One of the first questions Dublin homeowners ask us is how long the whole process takes — from first enquiry to finished room. The honest answer depends on the type of conversion, but here's a full breakdown.
Timeline by Conversion Type
| Conversion Type | Typical Duration |
|---|---|
| Velux / Rooflight | 3 – 5 weeks |
| Rear Dormer | 6 – 10 weeks |
| Hip-to-Gable | 8 – 12 weeks |
| Mansard | 12 – 16 weeks |
The Full Process: Step by Step
1
Free Survey (Week 0)
We visit the property, assess suitability, measure up and discuss your requirements. Usually takes 30–45 minutes.
2
Quote & Design (Week 1–2)
Full itemised quote provided. Structural engineer engaged for drawings. Planning exemption confirmed or application submitted if required.
3
Materials Order & Start Date (Week 2–3)
Materials ordered and start date agreed. Party wall notices served if applicable.
4
Structural Work (Week 1–3 on site)
Steel beams, structural carpentry, dormer frame. Roof opened and made weathertight quickly — usually within 2–3 days.
5
First Fix (Week 3–5 on site)
Insulation, electrics, plumbing (if en-suite), staircase installation.
6
Plastering & Finishing (Week 5–8 on site)
Dry-lining, plastering, second fix electrics, windows, flooring preparation.
7
Sign-off & Certification
Building regulation inspection and Certificate of Compliance issued.
💡 The roof is opened and made weathertight within 2–3 days. You won't be left with an exposed roof overnight.
What Can Delay an Attic Conversion?
- Planning permission (adds 8–12 weeks if required)
- Protected structure status — additional assessments needed
- Unexpected structural issues discovered on site
- Bad weather during roof opening phase
- En-suite requiring rerouting of existing plumbing
Can I Stay in the House During the Work?
Yes — in almost all cases. The work is carried out from above and through the attic hatch. The main disruption is the staircase installation, which typically takes 1–2 days. Most Dublin families stay in the house throughout the entire conversion.
