Request an estimateCall John · 07891 214075 Company story ## A company builton a simple principle Weir Construction Group began over twenty-five years ago with a simple principle: do excellent work, charge fair prices, and treat every client’s home as if it were our own. John founded the company after years working for larger firms where he saw too many shortcuts, too many excuses, and too many homeowners left disappointed by builders who over-promised and under-delivered. Based on Salisbury Avenue in Chesterfield, we serve homeowners, architects and businesses across Derbyshire, the Peak District and into South Sheffield. Our team of directly employed tradespeople, bricklayers, joiners, plasterers, electricians and plumbers, work together on every project, which is why our detailing is consistent from one build to the next. Our specialisms are architect-designed homes, luxury new builds, Passive House and low-energy construction, barn conversions and full project management. We also carry out extensions, structural alterations, refurbishments and commercial projects including shop fit-outs and pub refurbishments. Whatever the contract value, John personally manages the project. What that means for you is fewer unknowns. A fixed itemised quote instead of a single headline figure, one person accountable for the programme, certified electrical and gas work rather than whoever happened to be available, and a building that performs the way the drawings said it would. Over 150 completed projects later, our reputation has been built entirely on word-of-mouth referrals and repeat business, including being entrusted with an established architect’s own Passive House in Fritchley. View our workRead client reviewsAll services Who we help ## Architects, homeowners andinvestors across Derbyshire ### Architects & design teams Practices who need a contractor that reads a detail properly, flags a buildability issue before it becomes a variation, and delivers the drawn design rather than a simplified version of it. ### Homeowners building individually Families creating a one-off home on their own plot, who want fixed pricing, a written programme and one person accountable for the whole build. ### Period & barn property owners Owners of stone cottages, farm buildings and heritage-sensitive properties who need builders fluent in lime mortar, breathable build-ups and traditional construction methods. ### Landlords & investors Investors converting garages, lofts and commercial space into income. We deliver on time and on budget so the investment starts earning sooner. Mission and standards ## What we stand for, andwhat we won’t tolerate ### Build it once, properly Our purpose is straightforward: hand over buildings that still perform in twenty years. That means foundations, steelwork, roofs, airtightness and drainage designed and installed to the specification, checked by building control at every stage, and never quietly downgraded to protect a margin. ### Price it honestly at the start Every quote is itemised against a written scope so you can see what is included and compare properly. Client-requested changes are priced and confirmed in writing before work proceeds, which is why our final invoices match the figure agreed at the outset. ### Answer the phone You deal with John from first enquiry to handover. Questions get an answer the same working day, decisions are made without a chain of hand-offs, and nobody has to explain the project twice. ### No shortcuts on structure Foundations, steelwork, roofing and load-bearing elements are done once, done right. Every structural element is independently inspected by building control before we proceed. ### Fixed prices, no surprises Quotes are detailed, itemised and fixed. You will never receive an invoice higher than the agreed quote without prior written agreement. ### Direct communication, always You deal with John, not a project manager who has never been on a building site, and not a call centre. When you have a question, you get a direct answer. ### Clean sites, respectful teams Our team cleans up daily. Materials are stored neatly, skips are managed, and your property is treated with respect. ### 10-year structural guarantee Every structural project comes with an underwritten, transferable 10-year guarantee: protection that survives even if you sell the property. ### One team, project after project Directly employed bricklayers, joiners, plasterers, electricians and plumbers who work together on every project, not whoever was free that week.
