Loft Conversion Planning Checklist
Everything to consider when planning a loft conversion
When to Use This Checklist:
Use this checklist during the early planning stages of your loft conversion project.
A loft conversion is one of the most cost-effective ways to add space to your home. However, proper planning is essential for success. This comprehensive checklist covers everything from initial feasibility to final preparation.
1. Feasibility Assessment
Measure head heightImportant
You need minimum 2.2m at the highest point for a usable conversion.
Check roof structure
Traditional rafters are easier to convert than modern trusses.
Assess space available
Consider floor area at usable head height, not just total area.
Check chimney breast
Active chimneys affect layout options; dormant ones can be removed.
Review access options
Where can stairs go without losing too much space below?
2. Planning & Permissions
Check permitted development rightsImportant
Most rear dormers don't need planning permission, but verify first.
Review conservation area restrictions
Conservation areas have stricter rules about external changes.
Consider party wall agreementsImportant
Required if work affects shared walls with neighbours.
Apply for building regulations
All loft conversions require building regulations approval.
Check lease (if leasehold)
Leasehold properties may require freeholder consent.
3. Design Decisions
Choose conversion type
Velux, rear dormer, L-shaped, hip-to-gable, or mansard.
Plan room layout
Bedroom, en-suite, storage areas - work with head height constraints.
Design staircase
Location, style, and building regulations compliance.
Specify windows
Size, type, and positions for light and ventilation requirements.
Plan storage
Eaves areas make excellent built-in storage.
4. Contractor Selection
Get 3+ detailed quotes
Compare like-for-like specifications, not just prices.
Check referencesImportant
Visit completed projects and speak to previous clients.
Verify insurance
Public liability and employer's liability are essential.
Review contract terms
Payment schedule, timelines, and what's included.
Check warranty/guarantee
What protection do you have after completion?
