Simple, Smart Loft Conversions from Just £995 + VAT

If you want to unlock extra space in your home without the cost or complexity of a full dormer extension, a Velux loft conversion is one of the most cost-effective and straightforward options available.

​

At Draw Plans, we are specialist architectural designers offering fixed-fee Velux loft conversion plans from £995 + VAT, tailored to meet building regulations and help you achieve planning approval where needed.

Serving London and the Home Counties, we’ve designed hundreds of loft spaces for bedrooms, home offices, studios, and more — and we can help you do the same.

​

What Is a Velux Loft Conversion?

A Velux conversion (also known as a rooflight loft conversion) involves installing Velux roof windows into the existing roof slope without altering the roof's structure. It’s the least disruptive type of loft conversion, perfect for properties with enough existing head height.

​

Unlike dormer or mansard conversions, Velux designs keep your external roofline unchanged — which makes them faster to build, cheaper to plan, and often exempt from planning permission.

​

Benefits of a Velux Loft Conversion

Velux loft conversions offer exceptional value and practicality. Whether you’re creating a new bedroom, office or relaxation zone, this type of conversion comes with multiple advantages.

​

Why Choose a Velux Conversion?

• Cost-effective: Cheaper than dormer or hip-to-gable options

• Minimal disruption: No major structural changes to your roof

• Natural light: Velux windows flood the space with daylight

• Permitted development: Often no planning permission needed

• Quick build time: Less construction time than larger loft extensions

• Clean finish: Retains the original character of your home

• ​

If you have at least 2.2m of headroom at the highest point in your loft, a Velux loft conversion could be the ideal solution.

​

Velux Loft Conversion Ideas & Layout Tips

A successful Velux loft conversion is about more than just adding windows. The right design can turn an empty attic into a warm, functional space that feels like a true extension of your home.

​

Popular Velux Loft Conversion Ideas:

• Loft Bedroom: Add built-in wardrobes, a Juliet balcony, or a compact en-suite.

• Home Office: Use Velux windows with integral blinds to control glare.

• Studio Space: Maximise headroom and storage with custom furniture.

• Hobby Room or Den: Soundproofing and insulation make it comfortable year-round.

​

Layout Tips:

• Use the centre of the loft for circulation where head height is greatest

• Built-in eaves storage makes use of low ceiling areas

• Position the staircase above the existing stairs for efficient flow

• Group plumbing (for en-suites) close to existing soil pipes to save on installation

​

Our expert designers will guide you through your best layout options based on your roof shape, size, and intended use.

​

Planning Permission for Velux Loft Conversions

Most Velux loft conversions fall under permitted development and don’t require planning permission, provided you meet certain criteria:

​

You typically won’t need permission if:

• You’re not altering the roof shape or structure

• Velux windows don’t protrude more than 150mm from the roof surface

• Your home isn’t in a conservation area or listed

​

Regardless of planning rules, Building Regulations approval is mandatory — and our plans are prepared to meet those technical standards.
