Staircases perform both practical and design functions, providing a conduit between floors and an architectural focal point that helps shape our experience of a building. Their seemingly effortless form is the result of careful coordination and precision. Even an understated staircase requires a multitude of components, each satisfying structural, spatial and regulatory demands. The best heritage staircase renewal schemes go beyond replacement; they improve usability and embed design elements that add to the building’s story.
The success factors for well-executed staircases are determined long before their fabrication or installation. Clear communication between the client, consultant team, contractor and specialist trades creates a shared understanding of the brief from the outset.
Early agreement on what will be preserved and replaced, and the regulations that must be respected, enhances the overall outcome of the programme. This clarity begins with a precise as-built survey and confirmation of finished floor levels, (including existing levels where relevant), aligned with planning policy and listed building consent stipulations. Once parameters are in place, designers gain confidence, and contractors and stair specialists can progress the project into a detailed technical development.
ADAPTING STAIRCASE DESIGN TO CONSERVATION PROJECTS
Historic structures rarely offer perfect symmetry or structural transparency. Uneven geometry, deteriorated sections and legacy alterations often become apparent only once works are underway. The most important task is to accommodate these discoveries without compromise to the architectural vision.
The conservation officer’s priorities will typically centre on the proportions and flow of the staircase, rather than its supporting structure. As a result, the technical and visual aspects must be coordinated in parallel by the project team.
The most effective staircase schemes take a ‘hybrid restoration’ approach, where the historic staircase becomes a framework for new architectural interventions. Original elements such as newel posts, spindles and handrails can be dismantled, restored and adapted to integrate with the updated supporting structure. The unique character of each piece adds visual interest and preserves heritage value, while enhancing sustainability through re-use.
Where additional timber or stone is introduced, choosing compatible varieties and finishes ensures consistency in appearance and texture. As a guiding principle, maintaining continuity in materials, whether timber, metalwork or stone, creates an interplay between old and new, allowing present-day additions to complement, rather than compete with, historic detail.
STAIRCASES AS A HOLISTIC ARCHITECTURAL FEATURE
Highly accomplished staircases are not conceived as ‘steel structure plus finishes’, they are envisioned as a single, holistic piece of architecture. Close collaboration between stair specialists and trades is essential during design development.
Critical junctions, build-ups and intersections – how materials meet and are fixed in practice – must be paid close attention to. The use of 3D visuals to illustrate those connection points can assist the design team with informed decision-making. The surrounding envelope, including wall constructions, door thresholds, shadow gaps, cladding details, landings and fire strategy, should all be considered together. When these elements are aligned from the outset, the finished staircase appears seamless rather than over-detailed and is absorbed comfortably into its heritage surroundings.
Occupying a prominent architectural position, staircases in heritage homes must satisfy modern expectations of safety and functionality, while feeling intrinsic to the original fabric.
Achieving this balance relies on early and accurate information, integrated treatment of structure and finish, and sensitivity to the building’s past. When approached holistically, a modernised staircase strengthens layout and space utilisation, safeguards heritage value and enables traditional craftsmanship to coexist with present-day performance standards. The outcome is a striking centrepiece that facilitates contemporary living while evoking the charm of the past.

WHAT DRIVES SOLID SURFACE SPECIFICATION?
Research from Velstone reveals that the realities behind surface material choice are often more nuanced and contradictory than they first appear.
Velstone surveyed architects and interior designers in the UK for its new white paper, ‘Solid Surface Reassessed’. The findings confirm that solid surface is a trusted and widely specified material, with 41% of respondents saying they always or often specify solid surface, and a further 45% using it occasionally.
Residential projects account for 42% of specifications, particularly in kitchens and bathrooms, while hospitality, commercial and education environments feature strongly. The survey showed architects choose solid surface for its longevity, repairability, design flexibility and colour choice, with these benefits consistently outweighing brand recognition or lead times. Seamless joints, non-porous performance and design ability make it a dependable solution where hygiene, durability and visual coherence matter.
The research also exposed persistent misconceptions, particularly around cost. Some 34% of respondents cite budget as a reason for avoiding solid surface, and 70% say cost is an important factor in surface selection. And yet, when architects move away from solid surface, 37% specify quartz – typically the most expensive option – while only 27% opt for laminate. This contradiction indicates that quartz is frequently associated with luxury, and that cost decisions are driven more by perceived value than by demonstrable performance benefits.
Velstone’s response is a re-engineered approach to solid surface. Its 25mm self-supporting material removes the need for substrate, simplifies fabrication and enables more direct routes to site. This creates a specification model that aligns cost more closely with true material value, while delivering long-term performance backed by ISO 14001 certification.

APEX VENTILATES WELLBEING BUILD
Vent-Axia’s Sentinel Apex commercial heat recovery units have been specified for the Carmarthen Health and Wellbeing Hwb project, delivering energy-efficient ventilation. The refurbishment involved a full reconfiguration of the internal space to create an environment that balances health, wellbeing, and entertainment under one roof.
The 245,000ft2 scheme is repurposing the former Carmarthen Debenhams building into a Health and Wellbeing Hub. The development will have 20 Sentinel Apex units installed across all three floors of the building. The Sentinel Apex units were specified for their energy efficiency, indoor air quality and ultra-quiet operation, as well as meeting stringent Specific Fan Power (SFP) and dBA acoustic requirements.
The Vent-Axia Sentinel Apex is the next generation of commercial heat recovery ventilation, helping specifiers create low-carbon buildings. The Sentinel Apex is specifically designed to have a high level of energy efficiency with industry-leading SFP and low embodied carbon. Individuals will find maximum occupant comfort as this has been a priority for the development of the Sentinel Apex unit, operating quietly while improving indoor air quality.
The Sentinel Apex offers high levels of IAQ and thermal comfort, while maintaining the lowest energy and noise levels. It offers up to 93% heat recovery efficiency (EN308 test method), ultra-low sound levels independently tested and verified by SRL Technical Services, and extremely low SFP. Specifiers can choose from five sizes, as the range delivers airflows up to 4000m3 /hr.
