    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for providing evidence of systematically comparing at least two viable project solutions against conservation principles, cost, and client brief.
    • Look for documented test methods (e.g., material sampling, mock-ups, structural analysis) and justification of refinements based on test outcomes.
    • Assess whether the candidate can articulate how planning legislation (e.g., Listed Building Consent) and conservation philosophy (e.g., minimal intervention) influenced the final solution.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Structure your evidence around clear stages: initial options appraisal, testing methodology, evaluation of results, and final justification for the refined solution.
    • 💡Reference specific clauses from BS 7913 or ICOMOS charters to anchor your decision-making in recognised conservation standards.
    • 💡Use annotated photographs or diagrams to illustrate how testing revealed weaknesses and led to design modifications.
    • 💡Always refer to the specific legislation and guidance in your answers, and explain how they apply to the scenario.
    • 💡Use correct terminology such as 'significance', 'fabric', 'curtilage', and 'setting' to demonstrate your knowledge.
    • 💡In evaluation questions, consider both the benefits and drawbacks of an approach, and justify your conclusion with evidence.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to adequately document the rationale for rejecting alternative solutions, leaving the decision-making process unsubstantiated.
    • Overlooking non-structural conservation constraints, such as impact on historic fabric or reversible techniques, in favor of purely technical performance.
    • Confusing testing with simple compliance checking; many candidates neglect to demonstrate iterative refinement based on feedback.
    • Misconception: Conservation means freezing a building in time and preventing any change. Correction: Conservation is about managing change sensitively, allowing for adaptation while preserving significance.
    • Misconception: Modern materials like cement are always better for repair because they are stronger. Correction: Cement can be too hard and impermeable, causing damage to historic fabric; lime-based materials are often more compatible.
    • Misconception: Listed building consent is only needed for major alterations. Correction: Consent is required for any works that affect the character of a listed building, including minor changes like repointing or replacing windows.

    How Students Lose Marks (Examiner Pitfalls)

    Common mark loss traps and how to write 100% full-mark answers

    Pitfall: Confusing conservation with restoration, leading to inappropriate intervention strategies.
    ❌ Weak Answer (Loses Marks):Conservation means making the building look like it did originally, so we should replace damaged parts with exact replicas.
    ✅ 100% Model Answer (Full Marks):Conservation is the careful management of change to a historic building, aiming to retain its significance and fabric. It involves minimal intervention, using like-for-like materials and traditional techniques, and prioritising repair over replacement. Restoration, in contrast, is a specific intervention to return a building to a known earlier state, which is only appropriate when justified by evidence and significance.
    Examiner Tip: Always define conservation and restoration separately, and link your answer to the principles of minimal intervention and significance.
    Pitfall: Failing to reference relevant legislation and guidance, such as the Planning (Listed Buildings and Conservation Areas) Act 1990.
    ❌ Weak Answer (Loses Marks):You need permission to change a listed building, but I'm not sure which law covers it.
    ✅ 100% Model Answer (Full Marks):The Planning (Listed Buildings and Conservation Areas) Act 1990 is the primary legislation governing listed buildings. It requires listed building consent for any works that affect the character of a listed building. Additionally, the National Planning Policy Framework (NPPF) provides policy guidance, and Historic England's Conservation Principles, Policies and Guidance (2008) offers a framework for decision-making, based on understanding significance and applying the principle of minimum intervention.
    Examiner Tip: Always name the specific Act and guidance documents, and explain how they apply to the scenario in the question.

    Step-by-Step Worked Solutions

    Detailed solution breakdown for typical exam problems

    Question: A Grade II listed 18th-century brick wall has severe damp problems due to repointing with a hard cement mortar. Propose a conservation approach, including the specification for new mortar and any consents required.

    1. 1.Step 1: Identify the problem: hard cement mortar is impermeable and traps moisture, causing brick decay.
    2. 2.Step 2: Specify the correct mortar: use a lime-based mortar (e.g., NHL 3.5 or lime putty) with a mix ratio appropriate for the bricks (e.g., 1:3 lime:sand), ensuring it is softer than the brick.
    3. 3.Step 3: Outline the repair process: rake out cement mortar to a depth of at least 2.5 times the joint width, dampen the joints, and repoint with lime mortar, finishing to match the original joint profile.
    4. 4.Step 4: State consents: since the wall is listed, listed building consent is required for the repointing works, and it must be carried out by a skilled conservator.
    Final Answer: The wall should be repointed with a lime-based mortar (e.g., 1:3 lime putty:sand) after removing the cement mortar, with listed building consent obtained prior to works.
