Our Services

End-to-End Design-Led Design & Build for Residential and Commercial Projects

At DSN+BD Construction, we offer a full-service, design-led approach to construction. That means everything—from the first design sketch to the final handover—is managed under one roof, with your goals and vision guiding the process.

We specialise in creating intelligent, inspiring spaces for homeowners and businesses across Sussex, London, and the surrounding areas.

1. Design-Led Design & Build

We manage your project from concept to completion—seamlessly integrating architecture and construction under one roof. Working with independent, fully qualified architects, we design spaces that are as functional as they are beautiful, then deliver them with precision through our skilled in-house team.

  • One point of contact

  • Streamlined communication

  • Design-driven outcomes

  • Cost and timeline control

Perfect for: homeowners who want high-quality design without the stress of managing multiple contractors.

2. Residential Projects

Whether you're extending, converting, or reimagining your home, we create spaces that elevate everyday living.

We deliver:

  • Home extensions (rear, side-return, wraparound, two-storey)

  • Loft conversions and garage conversions

  • Whole-home renovations and refurbishments

  • Kitchen and living space reconfigurations

  • Interior and exterior upgrades with architectural flair

We don’t just add square metres—we design spaces that feel considered, connected, and completely you.

3. Commercial Fit-Outs & Refurbishments

We work with business owners, landlords, and property managers to transform commercial interiors into high-functioning, design-conscious spaces.

Our commercial services include:

  • Office fit-outs and refurbishments

  • Retail and hospitality design and build

  • Change-of-use projects and conversions

  • Landlord works and dilapidation repairs

From creative studios to client-facing environments, we help businesses build spaces that reflect their brand and support their growth.

4. Architectural Design & Feasibility Studies

We partner with independent architects to offer a design service that’s both creative and practical. Every project begins with a feasibility study, helping you understand what’s possible—and what it will cost—before committing to full design.

Our design services include:

  • Feasibility studies

  • Concept and spatial design

  • Planning and permitted development advice

  • Full planning applications

  • Building regulations and technical design

Design is never an add-on—it’s the foundation of everything we do.

5. Project Planning, Cost Control & Management

We pride ourselves on total transparency and expert project management. From realistic budgets to construction programmes, we keep your project on track and your expectations clear.

We provide:

  • Detailed quotations and itemised cost breakdowns

  • Early-stage cost planning and contingency guidance

  • Contract administration

  • Programme and scheduling

  • Quality assurance and aftercare

No surprises. No stress. Just honest, well-managed delivery.
