Conserving significance, enabling change
OA have extensive experience working within listed buildings, conservation areas and historically sensitive environments.
We approach each project with respect for the architectural, cultural and material value of the site, carefully balancing preservation with the need to support contemporary use. Our role is to understand significance first, allowing us to then make informed decisions about repair, alteration, extension or adaptation.
From careful repair to transformative renewal
Our work ranges from essential fabric repairs and conservation-led restoration to comprehensive refurbishment, reconfiguration and the introduction of new buildings within historic settings.
We are experienced in developing proposals that enhance viability and usability while remaining sympathetic to scale, character and setting.
Integrating modern performance
Adapting heritage buildings for present-day expectations requires thoughtful technical resolution.
We work to improve environmental performance, accessibility and life safety while respecting existing spatial fabric and minimising intervention. Through careful detailing and coordination with specialist consultants, we ensure that contemporary requirements are met in ways that are discreet, reversible where appropriate, and sensitive to the original architecture.
Guiding projects through consent and approval
Successful work in heritage contexts depends on early dialogue and clear strategy.
We prepare Listed Building Consent applications, heritage statements and supporting documentation, and work collaboratively with conservation officers, planning authorities, amenity societies and wider stakeholder groups. By managing process as carefully as design, we help clients navigate regulatory pathways with confidence and clarity.
Sustaining heritage for future generations
Our ambition is to secure long-term futures for important buildings and places.
By aligning conservation principles with practical delivery, we create solutions that protect historic significance while allowing sites to evolve and remain relevant. The result is heritage that continues to serve communities, institutions and owners for many years to come.
“OA delivered a pragmatic solution to replace over 8,000m² of RAAC roof structure across our Grade I listed campus. Their leadership through planning, listed building consent and construction has been exemplary, guiding a complex heritage project with skill, care and outstanding technical competence.”
