New Builds - Single main contractor - Structural engineering in-house - Building Control managed - NHBC / Premier Guarantee compatible - 1-year workmanship guarantee Service overview ## What's involved in new builds. Plain-English breakdown, so you know exactly what you're paying for and why it matters before we set foot on site. ### What it is Ground-up new builds, single dwellings, plot infills, replacement dwellings and small self-build schemes. Groundworks, drainage, foundations, structure, roof, envelope, M&E, internal trades and external works delivered by one main contractor. ### Who it's for Plot owners with planning permission ready to build, self-builders who don't want to manage 25 trades themselves, and small developers building one to four homes. ### When you need it Planning consent granted; structural engineer's calcs produced; warranty provider selected; and you need a fixed price before drawing down development finance. ### Why it matters Self-managing a new build is a full-time job. A single main contractor on a fixed-price contract transfers the programme and budget risk off your desk and onto ours. The cost of doing nothing ## What goes wrong when this is ignored. New builds are won and lost at the contract stage, vague specs and unrealistic programmes are the two biggest reasons self-builds overrun by 30–50%. ### Risks of waiting - Foundations under-engineered for the ground conditions cause settlement that voids the structural warranty. - Poor airtightness and insulation detailing fails the SAP/Part L calculation and stops Building Control sign-off. - Drainage and service runs not co-ordinated cause expensive re-digs once landscaping is finished. - No warranty provider engaged early means the bank withholds the final drawdown. ### Common mistakes - Picking the cheapest quote without comparing what each contractor has actually allowed for in the specification. - Specifying kitchen, bathrooms and finishes mid-build, lead times push the handover by months. - Skipping a contingency line in the budget, every new build finds at least one surprise in the ground. - Trying to project-manage 25 trades and a full-time job simultaneously. Our process ## How the job actually runs. Same system every time. No improvising on your floor. 1. 01 ### Free pre-tender survey Site visit, drawings reviewed, ground conditions assessed and warranty route discussed. 2. 02 ### Fixed written tender Detailed itemised tender within 2–3 weeks covering every trade, material, programme and exclusion. 3. 03 ### Pre-start co-ordination Building Control filed, structural warranty registered, services applications submitted and start date confirmed. 4. 04 ### Build phase Site supervisor on the ground, weekly progress reports, fortnightly cost reports and stage payments tied to milestones. 5. 05 ### Sign-off & handover Building Control completion certificate, structural warranty, SAP/EPC, EICR, and Spectrum 1-year workmanship guarantee. Gas Safe certification provided via our registered partner where required. What you get ## The outcomes that matter. ### One main contractor One number, one invoice, one programme, no co-ordinating 25 trades yourself. ### Fixed-price tender What we tender is what you pay; variations are quoted and signed before extras start. ### Warranty-ready Built to NHBC / Premier Guarantee standards so lenders release final drawdowns. ### Engineered properly Structural calcs, SAP, airtightness and insulation detailed from day one. ### Local supply chain Trusted Kent merchants and trades, no programme stalls waiting on national delivery slots. ### Backed by guarantees Building Control sign-off plus 1-year Spectrum workmanship guarantee on every element we install. In depth ## Everything worth knowing before you book. The details a salesperson skips. Skim it, or read every word, both are useful. Questions on this? Talk to a Spectrum tradesman direct. [07480 485988](tel:+447480485988) ### Single dwellings and replacement homes Most of our new-build work is single dwellings, either a one-off plot or a replacement dwelling where an existing house is being demolished. We handle demolition, groundworks, foundations sized to the ground report, traditional masonry or timber-frame structure, full envelope, M&E, internal trades, external works and landscaping. ### Self-build management Self-builders who want a single point of contact without the burden of running the programme themselves. We take the architect's pack, price it, build it and hand it over to warranty standard, you choose the finishes and the spec, we deliver the programme. ### Small developer schemes Two to four-unit developments for local developers, built to NHBC or Premier Guarantee standards on a fixed-price contract with stage payments tied to lender drawdowns.
