Our story and people

Plehat Ltd was established in the early 2017 by Lauri Lemmenlehti, Mikko Vekkeli and Tuomo Ranto. The founders have experienced careers in various fields of planning and have been entrepreneurs in several companies.

Our first office was located in an old limousine garage in Helsinki.

For a long time it had been a space for architecture student groups and a hatchery for several big-name architecture offices. Today we are located in A-Grid business incubator in Aalto University campus. Plehat has grown to employ seven people and we aim at fast growth. We operate in two divisions: landscape consulting and software development.

What characterizes our office is that our employees have a very broad background in various fields of expertise at a personal level.

We value general education and we draw inspiration for our work from a wide range of cultural backgrounds. We support graduate students in landscape architecture and do basic research on modeling the natural environment in relation to the built environment.

Lauri and Mikko worked as lecturers at the Aalto University Department of Architecture during fall 2017 and spring 2018. The courses explored the combination of landscape architecture and virtual reality experiences. However, it became clear that dividing the attention between education and the company was not good and we decided to focus on growing the company

Environmental planning IT tools have lagged behind other construction sectors due to the relatively small size of the market and the difficulty of modeling the natural environment compared to modeling buildings.

Our most important task is to provide these tools to environmental designers, to improve the quality of design and gradually move towards environmental impact simulations.

Our company’s background is in landscape architecture and we consider environmental design an integral part of our identity.

We do landscape architecture consulting and along with it we offer our broad digital competency. In our team we have brought together considerable part of top digital know-how of the field. We are growing our business consciously to answer the most difficult questions in our field of research.

Our field is extensive and difficult and so our goal is long-term development far in the future.
