Project Overview

The platform is designed to establish immediate authority with high-net-worth residential property owners, heritage restoration clients, and commercial developers while streamlining lead qualification.
Key Features & Architecture
- Interactive Ballpark Cost Calculator: Built a dynamic estimation tool calibrated to Oxfordshire construction rates. Users can configure project classifications (Glass/Rear Extension, Heritage Renovation, Luxury New Build, Commercial Fitout), adjust floor area (
30 m²to450 m²), and toggle specification tiers (Executive Premium, Prime Luxury, Architectural Bespoke) to get an instant itemized budget breakdown across groundwork, interior finishes, site engineering, and contingency. - Before & After Structural Slider: Implemented an interactive visual comparison slider showcasing a Victorian townhouse in Jericho, Oxford, transitioning from groundwork and scaffolding to a completed contemporary glass and limestone pavilion.
- Filterable Architectural Portfolio: Engineered a categorized showcase (Luxury Residential, Heritage & Listed, Commercial Builds, Extensions & Interiors) displaying project budgets, completion years, and blueprint specification views.
- Credibility & Compliance Architecture: Integrated UK Companies House registration data (
Co. No. 16338908), £10M liability insurance badges, JCT contract guarantees, and client endorsements to reinforce trust. - Consultation & Lead Capture Funnel: Designed a GDPR-compliant inquiry form paired with direct WhatsApp integration and interactive Oxford HQ location details to maximize conversion rates.
