What We Build

Types of New Build Projects We Deliver

No two new build projects are the same. The scope, scale, and complexity of each build depends on the site, the design, and what you’re looking to achieve.

Bespoke Family Homes

For homeowners who have secured a plot of land and want a home designed and built to their exact requirements. We work alongside your architect or can recommend trusted architectural partners, then manage the entire construction process from foundations to snagging. Every detail from the floor plan and room layout to the materials, fixtures, and finishes, is built to your specification.

Replacement Dwellings

Sometimes the most practical route to your ideal home is to demolish an existing property and build something new in its place. Increasingly common across Essex where older properties no longer meet modern standards or the plot offers more potential than the building sitting on it. We handle demolition, site clearance, and full construction.

Plot Development

Building on a purchased plot, whether it’s an infill site, a subdivided garden, or land with existing planning consent, requires careful management of site access, ground conditions, and utility connections. Many plots across Essex come with challenges from clay-heavy soils to protected trees. We assess each plot on its own terms and plan accordingly.

Self-Build Construction Support

If you’ve designed your own home or engaged an architect independently, we provide the construction expertise to bring those plans to life. As your main contractor, we manage all trades, coordinate Building Control inspections, and ensure the build progresses on schedule. You stay in control of the design decisions; we handle the construction delivery.

How We Build Your New Home

Our Process

Building a house is a complex, multi-stage process that typically spans nine to eighteen months. We follow a structured approach that keeps things moving efficiently while maintaining the quality standards we're known for.

01

Initial Consultation & Feasibility

We visit the site, review your plans or brief, discuss budget and timeline, and assess practical considerations - access, ground conditions, services, and planning constraints. If the project is viable, we provide an initial cost indication and outline the next steps.

02

Design & Planning

We work alongside your architect to review designs for buildability and cost efficiency. If you need architectural support, we recommend experienced professionals who understand Essex's planning landscape. We support the planning application process, liaising with your local council, whether that's Chelmsford, Colchester, Braintree, or any other Essex authority.

03

Building Regulations & Engineering

Detailed building regulations drawings are prepared alongside structural engineering calculations - covering foundation design, steel specifications, insulation values, and energy performance. Every new build must meet current Part L energy efficiency and Part S EV charging requirements.

04

Groundworks & Foundations

Construction begins on site with clearance, excavation, drainage installation, and laying foundations. Essex is predominantly clay soil, which often requires deeper strip foundations or piled foundations to account for seasonal ground movement. Below-ground drainage and service connections are installed during this phase.

05

Superstructure

Walls, floors, and structural framework go up. Whether the design calls for traditional masonry, timber frame, or a combination, our team builds to precise tolerances and ensures every structural element is correctly installed and inspected.

06

Roofing & Weatherproofing

The roof structure is erected and the building is made watertight - including tiling/slating, fascias, soffits, guttering, and any roof windows. Once weathertight, internal work progresses without delays.

07

First Fix

Internal infrastructure is installed - electrical wiring, plumbing pipework, heating systems, and any underfloor heating. This happens before plastering, while walls and floors are still accessible. Socket positions, lighting layouts, and bathroom configurations are finalised beforehand.

08

Plastering, Insulation & Dry Lining

Internal walls are insulated, plasterboarded, and skimmed to create smooth, finished surfaces. The insulation specification meets energy performance requirements, and every element, from wall insulation to acoustic separation between floors, meets or exceeds the required standards.

09

Second Fix & Finishes

Where your new home comes to life. Kitchen fitting, bathroom installation, doors, skirting boards, electrical and plumbing connections, flooring, tiling, decoration, and bespoke joinery. The level of finish is entirely your choice. For inspiration, see our kitchen extensions & renovations and bathroom renovations pages.

10

Snagging, Inspection & Handover

Thorough snagging inspection, Building Control final sign-off, completion certificate issued. We walk you through the finished property, hand over all documentation including warranties and compliance certificates, and ensure you're completely satisfied.

Project TypeTypical Construction Duration
2–3 bedroom home9 – 12 months
4–5 bedroom home12 – 16 months
Replacement dwelling10 – 14 months
Complex or bespoke design14 – 20 months

Construction phase only. Allow 3–6 months for design, planning permission, and building regulations before construction starts. For a detailed look at construction timelines, read our guide: How Long Does a House Extension Take?

Costs & Investment

How Much Does It Cost to Build a New Home in Essex?

Building a new home is a major financial commitment. Having a realistic understanding of the numbers from the outset helps you plan effectively and avoid unwelcome surprises.

£2,200 - £3,500+
per square metre — depending on specification, site conditions, and design complexity. Construction costs only, excluding land, professional fees, and external works.

What Influences the Cost

Site conditions play a significant role. A straightforward, flat site with good access and existing service connections will be less expensive to develop than a sloped plot with poor ground conditions. Much of Essex sits on London Clay, which can require deeper or more specialist foundations, an additional cost to factor in early.

Specification level is the biggest variable within your control. A standard specification using quality but cost-effective materials will sit at the lower end. A high-specification build with bespoke joinery, underfloor heating throughout, premium fittings, and extensive glazing will push towards the upper end.

Design complexity also affects cost. A simple rectangular footprint with a standard pitched roof is significantly less expensive per square metre than a property with multiple roof lines, curved walls, or extensive basement works.

Indicative Construction Costs

Home SizeBasic SpecificationMid SpecificationHigh Specification
90m² (2–3 bed)From ~£198,000From ~£252,000From ~£315,000+
130m² (3–4 bed)From ~£286,000From ~£364,000From ~£455,000+
180m² (4–5 bed)From ~£396,000From ~£504,000From ~£630,000+

Construction costs only. Excludes land purchase, architect fees (typically 8–12% of build cost), structural engineer fees, planning and building regulations fees, utility connections (£5,000–£15,000+), and external works.

Where the Budget Goes

Groundworks and foundations typically account for 10–15% of the overall build cost, though this can increase on challenging sites. The superstructure (walls, floors, and roof) represents the largest element at around 25–30%. Roofing and weatherproofing falls between 8–10%. First fix mechanical and electrical work accounts for approximately 15–18%, while second fix and finishes represent 20–25%. External works make up the remaining 5–10%.

💡 Important: VAT on New Builds Is Zero-Rated

Unlike renovation or extension work, new build construction in the UK is zero-rated for VAT. You won't pay the standard 20% VAT on construction costs - a significant saving that can make a new build more financially viable than many homeowners expect. This applies to genuinely new, self-contained dwellings.

It totally exceeded all our expectations!

The Belvia Construction Company have recently finished our single storey extension. I cannot recommend James and his whole
team enough. Every single one of them worked so hard, were very helpful, polite and considerate and gave us immense confidence in their workmanship. James kept to his schedule and was extremely organised and hands on. He offered advice when we were hesitant, but equally was always willing to make a few minor changes along the way.
The team made what we had been fearing would be a huge upheaval, so much easier and more pleasant than we ever expected!
James said he wanted us to come down each morning and really love our extra space – it totally exceeded all our expectations!
We would recommend The Belvia
Construction Company 100%!
Thank you, James and Co!

Jimi and the team were professional throughout the renovation of our main bathroom.

A superb job of our new kitchen

James and his excellent team at Belvia made a superb job of our new kitchen. Right from the planning stage, it was clear we were dealing with people who have a great eye for detail and really care about doing the job well. When the work started, they were totally reliable, arriving when they said they would and leaving the kitchen neat and tidy at the end of each day. We are really pleased with the result and would recommend Belvia to anyone who is looking for an expert builder. It was also definitely good value for money, and we are delighted with the work. Thank you, again, James!

We would recommend Belvia Construction to everyone!

We would recommend Belvia construction to everyone! James and his team are excellent and their attention to detail, quality of work and efficiency was very welcomed with a project scheduled to wrap ready for Christmas, and delivered just in time for the tree to make an appearance and all our family to arrive to stay!
We set out to remodel and renovate the downstairs of our home & the exterior facade and were so impressed throughout the 4month build process. Welcoming a team into your home with 2 young children and whilst living upstairs can feel a little daunting but the team were just brilliant, super approachable, lovely with the kids and so easy to have with us, not to mention spotlessly tidy!

James’ communication was fantastic throughout the planning phase and whilst the build was underway, both on-site and over email & whatsapp. Nothing ever felt too much trouble (even when we hit the natural challenges of a remodel of an old property), he was always great at helping us steer toward decisions when needed, giving us advance warning of key deadlines and timelines for materials or fittings to arrive, and is a true professional!
We are already planning our next project with the Belvia team and really can’t thank them enough for all their hard work landing our project and creating a space we love – and all importantly, on time and to budget! Thank you!

The attention to detail and communication level was second to none

James and his team at Belvia were responsible for overseeing a refurbishment of our main family bathroom.
This is the second time we’ve had Belvia in our home, previously it was for a rear extension of our property some 5 years ago.

Whilst this project is nowhere near the size of our first with James, the attention to detail and communication level was second to none. Belvia combined multiple trades to ensure a smooth transition as the project progressed and we couldn’t be happier with the finished product.

Couldn’t recommend enough.

Outstanding 5 star building services from Belvia Construction

From the start Jim gave us total confidence that Belvia were an incredibly professional and capable building company. They always arrived when they promised, they left everything tidy, the lads (Ryan, Ellis & Luke) were very polite and knew exactly what they were doing. Every aspect of the build was undertaken with the highest level of quality. Things we mentioned early on in the process were remembered and implemented exactly as we required. Our friend (also a builder) visited and was really impressed with the finish, which is no mean feat.

We are overwhelmed with the final result – it is even better than we expected and there is nothing we would change. We would 100% recommend Belvia Construction. Many thanks to Jim and the team.

Why Choose to Build a New Home in Essex?

Advantages

There are compelling reasons why more homeowners across Essex are choosing to build rather than buy.

Complete Design Freedom

A new build is designed around your life. You decide the room sizes, layout, flow between spaces, ceiling heights, and window positions. No compromising on a property designed for someone else's needs.

Energy Efficiency & Lower Running Costs

New builds achieve significantly higher energy performance ratings than older properties. With proper insulation, air-tight construction, and efficient heating systems, your running costs will be considerably lower.

Modern Building Standards

Current regulations require higher levels of structural integrity, fire safety, and accessibility. Your home will also be pre-wired for EV charging under Part S compliance — increasingly important as the UK transitions away from petrol and diesel.

Long-Term Value

A well-designed, well-built new home on a good plot in Essex represents a strong long-term investment. With average Essex property prices around £414,000, a bespoke new build in a desirable location holds its value exceptionally well.

Frequently Asked Questions

A self-build is any project where you commission the construction of your own home, rather than buying a finished property from a developer. Within that, you can choose how much you do yourself. Some self-builders manage trades directly and carry out some of the work themselves. Others appoint a main contractor, like Belvia, to manage the entire construction process while they focus on the design decisions and overall vision. We work with many self-builders in Essex who want professional construction management with the flexibility to choose their own finishes.

No. New build residential construction is zero-rated for VAT in the UK. This means you don’t pay 20% VAT on the construction costs, which is a significant financial advantage compared to renovation or extension work, where VAT applies at the standard rate. The zero-rating applies to genuinely new, self-contained dwellings. Your architect or tax advisor can confirm eligibility for your specific project.

Essex predominantly sits on London Clay, which expands and contracts with moisture changes. This means foundations typically need to be deeper than in areas with more stable ground – often 1.5 metres or more, depending on the proximity of trees and vegetation. Strip foundations are the most common, but trenchfill, raft, and piled foundations may be required depending on the specific site conditions. We assess ground conditions as part of our initial feasibility review.

It’s possible, but it depends on local planning policy. Garden land is classified as previously developed land in many cases, and some Essex councils are more receptive to garden plot development than others. Key considerations include whether the plot has independent access, whether the new dwelling would impact neighbouring properties, and whether the design is in keeping with the surrounding area. We’d recommend getting a pre-application opinion from your local planning authority before committing to a purchase.

All new build homes should carry a structural warranty – typically valid for ten years. This can be provided through schemes such as NHBC Buildmark, Premier Guarantee, or Advantage. We also provide our own defects liability period during which we’ll address any issues arising from materials or workmanship. Full documentation, compliance certificates, and warranty details are handed over at project completion.

Construction costs for a new build in Essex typically range from £2,200 to £3,500+ per square metre, depending on the specification level, site conditions, and design complexity. A standard three-to-four bedroom home of around 130 square metres could cost between £286,000 and £455,000+ for the construction phase alone. This excludes land purchase, professional fees, utility connections, and external works. We provide detailed quotations based on your specific plans and site conditions.

The construction phase for a typical new build home takes between nine and eighteen months, depending on the size, complexity, and specification of the project. Before construction starts, you should also allow three to six months for design development, planning permission, and building regulations approval. We provide a detailed programme at the start of every project so you know exactly what to expect and when.

Yes. Almost all new build projects require full planning permission from your local council. This includes bespoke homes on new plots, replacement dwellings, and conversions of existing buildings into new residential units. We work alongside your architect to support the planning application process and can recommend experienced planning consultants if needed. For more on how planning works in Essex, read our guide to planning permission.
