Window manufacturer Velux says the next stage in its “teddy bear” TV advertising campaign will create business for architects who use room in the roof designs.

The same special effects team which worked on the Harry Potter films helped produce the new ad, which features the Velux teddy meeting and falling in love with “girl teddy” in an adjoining loft.

The ad campaign will start on terrestrial and satellite channels and in cinemas across the UK and Ireland over the coming months.

A Velux spokesperson said: ” The advert will help boost business for architects as it communicates the benefits of living in a home with ‘room in the roof’ to their clients.”
