Listed Building & Conservation Area Specialists | Orange Property, Brighton & Hove
Brighton is known for its seafront and Regency architecture, yet behind the stucco facades of Kemptown sit materials that are distinctive, complex and easily damaged by inappropriate repair.
At Orange Property we benefit from decades of experience in the use of traditional lime based conservation & repair. Our expertise ensures the correct maintenance methods are used to allow the continued enjoyment of these regal structures.
A few miles inland at Falmer Court Farm, we are undertaking a listed building renovation within a traditional Sussex flint stable block. Different contexts, yet the same principle applies. Historic buildings require informed, sensitive intervention.
This article considers listed building renovation in Brighton and Hove in both context and practice. From Regency terraces in the Kemp Town Estate to rural flint barns on the Downs, Architects, homeowners and managing agents share responsibility for ensuring heritage properties are modernised intelligently while preserving their integrity during listed building renovation Brighton.
Brighton’s Historic Buildings: A City Built in Layers
From Brighthelmstone to Regency Brighton
Brighton began as Brighthelmstone, a modest coastal settlement recorded in the Domesday Book. Its transformation accelerated when the Prince Regent established his seaside retreat and the Royal Pavilion reshaped the town’s identity. Regency architecture in Brighton flourished, and large-scale development followed.
The Kemp Town Estate, Lewes Crescent and Sussex Square
In the early nineteenth century, Thomas Read Kemp laid out the Kemp Town Estate, forming Sussex Square and Lewes Crescent as a bold vision of refined seaside living. Behind their elegant proportions, many houses were constructed quickly, their grandeur masking pragmatic structural methods beneath lime render and stucco.
Through our experience working across Lewes Crescent, Sussex Square and the wider Kemptown conservation area renovation, we regularly see how composed exteriors conceal delicate internal fabric. Brighton’s historic buildings are not simply aesthetic assets. Their structural logic is specific, and it must be understood before intervention.
Understanding Brighton’s Traditional Building Materials
Sussex Flint and Lime Construction
Across the Downs, flint defines the rural landscape. At Falmer Court Farm, the stable block is built in traditional Sussex flint with lime mortar. Unlike brickwork tied together with cement, flint construction depends on lime’s flexibility and breathability to manage movement and moisture.
Our extensive experience at Orange Property in constructing and repairing all types of cobble and flint walling, both shuttered and freehand, gives us the ability to ensure aesthetics and durability go hand in hand.
As part of this listed building renovation in Sussex, rebuilt flint walling and flint repairs have been carried out, using compatible natural hydraulic lime mortar to maintain structural continuity and vapour permeability, and suitably graded aggregate to match the original aesthetic appearance. Where timber required renewal, it was selected to respect the original method of construction. Each decision supports the building’s long-term health rather than imposing modern rigidity.
Bungaroosh and Stucco in Regency Brighton
Many Regency properties in Kemptown, Lewes Crescent, and Sussex Square conceal bungaroosh behind their stucco facades. This locally distinctive mix of pebbles, flint and rubble, bound together with hydraulic lime mortar poured between shuttering, enabled rapid expansion during Brighton’s building boom. It remains durable when maintained correctly, yet it is vulnerable to water ingress and incompatible repairs.
Understanding how these walls were originally constructed and having the skills to maintain and repair them, ensuring they continue to behave exactly as originally intended is essential in preserving their presence for future generations.
We are frequently called to conservation area properties in Brighton where problems have arisen due to previously applied rigid, non porous, cement-based beds, pointing or hard render. While these repairs may have been well intentioned, these materials trap moisture within bungaroosh walls, accelerating decay, or, in the external walls, preventing moisture escape, bringing damage from snap frosts, when trapped moisture freezes and expands, causing render to blow, or pointing to fail.
The original lime-rich construction was designed to breathe, manage moisture, and dry out. When that cycle is interrupted, deterioration often follows quietly behind the facade. Stucco itself plays a protective role. Cracks are rarely cosmetic and should be treated as early warnings.
The expert technicians we employ at Orange Property have been tasked with the careful restoration of these ornate facades, and intricate moulded interiors for decades. Effective conservation and restoration begins with recognising how these materials were intended to function, and continuing to pass these skills on to our next generation of Master Craftsmen.
Timber, Iron and Traditional Roof Structures
Regency Brighton relied heavily on imported Baltic timber for structural framing and cast iron for balconies and railings. With careful maintenance, these elements have endured for two centuries. Repairing rather than replacing preserves both performance and architectural integrity.
Whether restoring a flint barn or undertaking Regency property renovation in Brighton, the principle remains consistent. These buildings were designed to manage moisture naturally. Interventions must work with that logic rather than against it.
The Risk of Inappropriate Repairs in Listed Buildings
Why Cement Damages Historic Fabric
Historic buildings are not forgiving of unsuitable materials. Cement mortars, impermeable renders and poorly considered insulation strategies can disrupt the balance that has allowed these structures to endure. In listed buildings across Brighton and Hove, we often encounter previous works that have unintentionally compounded structural issues.
Balancing Energy Efficiency with Breathability
For Architects, surveyors and homeowners navigating listed building consent in Brighton, the challenge is technical as well as aesthetic. Improving energy efficiency, introducing air source heat pumps or installing underfloor heating within a heritage property must be achieved without suffocating the original fabric. Breathability and compatibility are central to successful heritage renovation.
Listed Building Renovation at Falmer Court Farm
At Falmer Court Farm, the stable block sits within a churchyard boundary among listed structures and open downland. The objective is to create a warm, efficient family home while preserving the character of the original flint building.
Integrating Modern Systems into Historic Buildings
Historic floor levels have been adjusted with care, and a new staircase introduced, The original masonry has been sensitively repaired where necessary with matching lime mortar and flint. Timberwork has been repaired and strengthened to allow continued use. Rooflights have been positioned discreetly to protect the building’s silhouette within its conservation setting. Thermal linings improve performance while maintaining breathability, and underfloor heating paired with an air source heat pump introduces renewable warmth into the eighteenth century shell.
Ecological and Conservation Compliance
The project has also required ecological oversight due to bat roosts, alongside close coordination with conservation officers and consultants. Listed building renovation in Brighton demands collaboration, precision and respect for consented details.
Conservation Area Renovation in Kemptown, Lewes Crescent and Sussex Square
Working Within Brighton Conservation Areas
Working on Listed Buildings within conservation areas in Kemptown and Sussex Square requires a detailed understanding of Regency construction and local authority expectations. Our experience working across these historic terraces informs our approach to material selection, structural alteration and facade repair.
Experience Across Sussex Square and Kemp Town
Conservation area builders Brighton must combine technical knowledge with sensitivity. Every intervention becomes part of the building’s ongoing story. When managed properly, renovation enhances performance without erasing character.
Stewardship of Brighton & Hove’s Heritage Properties
Owning a listed building or heritage property in Brighton is a form of custodianship rather than simple possession. Thomas Read Kemp could not have foreseen how Lewes Crescent and Sussex Square would evolve, nor could the builders of Falmer’s stable block have imagined renewable technologies. Yet their work endures because successive generations chose care over convenience.
Completion at Falmer is scheduled for March 2026. The result will not feel imposed, but like a natural evolution that respects the building’s identity.
From flint barns on the Downs to Regency terraces overlooking the sea, Brighton’s historic fabric demands knowledge, sensitivity and experience. By understanding how these buildings were constructed and how they are meant to function, we can help ensure their longevity.
Caring for Brighton’s heritage is not about freezing it in time. It is about enabling it to endure, responsibly and intelligently.
Care. Built in.
