Structural Alterations in Sunderland.

Design N Build Construction Company is a leading construction company delivering structural alterations across Sunderland and the wider East Midlands. From our base at 22 Franklin Drive, West Bridgford, we mobilise survey teams, design engineers, quantity surveyors and site managers to Sunderland projects within 48 hours of enquiry — backed by a fixed-price BOQ delivered within 7–10 working days.

Whether you're a commercial developer, public-sector client, healthcare trust, school or private homeowner in Sunderland, our integrated design and construction team owns every stage of the build. We handle planning applications with the local authority, discharge of pre-commencement conditions, Building Control sign-off, party wall awards and statutory undertaker liaison — so you deal with one accountable contractor, not five competing consultants.

Every structural alterations project in Sunderland is run under either NEC4 or JCT contracts with weekly cost and programme reporting, monthly board-ready dashboards, and a live risk register your finance and operations teams can audit at any point. We are CHAS, Constructionline and ISO 9001 aligned, with public-liability cover sized for major commercial works and full CDM 2015 Principal Designer / Principal Contractor capability in-house.

Local knowledge matters. We have delivered schemes across Rushcliffe, Nottingham City, Broxtowe, Gedling, Ashfield, Erewash and Derby City — so we know each authority's local plan, validation checklist, S278/S38 standards, SuDS requirements and ecology constraints. That intel translates directly into faster planning approvals, fewer surprises on site, and a project programme you can actually rely on.
