Our Services

Our passion. Our skills.

Architectural Design

We provide full architectural design services from sketch scheme to delivery of the finished project. Whether remodelling, altering extending or replacing a property, we apply our depth of experience on a range of buildings to deliver your project. We work with you to achieve your objectives, and combine design skill with disciplined, cost-effective pragmatism.

The service is flexible according to your needs but can include:

  • Conceptual design
  • Planning applications
  • Listed Building Consent
  • Detailed design
  • Building Regulations approval
  • Specifications and schedules of work
  • Obtaining quotations from builders
  • Administering building contracts
  • Monitoring work throughout construction
  • Cost control through to the final builder’s account

Examples of our design work are shown here and elsewhere on our website.

Building Surveyors

As Chartered Building Surveyors, each with over 30 years’ experience since qualifying, Martin and David offer traditional Building Surveying expertise alongside their Conservation and Design services.

We specialise in the following types of survey:

RICS Building Surveys

We undertake full building condition surveys, generally of period properties, that are beyond the scope of the simpler Homebuyer reports.  Our extensive experience of conservation, repairs and alterations to listed buildings informs our inspections and reports, providing a thorough understanding of the condition and repair liabilities of the property you are purchasing.

Condition Surveys

A condition survey may be required for various reasons.  For example, we have recorded the condition of buildings prior to major works being undertaken, such as the ‘Opening-up’ project at the Royal Opera House, or for historical recording purposes.  Our approach is flexible and can be tailored to your needs.

Maintenance surveys

Planned, preventative maintenance is the best way of ensuring a building remains in good condition over time.  We can report on current condition and provide advice and a plan for prioritised future maintenance.   We have undertaken such surveys at Oxford Colleges, Hospitals, private homes, and schools such as Winchester College.

Subject to compliance with CAA rules, we can include drone and video surveys with our reports.


Martin Hall & David Ensom have worked on all grades of listed and historic properties throughout their long careers and have established themselves as specialists in historic building conservation, their main area of work.

Martin holds a Post Graduate Diploma in the Conservation of Historic Buildings from the University of Bath, and since 2008 has been an RICS Accredited Building Conservation Surveyor  – one of fewer than 120 surveyors in the country with this qualification.

A fully accredited member of the Institute of Historic Building Conservation (IHBC) and a committee member of the local Society For the Protection of Ancient Buildings (SPAB), Martin regularly contributes articles to publications such as Country Life (see Blog), and is a regular speaker at various events and tours of historic buildings.

David has worked on listed buildings of all grades and types for over 35 years, from The Royal Albert Hall to simple rural cottages.  The majority of his workload now involves designing works of repair, alteration and extension to listed properties, and he has a good track record in obtaining Listed Building Consent.

Based on this range and depth of experience we provide bespoke conservation consultancy services to both private clients and professional organisations. We are increasingly asked to provide heritage support services to architectural practices, and to provide independent expert reports on works to listed buildings.
