Frequently Asked Questions

General

What is a design-led design and build company?
A design-led design and build company brings together high-quality architectural design and expert construction under one roof—with design leading the process. At DSN+BD, fully qualified independent architects develop the creative vision, and our in-house build team delivers it with precision and care. You get beautiful results, fewer compromises, and a smoother experience from start to finish.

How is this different from a standard builder or design and build company?
Most standard builders or design and build firms focus on speed and cost-efficiency, often using in-house draftspeople to keep design simple and repeatable. We’re different: we start with design, not shortcuts. Our architects are fully qualified, creative professionals who design bespoke spaces tailored to you—not templated solutions driven by build constraints.

Project Scope & Services

What types of projects do you specialise in?
We specialise in:

  • New build homes

  • Home extensions and renovations

  • Loft and garage conversions

  • Whole-home transformations

  • Commercial fit-outs and refurbishments

Whether it’s a residential reconfiguration or a complete commercial workspace overhaul, we apply the same design-first thinking and commitment to quality.

Do you offer architectural services in-house?
We work closely with a network of independent, fully qualified architects. This ensures our clients benefit from creative, unbiased design thinking while maintaining full integration with our construction team. It’s the best of both worlds.

Can you help with planning permission and building control?
Yes. We manage the full process—from design development and planning applications to building regulations and compliance. We also handle party wall notices, structural design coordination, and other statutory requirements for both residential and commercial projects.

Costs & Budgeting

How much will my project cost?
It depends on the size, complexity, and level of finish—but we’re always upfront. We begin with a feasibility study to explore your goals and give realistic cost guidance early. Our quotes are fully transparent and include everything—from design and build to VAT and professional fees—so you know the total cost, not just the build price.

How do you manage cost during the project?
Cost control is embedded in our process. We:

  • Involve the build team early during design

  • Offer detailed breakdowns and realistic allowances

  • Fix the price before construction begins

  • Discuss contingency planning up front

This applies whether we’re building your dream kitchen or transforming your commercial space.

Process & Timeline

What does the process look like from start to finish?

  1. Initial consultation – we get to know your goals

  2. Feasibility study – early designs + cost guidance

  3. Architectural design – by our project architect

  4. Planning + approvals – handled by our team

  5. Detailed design + fixed quote

  6. Construction – managed and delivered by us

  7. Handover + aftercare

This process applies across both residential and commercial projects.

How long will my project take?
It depends on the scale, but as a rough guide:

  • Feasibility + Design: 6–8 weeks

  • Planning Approvals: 0-8 weeks

  • Build Phase: 10–24 weeks (depending on size/scope)

We’ll give you a tailored timeline during the feasibility stage, whether you're extending a home or refitting a business premises.

Quality & Aftercare

Who actually builds the project?
Our in-house construction team and trusted specialist subcontractors carry out all the work. We maintain control of quality, coordination, and delivery throughout.

How do you ensure build quality?
We work from detailed architectural drawings and check every stage against agreed specifications. Our site team and project lead perform regular quality inspections, and we never rush a finish. We build as if it were our own—residential or commercial.

Do you offer aftercare or warranties?
Yes. Every project comes with a defects period and responsive aftercare. We also provide documentation, user guides for new systems, and full warranty information for materials and appliances.
