About Us

Apxe Architectural Studio creates state-of-the-art buildings, paragons in architecture and engineering built with exceptional quality and having unique comfort of habitation.

Apxe has been established in May 2007 by arch. Georgi Nikolov with main activity in the field of architectural design and project management of construction.

The main goal and pursuit of the studio is to take construction to a higher level via sustainability, energy efficiency, wise project management and craftsmanship, leading to great comfort and aesthetics.

Well established with long years of experience our studio has won recognition as a pioneer in our country in the field of implementing the ‘passive house’ standard with a series of projects, in the beginning with single-family houses, continued with large-scale and non-residential buildings.

The advantages distinguishing Apxe are concentrated mainly in the following directions:

  • High-quality and detailed design including adherence to ‘passive house’ and net zero-energy standards;
  • Project management of construction;
  • Predictability and optimization of the construction budget;


The studio offers deep detailed research of the design works in order to attain highest investment efficiency of the building initiative. Our architectural design delivers high quality professional approach and consistency to the smallest detail. Thus we provide an exceptional and unique product, with high technologies and innovative solutions.

We are convinced that the holistic approach in the design process leads to results of highest quality. For this reason, the studio includes the whole team of engineers on an early stage of the design process and continues with this interdisciplinary working model until the completion of the building execution. The engineers in our team have proven high professional qualification and experience.


Georgi Nikolov is the first Bulgarian architect – Certified European Passivhaus Designer by Passivhaus Institut – Dr. Wolfgang Feist, Darmstadt, Germany.

Construction management

The studio manages the project up until obtaining permission for use of the building. Thus, our team performs all principal organizational functions during implementation: elaborates detailed time construction schedule and controls its observance, assures tendering and right choice of construction companies together with the Investor, coordinates the work of the subcontractors, executes daily supervision on site and bears responsibility till the end of the construction phase. Our experience shows that for achieving high-quality results in implementing the design into construction, every project should have a strong leader. In its work Apxe has proven to be the right project manager.

Predictability and optimization of the budget

Each investor in the field of construction should have the opportunity to plan the project budget steadily and to control it strictly during the construction process – from the first steps of the design process till the successful execution. In this process, we apply our abundant experience and know-how in the local construction market. Due to the experience gained as a project manager of a series completed projects, Apxe could design and budget at the same time, thus corresponding precisely to the client’s task, also not exceeding the desired total investment costs of the project. Optimization of the construction costs, never compromising the quality, is the precondition for successful execution without contingent expenses.
