Space above your head

The extra room you already own

Most homes have a whole floor of potential sitting empty under the roof. A loft conversion unlocks it — giving you a genuine extra room without losing an inch of garden or moving house.

Viskonti Ltd designs and builds loft conversions across Cheltenham and Gloucestershire, from Victorian terraces and 1930s semis to modern estate homes. We assess your roof honestly, tell you exactly what’s achievable, and create a light, comfortable room that feels like a natural part of your home.

From the first drawing to the last skirting board we handle everything: structural work, staircase, insulation, glazing and finish. Fully insured, tidy and reliable, with full building-regs support so the job is done right.

Types of conversion

The right conversion for your roof

Every roof is different — we recommend the style that gives you the most usable space for your budget.

🏘️

Dormer conversions

The most popular choice — a box-shaped extension to the roof that adds generous headroom and floor space.

📐

Hip-to-gable

Ideal for semi-detached and end-terrace homes, extending a sloping side up into a vertical gable wall for more room.

☀️

Velux / rooflight

The most cost-effective option where headroom already exists — smart rooflights flood the space with daylight.

🏛️

Mansard conversions

A near-vertical rear roof that maximises space and suits period and terraced properties, often in conservation areas.

🚗

Garage conversions

Not up in the roof, but the same idea — turn a cold, under-used garage into a warm, usable room.

⬇️

Basement conversions

Create valuable extra space below ground with proper tanking, drainage and lighting for a dry, comfortable room.

Loft conversion FAQs

What type of loft conversion is best for my home?

It depends on your roof shape and how much space you want. Velux conversions suit lofts that already have good headroom, dormers add space to most homes, hip-to-gable works well on semis and end-terraces, and mansards suit period and terraced properties. We survey your roof and recommend the best option for your budget.

Do I need planning permission for a loft conversion?

Many loft conversions fall under permitted development and don’t need full planning permission, though dormers on the front elevation, larger volumes and conservation-area homes often do. We check your specific situation early and handle any application on your behalf.

How long does a loft conversion take?

A typical loft conversion takes around 6 to 10 weeks on site, depending on the type and complexity. We give you a clear programme before starting and keep you informed throughout.

How much value does a loft conversion add?

A well-built loft conversion is one of the best ways to add value, often increasing a home’s worth significantly — particularly when it adds a bedroom with an en-suite. It also avoids the cost and stress of moving to a larger property.

Is my loft suitable — will there be enough headroom?

As a rough guide you need around 2.2 to 2.4 metres of height at the ridge for a comfortable conversion, but this varies by roof type and can sometimes be improved with a dormer or by adjusting the structure. Our free survey tells you exactly what’s possible for your loft.

Will the conversion meet building regulations?

Yes. Every loft conversion we build meets current building regulations for structure, fire safety, insulation and escape routes. We work with building control throughout and arrange the final certificate.
