Our Design & Build Process: How DSN+BD Delivers Seamless Home Projects

At DSN+BD Construction, we specialise in design-led design and build for domestic extensions and renovations. That means we manage your project from the very first idea to the final handover—with design, construction, and client experience working seamlessly together.

We believe that the journey should be as rewarding as the result. Here’s what you can expect when you work with us.

1. Initial Consultation – Let's Talk About You

Every project starts with a conversation.

We take time to get to know you—how you live, what’s not working, what you’re dreaming of, and how your space needs to evolve.

✔️ We’ll visit your home
✔️ Discuss your needs, budget, and timeline
✔️ Offer early-stage ideas and insights
✔️ Explain how our design-led process works

This is your chance to ask questions and get a feel for how we work. There’s no pressure—just a genuine, collaborative start.

2. Design Brief + Feasibility

Once you decide to move forward, we’ll help you shape your vision into a clear design brief. This includes:

• Your wish list and must-haves

• Practical constraints (e.g. planning, access, neighbours)

• Budget parameters

• Key project drivers—space, light, style, energy, storage, etc.

From here, we carry out a measured survey of your property and begin feasibility work to test what’s possible under planning or permitted development rules.

3. Architectural Design

Here’s where the creativity begins.

We pair you with one of our trusted independent, fully qualified architects who leads the design process in close collaboration with you and our construction team.

You’ll receive:

• Concept designs and layout options

• 3D visualisations (where appropriate)

• Expert guidance on materials, finishes, and flow

• Practical input from our builders to ensure designs are buildable and budget-aligned

This is a truly collaborative stage where your ideas come to life—and our experience helps refine and elevate them.

4. Planning + Permissions

Once you’re happy with the design, we manage the process of securing permissions, including:

• Planning applications (or lawful development certificates)

• Building control sign-off

• Party wall notices (if required)

• Any specialist reports needed (e.g. structural, drainage, energy)

We handle all the technical submissions so you don’t have to.

5. Detailed Design + Final Pricing

With approvals in place, we move into the technical and pre-construction phase, where we:

• Finalise construction drawings and structural details

• Specify finishes, fixtures, fittings, and systems

• Review and confirm your budget based on the fully detailed design

• Create a build programme with key milestones

Because our construction team has been involved since early design, there are no surprises—just clarity and confidence.

6. Construction

Now it’s time to build.

Our expert site team takes over and manages the project day to day. You’ll have a dedicated project lead keeping everything running smoothly, and we’ll keep you updated throughout.

During the build, we:

• Set up and secure the site

• Coordinate all trades and deliveries

• Maintain safety, tidiness, and respect for your home and neighbours

• Carry out regular quality checks and sign-offs

• Keep disruption to a minimum

We pride ourselves on being professional, polite, and proactive. We treat your home like it’s our own.

7. Handover + Aftercare

Once construction is complete, we’ll walk you through your finished space to ensure everything’s perfect.

• You’ll receive a full handover pack

• We’ll explain how to operate any new systems

• We include a defects period and responsive aftercare to give you total peace of mind

We’re not the kind of company that disappears once the last coat of paint goes on. We’re here for the long term.

Why It Works

Our process is simple—but powerful. It combines:

✅ True architectural creativity
✅ Build expertise from day one
✅ Clear communication and responsibility
✅ A client-first approach throughout

No juggling multiple consultants. No breakdowns in communication. No corners cut.

Just great design, well-built—and a journey you’ll actually enjoy.
