We provide a wide field of architecture services, both in renovation and newly built projects as well as interior design concepts. Our sectors include public buildings, residential projects, urban design and commercial refurbishments. Schools and daycare centres have been the main focus for us in the public building sector. Residential projects vary from unique private homes and villas to apartment buildings and senior homes. We have a lot of experience in the healthcare sector in the commercial side.
