Building in Magor

New builds in Magor and the surrounding NP26 area

Magor's position on the levels near the M4 has made it one of Monmouthshire's growth villages, and the plots around it suit straightforward, well-built new homes — provided the ground is handled properly. Jac Jones Construction serves Magor and the surrounding NP26 areas with complete new-build construction, our own groundworks team preparing foundations and drainage before the build begins.

The levels around Magor are low-lying and drainage-led: foundations, SuDS and SAB-compliant surface water design are central, not optional extras. That is daily work for our groundworks division, and it is priced into our new builds from the first conversation.

Bespoke homes

From a plot and an idea, or drawings ready to build.

We build bespoke homes in and around Magor the way we build our own developments — because we have been the developer as well as the contractor. That means honest appraisal of the plot and the budget before anyone breaks ground, engineering resolved on paper rather than on site, and one line of responsibility from concept to keys. If you already have an architect, we work alongside them; if you do not, we introduce practices we have delivered with for years.

Groundworks & civils

In-house, on our own plant.

From tight garden excavations to 8-tonne machines on open plots, our groundworks division covers the full package around Magor: excavation and muck shift, foundations and reinforced slabs, drainage and SAB/SuDS works, retaining structures, driveways and finished landscaping levels. One team, one programme, no subcontractor gaps.

Common questions

Questions about building in Magor

Do you build bespoke new homes in Magor?
Yes. We serve Magor and the surrounding NP26 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 Magor 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 Magor, we regularly work across Caldicot, Marshfield, Langstone, Chepstow 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.
