TMA in VEFA: Personalising Your New-Build Property
How to Plan Buyer-Requested Modification Works Before Delivery

A practical guide to travaux modificatifs acquereur, the buyer-requested changes that can make an off-plan ski apartment or chalet more practical, rental-ready and comfortable before handover.
What Is TMA in VEFA?
Travaux modificatifs acquereur, usually shortened to TMA, are buyer-requested modification works agreed with the developer before completion of a VEFA property. For Alpine apartments and chalets, these choices can make a major difference to everyday winter use: ski boots, wet outerwear, guest turnover, children, luggage and rental wear all place practical demands on the layout.
What Buyers Can Commonly Modify
Most useful TMA are practical rather than decorative. Buyers often ask for harder-wearing flooring, extra sockets, warmer lighting, walk-in showers, better kitchen storage, owner cupboards, reinforced entrance storage and small layout adjustments where the structure allows it.
- Flooring - durable finishes that cope with snow, moisture and ski boots.
- Electrics and lighting - more sockets by beds, dining areas and work corners, plus better evening lighting.
- Bathrooms - easy-clean surfaces, heated towel rails, extra storage and shower upgrades.
- Storage - wardrobes, boot zones and lockable owner space for rental-ready use.
Timing, Costs and Documentation
The best moment to think about TMA is immediately after reservation. Once materials are ordered or partitions are built, choices narrow quickly. Every approved request should be written, costed, dated and traceable, with before-and-after plans kept with the VEFA file for delivery day.
Start asking practical questions while the reservation contract and notice descriptive are fresh.
Prioritise the changes that affect winter use, rental turnover and long-term ownership.
Ask for an itemised written quote before the developer's TMA deadline.
At handover, compare the delivered property with the approved TMA documents.
Key idea: the best TMA are not necessarily the most expensive. They are the changes that make the property work better from the first winter.
