The Future of Design & Build
A Smarter Way to Build
If you’ve spoken to builders or designers before, you’ve probably heard the same stories: projects going over budget, long delays, and drawings that look great on paper but don’t work in real life. Too often, this happens because designers and builders work separately, budgets are only checked at the very end, and communication breaks down along the way.
Design & Build Connect helps London homeowners plan and deliver extensions, basements, loft conversions, flat conversions, new builds and renovations with clarity and control, no vague quotes, drifting scope, and stress.
Design & Build
One joined-up route from feasibility to finished build. This option suits homeowners who want a structured, end-to-end service – with fewer gaps between design and delivery, and a clear process that stays tied to feasibility and budget reality.
Architectural Design
Architectural design isn’t just about what’s possible – it’s about what’s feasible, policy-aware, and buildable for your budget.
Interior Design
Interiors are where projects win or lose value. We help you make confident choices that suit your lifestyle, protect resale value, and keep spending focused.
Construction & Project Management
By involving our builders from the very start, we provide accurate estimates and ensure projects remain on budget and on schedule, avoiding the costly delays or restarts that often occur after planning approval.
What we do
We guide your project from early feasibility through design, approvals, and build delivery – acting as the link between design and construction so the plan you agree to is realistic, buildable, and budget-aware.
Every project is different, so we build the right team around your home: architectural input, interior design support, technical specialists and trusted builders – all coordinated through one clear process.

Because every great project starts with trust
Amine Ait M'Hand
I founded Design and Build Connect to bring clarity, creativity, and cost control to residential construction projects in London. Having seen many projects fail due to the disconnect between designers and builders, I realised that budgets often spin out of control when these two worlds don’t speak the same language.
With over a decade of experience in design and project delivery—including senior roles at Extension Architecture and Modern Luxury Design—I guide my clients from the earliest sketches through to final completion. My approach is rooted in practicality and transparency; I provide the smart design and rigorous planning necessary to ensure every detail is considered and every project stays on budget.
My mission is to help you create a beautifully designed home through a thoughtful, transparent process that protects your investment and makes the journey as enjoyable as the result.
"Trust is built when promises, plans, and budgets are treated with the same discipline and delivered exactly as agreed."

Some of Our Projects
Extension and Loft in Hampstead
