Looking for a builder in Berkshire you can genuinely trust? Trigon Construct manages your home extension or new build collaboratively — with complete transparency over every pound spent. No markups, no hidden costs. Just honest management, trusted local trades, and a fair fee.
Most builders in Berkshire give you a fixed price — then manage their own profit margin behind closed doors. Every decision they make is influenced by what's best for their bottom line, not yours.
Trigon Construct works differently. We act as your construction manager, sourcing and managing specialist local tradespeople on your behalf, while you see exactly what everything costs. Our income is a straightforward management fee, agreed upfront.
This model — Open Book Management Contracting — fundamentally aligns our interests with yours. When we save you money, you keep it. We have no incentive to cut corners or inflate costs.
We work alongside you throughout, drawing on our specialist knowledge of Berkshire's local trades and suppliers to keep your costs as low as possible without compromising quality.
The best results come from genuine collaboration. Rather than disappearing on site for months, we keep you involved at every stage — because your input leads to better decisions and lower costs.
Our deep knowledge of Berkshire's local trades and suppliers means we know who delivers quality, who offers fair pricing, and who to avoid. That specialist local knowledge directly translates into better value for your project.
From choosing tradespeople to selecting materials, you have a genuine say in how your money is spent — guided by our expertise.
We've built relationships with the best local specialists across Berkshire. We know their quality, their pricing, and how to get the best deal for your build.
We proactively look for ways to achieve your vision at a lower cost — and present those options openly so you can make informed choices.
Because our fee doesn't increase with project cost, we're incentivised to find the most cost-effective route to the highest quality outcome.
Understand the real differences between a standard building contract and the way we work.
From first conversation to final handover, you're in control. We handle the complexity — while keeping you fully informed every step of the way.
We meet to understand your vision, budget, and timescales. An honest conversation, no jargon, no obligation.
We work with your architect, refine scope, handle planning where needed, and build a detailed cost plan together.
We tender to our trusted Berkshire trade network. You see all quotes and together we agree who builds your project.
We manage the site daily. Every trade invoice is shared before payment. Monthly cost reports keep you fully informed.
We walk the project with you, compile your snagging list, and remain on hand throughout the aftercare period.
Every quote, every invoice, every site cost is shared with you in real time. Our management fee is agreed upfront as a fixed percentage of construction cost — no trade discounts we keep, no material markups, no hidden rebates.
The fee you agree to is our total income. Nothing more.
We know you're making a significant investment in your home. Here's why homeowners across Berkshire choose Trigon Construct.
Because our fee is fixed, we have every reason to find the best local trades at the best price. When you save money, we celebrate.
You'll never receive a bill you haven't already seen and approved. We operate an open ledger — every penny is yours to scrutinise.
We're based in Berkshire and know the local market, planning environment, and the best specialist trades in the region.
Your home, your decisions. We give you the information to make informed choices — then execute exactly what you want, at minimum cost.
If your plans evolve mid-build, we adapt without the expensive disputes that come with a fixed-price contract.
Your project is run to a proper programme with daily site management, quality control, and a single point of contact throughout.
We focus on Berkshire and the surrounding area — keeping management genuinely hands-on and our relationships with local tradespeople strong.
Whether you're planning a side extension, rear extension, or full self-build anywhere in Berkshire — we'd love an honest conversation about whether our approach is right for you.
