Research & Architectural History


Research & Architectural History services provide a detailed understanding of historic buildings, their development, significance and context. Through archival research, historic mapping and architectural analysis, Logan’s ARCH supports informed decision-making for owners, professionals and organisations working with historic and sensitive buildings.

This service supports projects at all stages — from early research and feasibility, through planning and conservation, to long-term management and interpretation.


A Heritage Pre-Acquisition Assessment is one application of Research & Architectural History, designed specifically for clients considering the purchase of a historic or older building.

This early-stage assessment helps clients understand what they are buying before committing, by addressing questions such as:

  • What is the age and historic development of the building?
  • Does it have heritage significance or designation?
  • Are there likely planning or conservation constraints?
  • What sensitivities, risks or opportunities should be considered?

This service provides clarity at the outset and can help avoid unexpected restrictions, costs or delays later.

Research & Architectural History services are also commissioned to:

  • Support heritage and planning assessments
  • Inform repair, alteration or change-of-use proposals
  • Understand complex or multi-phase buildings
  • Provide evidence for conservation strategies
  • Assist with long-term stewardship and management

This work often forms the foundation for further services, including historic building recording, materials analysis and digital documentation.

Understanding how a building developed — and why — helps to:

  • Identify heritage significance and historic character
  • Explain alterations and surviving fabric
  • Inform sensitive, proportionate interventions
  • Support planning and conservation decision-making
  • Reduce risk and uncertainty at an early stage

Clear, well-evidenced research ensures proposals are informed, defensible and appropriate.

Research & Architectural History may include:

  • Archival research using historic maps, plans, photographs and documents
  • Architectural analysis of form, materials and construction
  • Investigation of building phases and development
  • Assessment of heritage and historic significance
  • Contextual research relating to landscape or settlement history
  • Written reports presented clearly for clients, planners and stakeholders

All research is proportionate to the building and the project stage.

Research & Architectural History services are commonly commissioned:

  • Before purchasing a historic or older building
  • At early feasibility or project planning stages
  • Prior to planning or conservation applications
  • Where a building’s development is unclear or complex
  • To support long-term conservation and management

If you would like to discuss how research and architectural history could support your project — whether at an early stage or as part of a wider conservation strategy — Logan’s ARCH can advise on the most appropriate approach.
