Nick Woodworth launched Qualitas Construction in 2005, with a vision to provide premium quality extensions and refurbishments in south west London.

In 2007, alongside Jonathan Woodcock, an experienced architect, he set up Pure Basements to accommodate the growing trend for basement conversions.

They have worked hard to gain a reputation for design, quality, professionalism and integrity on their building projects. The two companies have now merged to offer a one-stop shop for all your construction and design requirements.

Qualitas undertakes the following building works:

■  Single-storey extensions
■  Double-storey extensions
■  Basement conversions
■  Loft extensions
■  New build houses
■  Architectural services
■  Interior design, decoration and fitting
■  Landscaping
