Understanding the Design-Build Process: A Step-by-Step Guide

If you’re planning a home extension, renovation, or even a new build, you’ve probably come across the term design and build. It’s a project delivery method that’s growing in popularity across the UK – and for good reason.

At STAAC, we’ve been offering this all-in-one service for years, helping clients enjoy a smoother, faster, and more cost-effective building experience. But how does it actually work? What should you expect?

Here’s a step-by-step look at the design-build process, so you can understand how it simplifies your project from start to finish.

Step 1: Discovery & Brief

It all begins with a conversation. We take the time to learn about your goals, your budget, and how you want to use your space. Whether it’s a rear extension, a loft conversion, or a new home, this stage is all about building a clear picture of what you need.

What happens:

• Site visit (if needed) or virtual consultation
• Discussion of your needs, vision, and priorities
• Budget guidance and realistic advice
• Planning considerations flagged early

Benefit: You’re talking to one team from the start – no bouncing between designers and builders.

Step 2: Design Development

Our architectural team creates a concept that fits your brief, lifestyle, and budget. Since our construction team is involved early, we make sure every design detail is practical to build and cost-effective.

What’s included:

• Floorplans and 3D visuals (if requested)
• Pre-application advice or planning submission
• Adjustments based on feedback
• Coordination with consultants (e.g. structural engineer)

Benefit: The design is grounded in real build knowledge – no costly surprises down the line.

Step 3: Detailed Quote & Agreement

Once the design is agreed, we move into detailed costing. This isn’t a vague estimate — it’s a comprehensive quote based on your actual design and the real costs to build it.

You’ll get:

• Full construction quote
• Clear timeline and payment plan
• Fixed-price contract with agreed scope

Benefit: You can save up to 8% compared to hiring an architect and tendering separately.

Step 4: Construction Begins

With planning approvals and documents in place, we move into the construction phase. Because we’ve been part of the design journey, there’s no learning curve — our team hits the ground running.

We manage:

• Site set-up and project scheduling
• Building control coordination
• Regular updates and progress checks
• Quality assurance at every stage

Benefit: Less risk, fewer delays, and a faster overall build time.

Step 5: Final Handover

When construction is complete, we carry out final inspections, walk you through the finished space, and ensure you’re 100% happy before we hand over the keys.

You’ll receive:

• Completion certificates (where applicable)
• Final quality checks
• Ongoing support if needed

Benefit: One accountable team delivering your project, from start to finish.

Why Choose the Design-Build Approach?

Design-build works so well because it’s efficient, collaborative, and built around your needs. It reduces stress, gives you more control, and often costs less than managing separate designers and builders.

At STAAC, our team combines creative design with practical construction knowledge — all under one roof. We handle the entire process so you don’t have to juggle different professionals or worry about the small stuff.

Choose STAAC for your design and build project, and you could save up to 8% on overall costs – while finishing faster and with less hassle.
