Architecture Sales at Extension Architecture & Interiors, Wandsworth

About us
We are a London architecture and design practice for homeowners. We design house extensions, loft conversions, new builds and interiors. We take each project from first idea through planning permission, tendering and project management. Our in-house teams cover planning, interiors, kitchens and project management, and we have an office showroom where clients can see what we offer.

The role
You’ll be the first point of contact for new clients and the person who turns an enquiry into an instructed project. This is not a call-centre sales job. You’ll understand each client’s home, budget and goals, do early planning research, and show them how we can deliver their project. If you enjoy property, design and building relationships, this role is for you.

Key responsibilities

• Handle new enquiries and run 30-minute discovery meetings with homeowners, online and in the office.
• Understand each client’s brief, must-haves, nice-to-haves, budget and timeline.
• Research each site before the meeting: planning history, local precedents, conservation areas, Article 4, flood risk and other constraints, using tools like Searchland and council planning portals.
• Prepare clear fee proposals and send them within 24–48 hours of the meeting.
• Follow up proactively by phone, WhatsApp and email until clients instruct us.
• Book measured surveys and hand projects over smoothly to the planning team, with full notes, research and budget recorded in our systems (Notion, Asana).
• Invite clients into the office and introduce our later services: tender, project management, interiors and kitchens.
• Keep the CRM and pipeline accurate, and report on conversions and targets.
• Represent the company professionally and give clients an excellent experience from the first call.

What we’re looking for

• Experience in sales, business development or client-facing work, ideally in architecture, property, construction, interiors or home improvement.
• A good understanding of UK residential planning, or a strong interest in learning it.
• Excellent spoken and written English, and confidence speaking with homeowners.
• Organised and target-driven, with strong follow-up habits.
• Comfortable with tech, such as CRMs, Google Workspace and AI tools like Claude.
• An architecture or design background is a strong plus.
