The price of residential construction projects will increase on the average by two to three euro per sq m this autumn.

Design and planning of office property will cost 20 to 30 per cent more than work on residential projects, chamber of architects representative Dimitar Mladenov said.

Mladenov took part in a discussion on the problems of the architecture and construction sectors.

New ways to calculate the cost of planning and design services will be introduced in September. Changes are needed to guarantee price uniformity and quality of the product.

In the autumn, the chamber will also publish a list of all companies operating in the sector. Bulgarian design and architecture companies will be able in this way to accept projects from abroad.
