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 key early-stage service:
Heritage Pre-Acquisition Assessment (“Before You Buy”)
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 beyond pre-purchase
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.
Why research & architectural history matters
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.
What this service includes
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.
When this service may be needed
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
