  • Client requirements and visions
  • Site Analysis and Site Constraints
  • Achievable Goals
  • Regulatory Considerations


  • Structural Engineers
  • Topographical Surveyor

Time estimate for this stage: Between 2 -6 weeks

Stage 2: Concept Design - Taking Shape.

  • Material selections


  • Structural Engineer
  • Arboriculturalist
  • Conservation and Heritage Assessor
  • Energy Assessor
  • Mining and Contamination Specialist

Time for this stage: Minimum 3-4 weeks can take between 3- 6 months depending on the type of project.

Stage 3: Spatial Coordination - Planning Process

After the design phase, securing planning permission may be crucial for your project



  • Local Planning Policies
  • Environmental Impacts
  • Community Consultation


  • Planning Consultant

Time for this stage: Typically takes 8-16 weeks for approval but potentially longer.

Stage 5: Manufacturing and Construction- Getting It Built

Arranging for the works to commence and overseeing the construction, ensuring it meets the drawings.



  • Contractors timeline
  • Issue arising onsite
  • Construction methodologies
  • Materials
  • Weather Conditions
  • Project management


  • General Contractors
  • Sub Contractors (Plumbers, Electricians, etc..)
  • Building Control Inspectors

Time for this stage: Typically takes 6-18 months (Depending on project scale).

Stage 6: Handover -Completion and Fine-Tuning

  • Client feedback
  • Documentation and Certification


  • Project management

Time for this stage: Typically takes 6-12 months (Depending on project scale).

Stage 7: In Use - Enjoy!

This stage focuses on you enjoying your new building.


Activities in this stage include:


  • Evaluating the building’s performance.
  • Providing feedback on its performance.
  • Offering suggestions for improvements.


The architect’s timeline for a project is a multifaceted journey, influenced by various factors and involves collaboration with a range of consultants. Understanding these stages and estimations is essential for the completion of your project. Recognising the influences and engaging the right consultants at each stage, can assist us, as architects, to navigate the complexities and deliver the results within the estimated timeframe.

From conception to completion, a full-service package  based on the following:

Small-scale projects: Renovations, small residential designs, or internal alterations may span from a few months to a year for completion (around 3-6 months for design, approval, and construction).

Medium-scale projects: New dwellings, Listed Buildings, and conversions might range from a year to two years, inclusive of design, approval, and construction phases.

Large-Scale Projects: Complex developments requiring in-depth planning and construction might span several years for completion. These projects encompass intricate designs, approvals, and extended construction periods.
