Building in Cyncoed
Bespoke homes in Cyncoed and the surrounding CF23 area
Cyncoed's generous plots and established avenues make it one of Cardiff's strongest locations for substantial individual homes — and for the indoor pools and leisure spaces that increasingly come with them. Jac Jones Construction serves Cyncoed and the surrounding CF23 areas as a complete bespoke builder: we can take a project from a plot and an idea through design, planning and engineering, or step in with a finished drawing package and build it.
High-end residential work in Cyncoed tends to happen in established gardens, where access, drainage and neighbourly discretion matter as much as the architecture. Our in-house groundworks team handles tight-access excavation and services without bringing in a chain of subcontractors, and our pool work is delivered as part of the build rather than bolted on afterwards.

Bespoke homes
From a plot and an idea, or drawings ready to build.
The difference between a bespoke home and an expensive one is usually the ground and the detail. Around Cyncoed, we handle both in-house: our groundworks division prepares the site, our build team delivers the structure and envelope, and the internal finishes are completed by trades we have worked with for years. You deal with one company, one programme and one person who answers the phone.
Swimming pools
Pools built as part of the project, not after it.
Indoor or outdoor, a pool near Cyncoed needs the same things: properly engineered groundworks, a reinforced shell built to last and finishes that survive the chemistry. We deliver the complete package in-house, from the dig and the shell through tiling, plant and the terrace or pool hall around it.
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 Cyncoed and the surrounding CF23 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 Cyncoed
- Do you build bespoke new homes in Cyncoed?
- Yes. We serve Cyncoed and the surrounding CF23 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 Cyncoed this is often the difference between a smooth build and an expensive one.
- Do you build indoor and outdoor swimming pools in Cyncoed?
- Yes. We construct reinforced pool shells, plant areas, enclosures and surrounds as part of the main build or as a dedicated project, so the pool is engineered with the house and the ground rather than treated as an afterthought.
- 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 Cyncoed, we regularly work across Lisvane, Llanishen, Rhiwbina, Pontcanna and Llandaff 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.
