Heritage Planning Consultants

Respecting the past, reimagining the future

Heritage constraints don’t have to hold your project back. Whether you’re working with a listed building, conservation area, or historic site, successful development depends on balancing heritage protection with commercial delivery.

At Marrons, our archaeology and heritage consultants specialise in heritage impact assessments, archaeology, and strategic planning advice to help manage risk and strengthen your planning case.

Identifying heritage issues early on, managing objections and creating a clear route to consent gives you confidence to move forward. We understand the challenges heritage assets bring to the planning process and the opportunities they create.

From private developments to major regeneration projects, we bring planning insight, technical expertise, and commercial understanding to deliver viable schemes in sensitive environments.

What we do

We’re architects who understand buildability, value and risk, staying involved from first sketch to completion to ensure what’s designed gets built, beautifully and efficiently.

Heritage planning strategy and listed building advice

Every successful heritage project starts with understanding what matters and how change can add value without losing meaning.

Our team gets involved early to uncover opportunities, address constraints, and develop a clear route to consent. Through detailed heritage assessments, setting analysis and design review, we shape strategies that respect heritage significance while supporting commercial goals. 

We work across the full development lifecycle – from early due diligence and land promotion, through to the planning application and post-consent delivery, ensuring heritage considerations are integrated at every stage. 

Managing change is at the heart of what we do. We help clients plan for it, justify it, and deliver it responsibly. 

What this means for you:
Early clarity and confidence that your project strikes the right balance between sensitivity and deliverability, saving time, cost and uncertainty later in the process. 

Example project:
We advised on the transformation of a listed industrial site, creating a heritage-led strategy that celebrated the site’s character and secured approval for new homes and mixed-use development. 

Design, heritage and archaeology integration

Design and heritage go hand in hand.

We work closely with architects, masterplanners and urban designers and planners to develop proposals that respond positively to their historic context, enhancing what’s there while bringing forward something new and purposeful. 

Our specialists prepare Heritage Statements, Townscape and Visual Impact Assessments, and design evidence that explain clearly the story behind a scheme and the benefits it will bring. 

What this means for you:
Planning submissions that tell a persuasive, well-evidenced story – helping decision-makers, consultees and communities see the value in your vision. 

Example project:
For a city-centre regeneration scheme, we worked alongside urban designers and planners to create a proposal that strengthened the historic street pattern while meeting sustainability and design standards, resulting in unanimous planning approval. 

Negotiation, Advocacy and Expert Witness

We believe that constructive dialogue is key to positive outcomes.

Our team engages directly with local authorities, statutory consultees and community stakeholders to build understanding and trust around sensitive proposals. 

We regularly support challenging and sensitive schemes, resolving objections and building the case for approval through clear, evidence-led argument. We also act as expert witnesses at appeal and inquiry, defending proposals where required. 

Our strong local relationships with conservation officers, Historic England and heritage bodies help projects move forward efficiently. While we operate nationally, our local insight and trusted networks ensure we understand the regional context of every scheme. 

What this means for you:
A smoother, more collaborative planning process with fewer surprises and stronger relationships with heritage officers, advisory bodies and the community. 

Example project:
We guided a conservation area regeneration through a challenging planning process, demonstrating how the public benefits and design quality of the scheme outweighed potential harm – helping secure support from all parties. 

Post-consent delivery and compliance

Our involvement doesn’t stop once permission is granted.

We continue to support clients through construction, ensuring that the integrity and story of a heritage asset are carried through every detail. 

This includes managing archaeological fieldwork, advising on materials and shaping long-term management plans to keep heritage integrity on track from consent to completion. 

What this means for you
Confidence that heritage values remain protected through delivery, safeguarding both your investment and the legacy of the place. 

Example project:
We oversaw heritage compliance on a listed building conversion, ensuring that materials, detailing and interpretation met consent requirements while supporting efficient on-site delivery.
