This early-18th-century Cardiff farmyard is now a rare four-home redevelopment opportunity
This plot contains rare chance to redevelop a historic 300-year-old farmhouse site with permission for four new homes
A 0.61-acre former farmyard in Old St. Mellons has come onto the market, offering a redevelopment opportunity that combines planning certainty with genuine historic interest.
Located on Bridge Road, the site listed on Plotfinder includes an early-18th-century farmhouse – more than 300 years old – alongside an agricultural outbuilding, all set within the village’s long-established rural framework.
Old St. Mellons is one of Cardiff’s oldest settlements, and plots with both heritage buildings and planning permission are highly uncommon here. For developers and self-builders, this listing presents the chance to bring a historic rural property into its next chapter.

The site consists of a traditional farmyard layout anchored by a Grade II listed farmhouse.
The building is recorded as “probably early 18th century,” marking it as one of the older surviving structures in the area. A farm outbuilding forms the rest of the yard, representing the plot’s long agricultural use.
The farmhouse appears on the 1846 tithe map and 19th-century OS mapping, showing that the layout has been part of the local landscape for well over a century.
The current 0.61-acre footprint gives developers room to work with both the heritage setting and the approved redevelopment scheme.

Planning permission for 4 new homes
The site is marketed with planning permission granted for four semi-detached dwellings.
Although the listing doesn’t include a published site plan, it confirms consent for replacing the existing farmyard buildings with four new homes.
Because the farmhouse is Grade II listed, any works affecting it will require listed-building consent. However, the presence of an existing planning approval removes a significant amount of uncertainty for anyone looking to deliver a small residential scheme.
Prospective buyers should request the full planning pack from the agent or local authority to review conditions related to layout, access, design requirements and heritage constraints.
How to buy the plot
If you want to take on this historic self-build plot the guide price is £400,000 with vacant possession on completion.
