Whether you’re planning a family home, an apartment conversion, or a new commercial unit, we provide the structure, planning, and project management to bring it to life.
Our team covers residential (house extensions, loft conversions and house renovations) and commercial work across London and the South East, from straightforward builds to complex design-and-build schemes. We manage every part of the process in-house, with an experienced team that includes architects, engineers, builders, and project managers.
Residential Projects: Homes Built Around You
Your home should reflect your lifestyle. Whether it’s a new build from the ground up, a house extension, a complete house renovation, or a loft conversion to create extra living space, we work closely with you to shape a design that works for your day-to-day needs and plans. Every family is different, so every home we build is too.
Commercial Projects: Building for Business
We also deliver custom-built spaces for commercial use, from new offices and shop units to hospitality venues. For clients refurbishing bars, restaurants, or retail spaces, we help reconfigure interiors to enhance foot traffic, customer flow, and revenue. If you’re expanding or starting from scratch, our commercial build team will ensure your space is built with purpose and longevity in mind.
Design & Build: Everything in One Place
Some clients come to us with architects already on board. Others prefer to keep the whole project under one roof. Our design-and-build service means we handle everything, from architectural design and planning permission to construction and final handover. You’ll have a single point of contact throughout, with progress updates through our secure online portal.
A Complete, Hands-On Service
We take care of the full project lifecycle. That means one team manages design, planning, approvals, construction, and finishing touches, making the entire process simpler and more efficient for you. Our in-house architects and engineers work alongside skilled tradespeople to keep your project running smoothly, safely, and on budget. If you need support with local authority planning permission or help navigating building regulations, we’ll handle that too, drawing on our strong track record across London boroughs and surrounding counties.
Built Around You
Every project starts with a detailed consultation, during which we listen carefully to what you want. From there, we can produce architectural drawings, 3d visuals, or CGI renderings to help you visualise how the space will look and feel before a single brick is laid. Whether you’re after a clean, modern office layout or a warm, characterful family home, our approach is collaborative and focused on the real people who’ll use the space every day.
Workmanship You Can Rely On
We don’t cut corners, literally or figuratively. Every material, fixture, and finish is carefully considered. From the foundation to the final coat of paint, our work reflects our pride in doing things correctly.

About Our Journey.
New Build Contractors was founded by people with years of experience working on active construction sites. We have completed residential, commercial, and healthcare projects, and we know how quickly things can go wrong when responsibility is unclear or communication fails.
That’s why we created a company that pays attention to every detail, takes responsibility from start to finish, and communicates clearly with both clients and consultants. Today, most of our work comes from repeat clients and referrals from other professionals. To us, this shows that our approach works in real life, not just in theory.
At New Build Contractors, our mission is to deliver new build projects clearly, honestly, and with strong management from the very start. We make sure the basics are right, with solid planning, good sequencing, and experienced people on site who can make smart decisions when things change.
Instead of moving forward without a plan, we take time to learn what our clients need, how the building will be used, and where potential risks may arise. This way, we can solve problems early, keep schedules realistic, and deliver buildings that work as they should long after handover.
Our vision is to be a new-build contractor clients trust to get things right in every way: technically, commercially, and practically. We aim to be known for reliable delivery, well-managed sites, and buildings that meet regulations, budgets, and expectations without causing unnecessary disruption.
As standards for sustainability, safety, and performance evolve, we continue to invest in better planning, stronger site management, and more efficient construction. Most importantly, we believe long-term relationships come from keeping our promises, taking responsibility when challenges arise, and delivering work we are proud of.
New Build Services That Fit Around You
We regularly help clients navigate the planning process, often while they remain in their current property until work is ready to begin.
We’ll help assess what’s achievable on your site, considering budget, planning, and space use.
Our New Build Contractors team has been working for over a decade now. We offer a warranty and guarantee with our work.
We’ll guide you through the practical and financial aspects of your new build, managing the whole process safely and efficiently.
At New Build Contractors, we feel every home should be built upon the foundation of your imagination, which is why our process focuses on your vision, lifestyle and aspirations. We listen because we want to know not only what you need today, but also how your home can work best for you in the future.
01
Concept Creation
We begin by listening to you. We take your ideas, learn how the building should work day to day, and turn them into a concept that fits your design, budget, and construction needs.
02
Design and Planning
After we agree on the direction, we work out the design details. We plan layouts to meet regulations, work well on site, and help prevent delays or extra work later.
03
Visual Presentation
We create clear 3D visuals so you can see how your project will look. This helps you review details, make decisions, and adjust the design before construction begins.
04
Project Management
From design to delivery, we manage the schedule, work with consultants, and guide site teams to keep everything on track and moving forward.
Built for London. Specifically.
London isn’t like anywhere else to build in. Conservation areas, party wall disputes, Victorian foundations, basement flood risk, heritage facades, high-density plots, every borough throws up its own challenges. We’ve worked across all of them.
Understanding the planning landscape in Islington isn’t the same as understanding it in Bromley. Knowing how to approach a party wall in Hackney isn’t the same as in Richmond. We’ve navigated all 33 London boroughs, and we know the local details that can make or break a project timeline.
Some of the London-specific knowledge we bring to every project:
- Conservation area restrictions and what’s achievable within them
- Permitted development rights and the borough-by-borough exceptions that catch people out
- Party wall agreements and how to manage them without derailing timelines
- Victorian and Edwardian structural considerations specific to London’s housing stock
- Planning application history across local authorities , we know what gets approved and what doesn’t
- Local authority building control relationships, developed over a decade of London projects
We don’t just build in London. We understand it.
Why More London Homeowners Are Building Rather Than Moving
London’s property market has made one thing increasingly clear: moving up the ladder costs more than it used to. Stamp duty, agent fees, and the gap between what you can sell for and what you need to buy means that for many homeowners, extending or converting is now the more financially sound decision.
At the same time, the government’s renewed focus on housing delivery, including relaxed permitted development rights and increased pressure on local authorities to approve more residential schemes, has opened up more opportunities for homeowners and developers alike.
If you’ve been sitting on an unused loft, a side return that’s never been touched, or a plot of land you haven’t known what to do with, right now is a good time to find out what’s possible. London property values mean that a well-executed extension or new build doesn’t just improve your life,it adds real, measurable value to your most important asset.
We’re seeing more enquiries than ever from homeowners who’ve done the maths and realised that building is better than buying. If you’re one of them, we’d be glad to help you work out what’s achievable.
