A holistic partner, not another agency

Theo on site, shooting a built environment project DIGITAL FIRST · SINCE 2010

Great marketing isn't about shouting louder. It's about communicating better: showing what makes your business different, and building systems that turn that story into results.

Today we are a digital-first growth studio. Web design, SEO, AI search and paid media do the heavy lifting. Our roots behind the lens mean we also shoot, film and tour the work, and that we genuinely understand how the built environment operates.

Design, build, grow and showcase, under one roof, so your marketing pulls in one direction instead of ten.

07 / FAQ

Questions we get asked

Straight answers on how we work, who we work with, and what digital-first marketing for the built environment actually looks like.

What does Cornerstone Group do?

Cornerstone is a digital-first marketing agency for the built environment. We build high-performance websites and run SEO, AI SEO, Google Ads and paid social, email, digital PR and conversion optimisation for construction, manufacturing and design brands, and we shoot the photography, video and 360 tours that show the work off.

Which industries do you work with?

We work exclusively with the built environment: construction, building materials, architectural materials, manufacturing, building services, interior design, fit out, furniture, and energy and sustainability brands.

What is AI SEO, and why does it matter?

AI SEO, also called generative engine optimisation, is the work of getting your brand understood and cited by AI answers like ChatGPT, Google's AI Overviews and Perplexity. As more people get answers straight from AI instead of clicking search results, being part of those answers is becoming as important as ranking on Google.

Do you tie clients into long contracts?

No. We work on a strict 30 day rolling agreement. There are no long lock-ins, so we have to earn our keep every month.

Where is Cornerstone based?

We are based at 86-90 Paul St, London EC2A 4NE, and work with built environment brands across the United Kingdom.
