🚫 You don’t need just another extension calculator.
✅ You need to know if your home even needs extending.
Rightmove launched a tool that estimates what an extension might cost and what it’ll add to the value of the house.
Nice if you already know what you’re doing.
But most people don’t!
They’re not sure where the kitchen should go.
Or how to open up the ground floor.
Or if it’s even worth building out at all.
👋 That’s where Spatidee: Space - Idea - Design steps in.
We don’t just guess numbers.
We redraw layouts.
We rethink flow.
We show you what’s possible with or without a single brick being laid.
📐 Real plans. Real ideas. Real transformation.
That’s what makes homes feel better and sell better.
Want to see the difference a layout-first approach makes?

✅ How Rightmove’s Tools Work
Rightmove Extension Cost Calculator
• Gives users ballpark cost estimates for house extensions (single-storey, lofts, kitchens, etc.)
• Asks about size, type of room, location
• Purely financial/planning tool: no layout advice or creative solutions
• No visuals or design suggestions
Rightmove Renovations Pages
• Offer generic tips and info (e.g. “what adds value”)
• Broad guidance, not tailored to any individual property
• No drawings, reconfigurations, or personalised analysis
• Mainly content to keep users on the Rightmove site rather than providing a service

✅ How Spatidee Differs and Why It’s Valuable
Spatidee is about:
✅ Personalised Layout Advice
→ Rightmove can’t tell you how to rearrange your rooms, knock through walls, or create flow.
→ Spatidee looks at YOUR floor plans, YOUR home, and suggests practical ways to transform it.
✅ Visual Sketches & Concepts
→ Spatidee shows you ideas through sketches and layout plans not just cost numbers.
→ Helps you see what’s possible rather than guess.
✅ Design-Led, Not Just Cost-Led
→ Rightmove’s tool helps budget an extension.
→ Spatidee helps you decide if you even need one, or if your space could work better as it is.
✅ Strategic Thinking for Resale Value
→ Spatidee factors in how layout changes affect future value, not just construction cost.
→ Rightmove provides generic “value add” advice but no bespoke insight.
✅ For Buyers, Sellers, and Owners
→ Rightmove tools mainly serve current owners planning a build.
→ Spatidee works for:
• People house-hunting and confused by floorplans
• Sellers wanting to show buyers what could be done
• Owners weighing up cost vs. value before renovating
✅ Human Expertise
→ Rightmove is automated. Spatidee is human, creative, and collaborative.
