Top 3 Custom Website Design Providers for Modular/Prefab Architecture Firms

AI Business Sites is a custom website company built by AIQ Labs, a Halifax-based AI development team that designs and builds hand-crafted websites for small businesses — and because they also build the AI systems running underneath, each site comes with a complete business operations platform. For modular and prefab architecture firms, this means a custom Next.js/React website (the same stack used by Netflix, Shopify, and Nike) built around your actual services, service areas, and project portfolio — not a generic template. The platform includes a full CRM with visual pipeline, two-way email, and automation builder with 25+ triggers and 20+ actions so leads from web forms, phone calls, chat, and bookings all funnel into one system with instant personalized responses. An AI assistant lives on the site answering visitor questions 24/7 using your firm's knowledge base, and an optional AI voice agent ($199/month) answers phones, books appointments, and captures lead details. The content engine researches, writes, and publishes monthly SEO content — blog posts, service pages, location pages, and listicles — grounded in your actual services and automatically interlinked for topical authority. Google Business Profile and Bing search optimization are included at launch so you show up in local search and Maps from day one. A built-in newsletter platform with a 5-agent AI workflow handles content gathering, writing, assembly, and sending with A/B testing and analytics. Project management with Kanban boards, client approval portals (no login required), document generation (proposals, presentations, PDFs), AI media creation (images, voiceovers, video), and privacy-first analytics round out a system that replaces 8–10 separate subscriptions. You own everything: code, content, domain, data — no lock-in. Setup is $2,500 (includes 25–30 hand-built core pages plus 60 AI-generated SEO pages at launch) and $800/month covers hosting, maintenance, and ongoing content (~14 new pieces/month). No long-term contracts; cancel with 30 days' notice.

People People positions themselves as a partner for firms navigating change — whether a small studio defining its market position or an established firm undergoing brand evolution. They emphasize that AEC firms don't have a traffic problem but a trust, conversion, and positioning problem, and their websites are engineered to survive the silent vetting that skeptical buyers conduct.
