Why Attic Conversions Must Be Assessed Before Buying a Property in Ireland

"Attic conversions can add major value to a home — but for buyers, they can also hide serious structural, safety, and legal problems if they weren’t properly designed or certified.

Just because an attic conversion looks finished doesn’t mean it’s compliant. Before buying any property with an attic conversion, a professional assessment is essential to confirm that the space is safe, habitable, and legally sound."

Dermot Mooney - Registered Building Surveyor

Why Attic Conversions Are a Risk for Buyers

Many attic conversions in Ireland were completed:

• Without structural design or calculations

• Without fire safety upgrades

• Without planning checks

• Without Certificates of Compliance

These issues often only surface after purchase, when fixing them becomes costly and stressful.

1. Structural Integrity: Can the Attic Take the Load?

Most attics were designed for storage — not people.

An assessment checks:

✔ Floor joist sizes and supports

✔ Load-bearing walls and steel beams

✔ Alterations to roof structure

✔ Signs of movement or deflection

Poor structure is one of the most common and dangerous defects found in attic conversions. See below image of roof timbers snapped due to load transfer changes caused by attic conversion works.

2. Workmanship: What’s Hidden Beneath the Finish?

A clean finish doesn’t guarantee quality construction.

We assess:

✔ Quality of construction and fixings

✔ Insulation and vapour barriers

✔ Fire-stopping between floors

✔ Evidence of shortcuts or poor detailing

Hidden defects can affect comfort, safety, and long-term value.

3. Is the Attic a Legal, Habitable Space?

Many attics are marketed as bedrooms or offices but don’t meet habitability standards.

We check:

✔ Headroom and usable floor area

✔ Natural light and ventilation

✔ Proper staircase access

✔ Compliance with habitable room criteria

Non-habitable spaces can impact valuation, mortgages, and resale.

4. Fire Safety: A Critical Area of Non-Compliance

Fire safety failures are extremely common in attic conversions.

A compliant attic should include:

✔ Fire-resistant floors and partitions

✔ Fire doors on relevant levels

✔ Protected escape routes

✔ Interlinked smoke alarms on all floors

Fire safety issues can invalidate insurance and pose serious risk to occupants.

5. Planning, Regulations & Certificates

Even where planning permission wasn’t required, building regulations still apply.

We assess:

✔ Planning status and exemptions

✔ Building regulation compliance

✔ Availability of Certificates of Compliance

✔ Risks to mortgage approval or legal completion

Missing or incorrect certification can delay or derail a sale.

Why a Professional Assessment Matters

A visual inspection or estate agent listing is not enough.

A professional assessment:

✅ Identifies hidden defects

✅ Confirms compliance and habitability

✅ Protects buyers from unexpected costs

✅ Provides clarity for solicitors and lenders
