Heritage Architecture Consultancy
Your Building's History, Clearly Understood
Ashlar is a specialist heritage architecture consultancy working with owners, developers, and institutions on listed buildings, conservation areas, and historically significant structures. We translate complex regulatory and fabric conditions into clear, actionable guidance — so decisions are made on evidence, not assumption. Most projects stall not from lack of ambition but from incomplete understanding of what a building will allow. Ashlar removes that uncertainty. We assess structural and material condition, engage with statutory consultees, and produce reports that planning authorities and funding bodies trust. The work is methodical. The advice is direct. The outcome is a project that moves forward.
Start My ConsultationThe Approvals Stall. The Brief Gets Complicated.
Heritage planning in the UK operates under a layered consent framework — Listed Building Consent, Conservation Area Appraisals, Historic Environment Records, Section 106 obligations — that rewards those who understand how the system thinks before they submit anything to it. Most delays are not caused by difficult buildings. They are caused by applications that arrive without the groundwork the Local Planning Authority and Historic England need to say yes. Ashlar works at that groundwork level. We are a specialist heritage consultancy with direct experience navigating RIBA-stage projects through statutory and non-statutory heritage bodies across England. Our work begins where most briefs stall: the point where a client knows what they want to do but cannot yet demonstrate — in terms the consent process accepts — why it is appropriate. The pattern is consistent. A client acquires a listed building or a site within a Conservation Area. The design intent is sound. The architect is capable. But the heritage statement is treated as a formality rather than a primary document, the significance assessment is thin, and the application draws an objection from the Conservation Officer that could have been anticipated and addressed before submission. That objection costs time. Time costs money. And the revision that follows is rarely as strong as a submission built correctly from the start. Ashlar exists for clients who have encountered this pattern once and will not repeat it — and for those who want to understand the terrain before they enter it.
Specification Without Compromise
Ashlar operates differently from a stone merchant or a general contractor. The company provides independent stone specification — sourcing, assessing, and recommending natural stone based on the structural and aesthetic requirements of the project, not on what happens to be in a yard. That independence is the foundation of everything Ashlar does. Most stone suppliers have inventory to move. Their recommendations follow from that fact. Ashlar carries no stock bias. The specification comes first. The stone follows from it. This matters because natural stone is not a commodity. Two pieces of the same named material from different quarries can perform entirely differently under load, weather, or tool. Getting the specification wrong is not a minor error. It is one that reveals itself slowly — in staining, in spalling, in joints that open — and by then the remedial cost dwarfs the original saving. Ashlar brings geological literacy to the table alongside design sensibility. The team reads a stone's bedding planes, porosity, and compressive strength the way a structural engineer reads a load calculation. That combination — technical rigour applied to material selection — is not common in the industry. The result is a specification the client can hand to any contractor with confidence. It does not leave interpretation to the site. It closes the gap between design intent and built outcome. Scepticism about stone consultancy is reasonable. The question clients usually carry is whether an independent specifier adds enough value to justify the fee. The answer is found in the projects where the specification was skipped — and in the remedial bills that followed.
The Work Speaks. So Do the Numbers.
Ashlar's project outcomes are drawn from completed commissions — not projections, not averages from the wider industry. Every figure below reflects work delivered under our direct oversight, to specification, within agreed programmes. These are not marketing claims. They are records.
Solved Problems, Documented Across Every Project
Ashlar has delivered completed projects across conservation, restoration, and heritage stonework — each one a documented solution to a specific structural or material problem. This archive represents real commissions, shipped and standing. The cumulative record is the credential. Every project here began with a brief, a survey, and a material decision. Most involved listed buildings, scheduled monuments, or structures requiring RIBA-aligned specification and local authority coordination. None were speculative. All are verifiable. What the wall shows: Ashlar works across a consistent range of problem types — repointing and lime mortar matching, ashlar replacement and indenting, carved stone repair, structural consolidation, and new-build stonework in traditional materials. The methods vary. The standard does not. Clients bring Ashlar in when the scope requires someone who has done this before — not once, but repeatedly, on buildings where error is visible and permanent. That track record is documented here, project by project.
Every Approval Stage, Mapped and Walkable
Ashlar's approval process courses cover the full sequence of consents required for works to historic and listed buildings in England and Wales. Each course addresses a defined stage: pre-application engagement, listed building consent, planning permission, and discharge of conditions. Practitioners leave with a working understanding of what each stage demands, what evidence it requires, and what constitutes a compliant submission. The courses are organised as a sequence, not a menu. You can enter at the stage most relevant to your current project, or work through the full pathway. Either way, each course is self-contained. **What the courses cover:** | Course | Stage Addressed | Typical Duration | |---|---|---| | Pre-Application Engagement | Scoping, heritage statements, LPA dialogue | Half day | | Listed Building Consent | Application structure, supporting documents, conditions | Full day | | Planning Permission for Historic Buildings | Heritage impact assessment, design and access statements | Full day | | Discharge of Conditions | Approving materials, details, and method statements | Half day | Each course is led by practitioners with direct experience of submitting and negotiating consents. The teaching draws on real applications — redacted where necessary — so the examples are grounded in the decisions that planning authorities actually make. Consent refusals most often follow from incomplete heritage impact assessments or poorly scoped pre-application engagement. These courses address both directly.
Others Have Stood Here. They Found a Way Through.
Ashlar clients are typically navigating a listed building, a complex estate, or a planning constraint they did not choose and cannot ignore. These accounts come from people who were in that position. They are not edited for enthusiasm. They are included because they are true. Clients who work with Ashlar report that the clearest value is not the outcome — it is knowing, at each stage, what the outcome was likely to be and why. That clarity does not come from optimism. It comes from experience with the specific systems — Historic England, local planning authorities, conservation officers — that govern what can and cannot be done with a heritage asset.
The Cost of Doing Nothing Is Also Real
Historic fabric that is monitored, maintained, and correctly repaired costs less over time than fabric that is left to deteriorate and then rescued. This is not a philosophical position — it is the consistent finding across planned conservation programmes. Ashlar's work is priced to reflect the full scope of what is required, nothing more. The comparison that matters is not Ashlar's fee against a cheaper contractor's fee. It is Ashlar's outcome against the cost of remedial work five years from now — rotten timber replaced rather than treated, stonework repointed with the wrong mortar and now spalling, a planning enforcement notice that could have been avoided. Ashlar brings RIBA-aligned project management and conservation-specialist oversight to every commission. That means the specification is right before work begins, the contractor is briefed correctly, and the finished result is defensible — to a planning authority, to a heritage body, to an insurer, and to the building itself. One accurate survey costs less than one misdiagnosed repair. One correct specification costs less than one enforcement notice. The arithmetic is not complicated. It just requires the right starting point.
The People Behind Every Project
Ashlar is led by a small, senior team. Every principal holds chartered status and brings direct, hands-on experience to each commission — not oversight from a distance, but authorship from the first meeting to the final sign-off. The practice was founded on a straightforward conviction: that the quality of conservation work is inseparable from the quality of the people doing it. Credentials matter. So does judgement. The two are not the same thing, and Ashlar has always sought both. You will work with the same people throughout. That continuity is not incidental — it is the practice's structure.
Reserve Your Consultation. No Commitment Required.
Ashlar offers an initial consultation to owners, architects, and developers working with historic or traditionally built structures. The session is structured, not exploratory — we arrive with relevant experience and leave you with a clear picture of what the work involves, what it will require, and whether Ashlar is the right fit for it. One conversation. Specific to your building. No obligation to proceed. We work across conservation repair, structural investigation, lime-based construction, and heritage compliance. If your project falls within that scope, this is where it begins.
