The municipality expands over 4 km either in north-south and east-west direction and covers an area of 14.85 square kilometres (5.73 sq mi).

In the area of the watershed between the Mur and Raab lies the gradual transition between central and eastern European climate.

[5] An indication of the course of the brook in a clearing area also includes the derivation of "*laz/6nica" to "lazъ" "grubbing, repented, bright patch in the forest".

In the 16th century large parts of today's municipal area were incorporated by the Baden contract[clarification needed] or by inheritance into the German Order.

Due to the easy accessibility Dr. Huber from Graz decided to build a guesthouse and several villas in Laßnitzhöhe for recovery of guests during summertime.

In 2002 the Trachtenkapelle Laßnitzhöhe looked back on 50 years since its foundation, which was celebrated with the blessing of the flag for the local chapel.

In 2010 a building was built there with apartments with underground parking and restaurant and space for a new village hall and the local Raiffeisen bank and several shops.

On a plot of land next to the main square provided by Eduard Miglitz on 13 August 1961 the foundation stone was laid for the church designed by the architect Robert Kramreiter-Klein.

The facilities of the church include the Cross of Christ the King by Othmar Klemencics and the glass paintings of the Baptistery by Rudolf Szyszkowitz.
