01The brief

Prime agencies win on relationships and reputation but lose online to portal brands and faceless chains. Harlow & Stone wanted to read as the trusted, well-connected adviser the best streets recommend — while still capturing the after-hours enquiry, qualifying the buyer, and securing viewing appointments and reservation fees without a single phone call.

02What we built
  • 12-page marketing site — sales, lettings, sold prices, neighbourhoods, fees, results, about, guides, blog.
  • Listings showcase with saved searches + map view, plus instant valuation and viewing-request forms on every property.
  • Viewing scheduler + Stripe — reservation fees, holding deposits and CRM-sent pay-links for marketing packages.
  • 4 free tools — instant valuation estimator, stamp-duty calculator, mortgage affordability calculator, area comparison tool.
  • 24/7 AI property assistant trained on the agency's live stock, fees and viewing availability.

  • 12-module admin CRM — lead pipeline, vendors, applicants, listings, viewings, offers, invoicing, messaging, automations, content, reviews, reports.

  • Hyperlocal + AI-search pages — a page for every service in every postcode, structured to rank on Google and be cited by ChatGPT and Perplexity.
The design — “Prime editorial

Senior and reassuring: warm stone paper, deep charcoal ink and a single hand-set brass accent, large serif headlines over hairline rules. The look of an agency the best addresses already trust. Full light + dark.
