What We Do

Types of Home Renovation Projects We Undertake

Every property is different, and the scope of a renovation depends entirely on what you’re trying to achieve.

Whole House Renovations

Complete property transformations stripping back to shell and rebuilding internally. New electrics, plumbing, heating, layout changes, and full redecoration. The most involved type of renovation, but it delivers the most dramatic results.

Get A Quote

Ground Floor Reconfigurations

Removing internal walls, changing layouts, creating open-plan living. Often combined with rear extensions. Involves structural steelwork, Building Control coordination, and careful sequencing.

Get A Quote

Period Property Renovations

Renovating older properties such as Victorian terraces, 1930s semis, or rural cottages. Renovations are completed while respecting original features and working with traditional construction methods. Balancing modern performance with original character.

Get A Quote

Multi-Room Refurbishments

Coordinated renovation of several rooms as one project including kitchen, bathrooms, and bedrooms together. More cost-effective than piecemeal work over several years, with shared trades and single disruption period.

Get A Quote

Pre-Sale Renovations

Targeted improvements to maximise sale value. Kitchen and bathroom updates, fresh decoration, modernised lighting and flooring – focused where buyers care most and returns are strongest.

Ground-floor refurbishment in Writtle, Essex: open-plan kitchen and living space, new bathrooms, external rendering and a garage part-conversion.

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!

How We Manage Your Home Renovation

Our Process

Renovations are complex as you're working with an existing structure, uncovering unknowns as you go, and often coordinating work in an occupied home. Our structured approach keeps everything on track.

01

Survey & Scope

Thorough survey of the existing property. We assess the building fabric, existing services, structural elements, and areas of concern. From this, we define a clear scope of work with you.

02

Design & Planning

Where structural changes are involved, we work with your architect or recommend one. If planning permission is required, we support the application. For more on planning requirements, see our guide to planning permission in Essex.

03

Detailed Quotation

Fully itemised quotation breaking down every element - structural work, electrics, plumbing, plastering, joinery, tiling, decoration, and materials. Fixed-price wherever possible, with clear allowances for specification choices.

04

Strip-Out & Structural Work

Controlled removal of existing elements, followed by structural alterations (wall removals, new steel beams, new openings). This is where having an experienced team matters most: understanding load paths, sequencing safely, and coordinating with Building Control.

05

First Fix Services

New electrical wiring, plumbing pipework, and heating systems installed while walls are open. Also underfloor heating, ventilation, and smart home pre-wiring. Socket positions, lighting circuits, and bathroom plumbing confirmed beforehand.

06

Finishing, Snagging & Handover

Plastering, tiling, joinery, kitchen and bathroom fitting, flooring, and decoration. Snagging inspection, compliance certificates, warranties, and documentation all handed over. For more on construction sequencing, see our guide: How Long Does a House Extension Take?

Costs & Investment

How Much Does a Home Renovation Cost in Essex?

Renovation costs vary widely depending on scope, property condition, and specification. Here’s a realistic breakdown.

Renovation TypeTypical Cost Range
Single room refresh (cosmetic)£3,000 – £8,000
Kitchen renovation (mid-range)£15,000 – £35,000
Bathroom renovation (full strip & refit)£8,000 – £20,000
Ground floor reconfiguration (structural)£25,000 – £60,000
Full house renovation (3-bed)£80,000 – £180,000+
Full house renovation (4-5 bed, high spec)£120,000 – £300,000+

Costs inclusive of VAT at 20%, which applies to all renovation work on existing residential properties. Figures are indicative and depend on specification, property condition, and structural complexity.

What Drives the Cost?

Property condition is the single biggest variable. Sound electrics and modern plumbing costs far less than full rewiring, replumbing, and structural repairs. Older properties can reveal surprises once opened up, hidden damp, asbestos, or structural movement.

Specification level determines where you sit within the range. Standard fittings and painted walls cost a fraction of bespoke joinery and natural stone. We help you identify where to invest for maximum impact.

Structural work adds cost but delivers the biggest transformation. A single steel beam (£2,000–£5,000) can completely change how a ground floor functions. We present options with clear cost implications.

For kitchen-specific costs, see our kitchen extensions & renovations page. For bathroom budgets, see bathroom renovations & installations.

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!

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.

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.

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.

Frequently Asked Questions

A full house renovation in Essex typically costs between £80,000 and £300,000+, depending on the size of the property, its current condition, and the specification. A three-bedroom semi requiring new electrics, plumbing, kitchen, bathrooms, and decoration might fall in the £80,000–£150,000 range. Larger properties with structural alterations and high-end finishes will sit higher. We provide detailed, itemised quotations based on a thorough survey.

Timelines depend on scope. A single-room refurbishment: two to four weeks. A ground floor reconfiguration with structural work: eight to fourteen weeks. A full house renovation: three to eight months, depending on size and complexity. We provide a clear programme with milestones from the outset.

Most internal renovations don’t require planning permission. However, changes to external appearance, work on listed buildings, or properties in conservation areas may need permission. Building Regulations approval is always required for structural, electrical, and plumbing work. We handle Building Control coordination. See our guide to planning permission in Essex for more detail.

In most cases, renovating is significantly cheaper. Moving costs in Essex (stamp duty, agent fees, solicitor fees, removals, and refurbishment of the new property) can exceed £30,000–£50,000+ for a mid-range purchase. A renovation achieves a better result in the location you already know, often for less than the transaction costs of moving alone.

For single-room or multi-room refurbishments, most homeowners stay, we contain the work area and clean up daily. For full house renovations with new electrics, plumbing, and structural work, temporary accommodation is often more practical. We’ll advise based on your specific scope during the planning stage.

Structural work first (wall removals, steelwork), then first-fix services (electrics, plumbing, heating while walls are open), plastering, second-fix (sockets, radiators, bathroom plumbing), and finally finishes (tiling, joinery, flooring, decoration). Kitchen and bathroom fitting happens during second fix. Getting this sequence right avoids trades clashing and prevents finished work being damaged.

When done well, renovations typically add more value than they cost. A new kitchen can return 60–80% of its cost in added value, bathrooms 50–70%. Structural changes improving the layout, like open-plan living, can add even more because they fundamentally change how the property is perceived. The key is targeting spend on improvements that buyers and valuers recognise.

A renovation involves transforming a space (changing layouts, upgrading specifications, modernising). A refurbishment is more about restoring and refreshing (bringing a tired property back to good condition without changing its layout). Most projects involve elements of both. We use “renovation” as the umbrella term because the majority of our projects involve meaningful transformation.
