A well-designed loft conversion is one of the smartest ways to add living space — and increase your home’s value. But how much value can it really add in Hampshire?
Let’s break it down for homeowners in places like Winchester, Alton, and Fleet.
📈 The Short Answer: 15%–20% Added Value
According to Rightmove and Nationwide, a quality loft conversion can add between 15–20% to your home’s value — depending on location, layout, and finish.
In Hampshire’s competitive markets (e.g. Lymington, Petersfield), this can mean £60,000–£100,000+ added to your home’s sale price.
🧱 Types of Loft Conversions & Their ROI
| Conversion Type | Approx. Cost (Hampshire) | Value Added |
|---|---|---|
| Velux (rooflight) | £20,000 – £35,000 | Up to 15% |
| Dormer | £35,000 – £55,000 | 15–20% |
| Hip-to-Gable | £45,000 – £60,000 | 15–20% |
| Mansard | £60,000+ | 20%+ |
Dormers are popular in homes in places like Totton, Chandlers Ford, and Waterlooville for their balance of cost and space gain.
🛏 What Adds the Most Value?
- Extra bedroom + en-suite bathroom
- High-quality insulation and finishes
- Natural light (via rooflights or dormers)
- Smart space planning by an architect
Buyers in Alresford, Hook, and Yateley often prioritise usable square footage over just the number of rooms.
🛠 Planning & Building Regulations
- Most loft conversions don’t need full planning permission (under Permitted Development), but always check with your local authority.
- You will need Building Regulations approval, especially for stairs, structure and fire safety.
A Hampshire architect can help you navigate this process with ease.
Finally
A loft conversion isn’t just about adding space — it’s a smart investment in your Hampshire property’s value. Get it designed right, and it could pay for itself when you come to sell.
