Scaling brands in
the built environment
High-performance websites, SEO and AI search, and paid media that grow construction, manufacturing and design brands. Digital first, built for the sector.
Brands we’ve helped build
A holistic partner, not another agency
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.

Where we move the needle
Creative gets you noticed. These are the services that grow the pipeline, and where the level we work at really shows.
Web Design
Websites that win the work
Your website is your hardest-working salesperson. We design and build sites that load in a blink, read clearly on a phone on site, rank on Google and turn specifiers into enquiries. The one you are reading right now is one of ours.
SEO + AI SEO
Found first, and in the AI answers
Search is where the buying starts, and it is changing fast. We get you ranking on Google and cited in AI answers like ChatGPT and Google's AI Overviews, so you are the brand that gets recommended. For Terrazzo Tiles, that meant a 315% lift in organic traffic.

8 reasons why people decide to work with us
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 and Meta ads, 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.
