First Penthouse is a niche rooftop development company, that work with property owners to turn under-utilised rooftop spaces from potential liabilities into valuable assets.


The company was founded in 1992 by Håkan and Annika Olsson, two highly qualified Swedish property developers with a background in developing advanced and innovative construction techniques.

Using high-tech site preparation methods and advanced pre-fabrication of penthouse modules off site, occupiers are not inconvenienced by disruption and disturbance normally associated with projects of this nature. Modules for a typical penthouse are installed wind and water tight, with fixtures and fittings and all services connected in one day.

We work as developers, turn-key contractors, module suppliers and project managers. Our expertise will guarantee that the transformation of your roof top, from the conception of an idea to practical completion, is a smooth and efficient process.
