Building in Marshfield
Bespoke homes in Marshfield and the surrounding CF3 area
Marshfield's village character on the levels west of Newport comes with plots that offer space and value — on ground that has to be understood before it is built on. Jac Jones Construction serves Marshfield and the surrounding CF3 areas with bespoke home construction underpinned by in-house groundworks: foundations, drainage and access handled by our own team from day one.
Low-lying ground around Marshfield puts drainage and foundation design at the centre of any build. Our groundworks division treats SAB-compliant surface water strategy and suitable foundation solutions as the starting point, not an afterthought.

Bespoke homes
From a plot and an idea, or drawings ready to build.
Every bespoke home we build is designed around the people who will live in it, and Marshfield projects are no different. Some clients arrive with full planning and a complete drawing package; others have a plot and a rough idea. Both are normal starting points for us. What stays constant is one accountable team: design-and-build support where it is needed, in-house groundworks beneath the build, and a finish standard set by the homes we have built for ourselves.
Groundworks & civils
In-house, on our own plant.
Groundworks are not a subcontract for us — they are half the business. Our own operators and plant handle excavation, foundations, reinforced concrete, retaining structures, drainage and external works across Marshfield and the surrounding CF3 area, both beneath our own builds and as standalone packages. Sites that other builders price as problems are the sites we are set up for.

Common questions
Questions about building in Marshfield
- Do you build bespoke new homes in Marshfield?
- Yes. We serve Marshfield and the surrounding CF3 area from our base in Blackwood, delivering complete bespoke homes from an idea and a plot, or from a finished drawing package. Groundworks, structure, internals and external works are all handled by one accountable team.
- Can Jac Jones Construction manage a project from design through to completion?
- Yes — design and build is a core part of how we work. We can introduce trusted architects, structural engineers, planning consultants, SAP assessors and drainage specialists, then manage the project through planning, engineering and construction to handover. If you already have a design team, we work alongside them.
- Can you undertake the groundworks as well as the house build?
- Groundworks are delivered in-house on our own plant — excavation, foundations, reinforced concrete, retaining structures, drainage and external works. On constrained or sloping sites around Marshfield this is often the difference between a smooth build and an expensive one.
- What information do you need to price a bespoke new build?
- Ideally a drawing package, but a plot and a clear idea are enough to start a sensible conversation. We will tell you honestly what stage the project is really at, what it is likely to involve and what we would need to give you a properly itemised price.
- Do you undertake SAB and drainage works as part of a new build?
- Yes. Surface-water drainage for new builds in Wales requires SAB approval, and SuDS features are designed into our schemes from the start. Our groundworks division builds the drainage and attenuation infrastructure as part of the normal package.
- Which surrounding areas do you cover?
- Alongside Marshfield, we regularly work across Old St Mellons, Langstone, Magor and Caerleon and the wider South Wales region. Exceptional projects further afield — including Bristol and West Wales — are considered on their merits.
- How early should I contact you before I want construction to begin?
- Earlier than most people think. A conversation at plot-or-idea stage lets us flag ground, access, drainage and budget realities while they are still cheap to solve — but we are equally happy to be brought in with completed drawings ready to price.
