service areas clearly — lumping solar, biogas, wastewater, and electrical work into one vague page makes it harder for a prospect to find what they actually need.

Is PTH Green part of the same group as Phatthalung Holding?

Phatthalung Holding's own site describes its group as spanning clean-energy, construction, security, and accounting businesses — see the Phatthalung Holding case study for that group's own site.
