The prototype recreation park in Agios Thomas, Maroussi, is designed to meet the most modern urban development and ecological standards, replacing an area with abandoned buildings which was converted into an informal waste disposal site.

The project includes earthworks, demolition, road construction, utility networks, installation of electrical facilities (lighting, switchboard, grounding, etc.), irrigation and stormwater drainage construction, botanical study (plant locations, species, sizes), geometric design in accordance with the Road Works Design Guidelines for bike paths, sidewalks, roads, etc., as well as connecting the project to the utility networks of the area.

The ongoing development of the Glyfada beachfront involves the creation of a 5-km path for walking and cycling. Extensive planting of large and small trees is being carried out as part of the project, along with further upgrading of infrastructure for swimmers at the blue-flag awarded beaches.

The pedestrian walkway along the beach from Agios Kosmas to Asteria is being completed with additional paths planned for the arms of the fourth marina. The construction of the bicycle lane, facilities for sports, culture, and recreation, as well as the creation of a large number of parking spaces, contributes to an inclusive public space, open to citizens and visitors.

The project upgrades the 25th of March Square, located in the Meladeza area of the Municipal Community of Vari, to create a sustainable recreation space for citizens.

The previous appearance of the square, covering an area of approximately 6 acres, was a dirt field, with an abandoned poultry farm in the northern part and an olive grove in the south. Specifically, the following interventions are carried out: construction of green spaces with fitness equipment, tree planting around the square, installation of a green irrigation system, creation of a playground, construction of sunken green beds along the southern entrance of the square for the full utilization of rainwater, installation of lighting poles, construction of floor-level sculptural compositions, and the formation of a space for the future installation of a refreshment stand and cafeteria, preserving the existing olive grove.

The first bioclimatic traffic education park in the Municipality of Glyfada, created for children and adults, is located in a lush green area in the Karvela district. It represents an intervention in a city known for its innovation and child-centric design.

The modern city block, enclosed by Epaminonda-Ifestou-Dimela-Poseidonos streets, simulates a road network with traffic lights, crosswalks, and basic traffic signs. Children learn in an experiential, simple, and understandable way how to navigate through a miniature environment of a real city, both as conscientious drivers and cautious pedestrians. The space is designed with numerous green corners (trees, shrubs, flowers) and spacious wooden tables with integrated benches, where parents or guardians can spend their time pleasantly, without ever losing sight of the children. The prototype space, built to the highest construction standards and featuring hundreds of new trees and plants, becomes a safe playground with state-of-the-art lighting, large sidewalks, and surfaces in bioclimatic materials.

The Contemporary Bioclimatic Park is a new communal recreational area spanning 10 acres of public land previously occupied by the Korydallos Detention Center.

Its central feature is a water surface covering approximately 1,500 m², accompanied by an underground pumping station for water management. A network of pathways traverses the park and the water surface, organizing sports facilities, recreational areas, and gathering spaces. Specifically, a 5×5 court, two large playgrounds for different age groups, including facilities friendly to people with disabilities, and a large metal structure with a retractable awning over a gathering area have been created. Wooden pergolas are placed on the water surface and alongside the 5×5 court. The area is covered with grass and a large number of shrubs and trees, covering about 40% of the park’s total surface. Environmentally friendly materials and methods were used in the construction process.

The project involves the restoration or new construction of sidewalks in road sections and communal areas of the Municipality of Glyfada, for facilitating sustainable mobility and promoting urban resilience. The main objective is to serve the citizens, ensure safe passage for pedestrians and vehicles, and enhance and beautify the city’s sidewalks.

The project involves the redevelopment of sidewalks, regulation and shaping of pedestrian pathways, parking areas, and green spaces with the goal of their qualitative and functional enhancement. Additionally, this study includes the construction of sidewalks at the newly established Glyfada Cemetery, where internal pedestrian pathways are also configured for circulation.

The project involves the energy-efficient, functional, and aesthetic upgrade of Metamorfoseos Square and its adjacent streets, introducing bioclimatic characteristics.

The intervention area covers 6.7 acres, with 2,200  m² occupied by the central square and 4,500  m² by the adjacent streets and sidewalks (Knossou, Korinthou, Thermopylon). The square extends into a larger, unified surface, incorporating green spaces with public seating and an upgraded playground. The seating areas of adjacent businesses are delineated, allowing the creation of a free lane for the unimpeded movement of emergency vehicles. The entire area is redesigned with modern accessibility infrastructure for people with disabilities.

The architectural goal of the redevelopment of the New Cemetery of Glyfada is to create a space where the natural environment remains prevalent, while the final impression and appearance do not resemble the usual image of Greek cemeteries, where marble and hard surfaces dominate.

The project started in late 2014 when a special law granted an area of ​​42 acres for the construction of a new cemetery within the premises of the Hellenic Air Force installations in Ano Glyfada, where the Telecommunications and Electronic Media Factory (ETEM) has been housed for decades. The burial areas in most of the cemetery do not consist of visible grave formations but are covered within larger units that follow the slope of the terrain while maintaining the character of natural landscaping. In total, more than 1,000 trees were planted, while the Municipality of Glyfada concurrently constructed a new perimeter road with lighting and fencing, as well as the necessary hydraulic works for the drainage of rainwater from the cemetery.

The project involves landscape architecture for the stabilization and environmental restoration of the embankments along the Diakopto railway line in the Peloponnese, with botanical works being carried out between the Vouraikos River bridge and Rododafni to enhance their aesthetics and functionality.

The scope of the contract includes the execution of botanical works and constructions aimed at protecting the embankments from erosion, stabilizing them to prevent imminent erosive phenomena, concurrently restoring their environment from the damage caused to the landscape due to the construction of the railway line. Clearing of weeds is carried out along the entire footprint of the line from Kiato to Rododafni, while the embankments of the Diakopto-Rododafni section are cleared and vegetated during the fire prevention months.

The project involves the construction of seven new children’s parks in Kythira, in the areas of Diakofti, Kalamo, Keramoto, Livadi, Logothetianika, Mitata, and Friligianika, where certified and safe equipment is installed. The project has a total budget of € 240,000, of which € 204,000 is covered by the “Philodimos” program of the Ministry of the Interior

The new “Andreas Papadimitriou” Square, covering an area of ​​approximately five acres, was transformed from an undeveloped area into a natural space of recreation for the residents of Moschato, near the beach. The square was designed and constructed with the aim of achieving lower carbon emissions, zero energy consumption, and improving the microclimate. This was achieved with the use of bioclimatic paving materials, water-permeable flooring, increased shading and green surfaces, reduced energy consumption for lighting, and limited use of irrigation water.

During the regeneration of the square, a children’s playground was created with suitable flooring and modern equipment, a communal relaxation area with a shelter and a paved area for events, an outdoor exercise area with gym equipment, and walking paths, both along perimeter and in the interior. As part of the overall regeneration of the neighborhood, a section of Athanasiou Diakou street was pedestrianized, the area was configured for full and safe access by people with disabilities, greenery was enhanced with tree and shrub planting, benches and other urban equipment, low-consumption LED lights and bollard lighting were installed, and additional plumbing works were carried out.

The Armed Forces Park, located in the municipal community of Tavros, covers an area of fifty-three acres. To the east, it fronts onto Konstantioupoleos Ave., while to the north and northeast it borders on Plot 153A, which houses residences for the Ministry of National Defense personnel. To the south and southwest, adjacent to the entrance on Eirinis Ave, the park is flanked by residential areas and a beverage industry. To the west, it borders on military pharmaceutical warehouses and an open parking area for heavy vehicles. Its uses include a Traffic Education Park, open-air cinema, cafeteria, playground, and a refreshment stand. The park is open to visitors daily, with access from both entrances on Konstantinoupoleos Avenue. The northern entrance, although equipped with parking space, is open only to pedestrians. The southern and central entrances have parking space and are next to the open-air cinema, which attracts many visitors during the summer months.

The park is the only green space of such size for the residents of the Municipality of Moschato-Tavros; even on a metropolitan level, the only green area of similar size in close proximity is Philopappou Hill in Koukaki, Athens. Therefore, the park attracts many visitors from surrounding districts, including schools that visit the Traffic Education Park, while many people come on a daily basis for cycling or walking. Residents of Tavros enter the park from the secondary entrance, on Eirinis Ave., while the entrance from Samou Street remains closed and is mainly used by municipal maintenance vehicles.

As part of the overall upgrade of the park, all railings are replaced, and a new metal fence is installed on the existing cement wall along Konstantinoupoleos Ave. The ground is covered with gardening soil, with local groundwork amendments for reaching the desired height. New paths and flowerbeds are designed throughout, and the existing cable network is buried, accommodating new 3m-high lighting poles along the pathways. The new underground power supply network additionally supports the pumping station and the open air cinema. The interior of the playground is reconfigured with safety rubber floors, modern equipment, pergolas, and three different types of seating. The walking surfaces are covered with porous, compacted processed soil, pebbles or gravel, and bark, while wooden curbs are constructed in the planting beds. Signage is upgraded with metal signs for guidance and navigation.

The lighthouse is located on the southern side of Salamina, in Kochi or Kokki, between the resorts of Peristeria and Kolones. The complex was constructed in the early 20th century and first operated in 1901. It consists of a 134.75 m² building, with an 11m-high tower located in the center, crowned by a metal cage. The lighthouse had suffered extensive damage due to the age of the building, lack of maintenance, and its proximity to the sea.

The restoration is based on three principles: respecting and highlighting the typological and morphological characteristics of the listed building, ensuring the monument’s durability over time, and facilitating the possibility of its reuse. In this direction, construction and electromechanical restoration works of the lighthouse were carried out, including the upgrade of the surrounding area; connection to the power grid was provided anew, and signs were installed, while print and electronic material was created for information and publicity regarding the monument.

The project involves the modernization and maintenance of the historic indoor gymnasium of Piraeus, known as the “Petros Kapagerof” or “Papastreteio,” marking the largest sports endeavor in Piraeus after the Peace and Friendship Stadium.

The physical scope of the project includes an indoor gymnasium featuring a court suitable for basketball, volleyball, handball, and futsal matches, a competitive area for rhythmic gymnastics, permanent stands on both sides of the court with a capacity of 1,500 spectators including distinct VIP and press areas, auxiliary facilities catering to athletes, coaches, referees, medical support staff, administrative offices, training rooms, and press rooms, as well as audience service areas, storage spaces, and mechanical rooms. The gymnasium facilities not only accommodate accessibility but also enable use for sports events for people with disabilities.

This project complements and completes the integrated management of urban sewage in Spetses, including collection, transport, treatment, and disposal. This need arose during the construction of the sewage pipeline in the area of ​​the Ancient Baths, where antiquities were found, so the pipeline could not be constructed at the depths specified in the project study. Therefore, in the context of finding alternative solutions, taking into account the slopes of the area, the excavation depths, the limited space for work execution, and the possibility of draining adjacent properties, the Service deemed the construction of this network segment as a suction network as the most suitable solution.

The relevant construction works of the remaining network include the construction of gravity sewer pipes from structured wall plastic pipes in open trench, with a total length of 19,245.00 m; the construction of pressure sewer pipes from polyethylene segments in open trench, with a total length of 970.00 m; the construction of inspection chambers using precast concrete circular manholes, totaling 637 pieces; the construction of inspection chambers using precast synthetic material manholes, totaling 44 pieces; and the construction of a vacuum sewer network, including the preparation of its implementation study.

The adjustment of the Acharnes stream (Kanapitsa) is undertaken for a length of 12.6 km, from its outfall to the Kifissos river, M.P. 0+000, to M.P. 12+586 in the area of Thrakomakedones and Acharnes, on the southern slopes of Mount Parnitha. This is an important flood protection project, given the frequent occurrences in the area.

The works include the adjustment of the natural bed of the stream in sections, with an open cross-section using wire gabions at a total length of approximately 7.5 km; a closed box culvert is planned for a total length of 2.3 km, of which 1 km concerns existing drains. No interventions are proposed in the protected areas of Mount Parnitha, where the natural cross-section is preserved unchanged.

The project involves the restoration of the landfill (Solid Waste Disposal Site) at the location of Lachni, in Kythira, to comply with current environmental standards. The process unfolds in two phases, each contributing to the overall goals of the project.

The first phase involves technical interventions for the restoration of the landfill, including earthworks for systematic waste collection, terrain shaping and leveling, final cover works, stormwater management, drainage, and biogas management, along with landscaping and irrigation works for landscape reclamation.

The second phase focuses on the construction of solid waste landfills in Kythira and smaller landfills in Antikythira. Key activities include earthworks for site shaping, waterproofing, and addressing environmental impacts. Supporting infrastructure works are developed for the Kythira landfill, including appropriate slopes for stability and optimizing the space capacity. The waterproofing system consists of a geological barrier, rear layer, waterproofing membrane, geosynthetic drainage layer, geotextile, and protective gravel material. Drainage systems are connected to settling tanks for effective waste management. This phase also includes the fencing of the construction site, road access network construction, installation of lighting network, administration buildings, creation of irrigation tanks, fire infrastructure, water supply systems, metal workshop building, fire protection zone planning, creation of a biogas management system, firefighting network, flood trenches, and environmental monitoring initiatives.

The new seawall, measuring 110 m in length, is replacing the former western seawall, which suffered irreversible damages, including collapse along a section. With a useful depth of at least 3 m, the seawall is constructed to serve pleasure boats up to 15 m in length at the port of Poros.

The project involves the construction of flood management works in three streams in the city of Loutraki -Katounistra, Prathi, and Kareli- to address past flooding issues. The works include channel excavation, local investments, outlet works, construction of sediment retention structures, as well as the necessary technical works of open and closed rectangular cross-sections at their most significant points and intersections with major roads.

Works on the Katounistra stream include channel management works from M.P. 0+000 to   5+492.1, technical works for road crossings of the stream, sediment retention structures, and outlet works with concrete bed and protection with boulders. In the Prathi stream, channel management works from M.P. 0+082 to M.P. 7+544.2, technical works for road crossings of the stream, sediment retention structures, and outlet works with concrete bed and protection with boulders are included. In the Kareli stream, channel management works from M.P. 0+000 to M.P. 0+700.8, technical works for road crossings of the stream, sediment retention structures, and outlet works with limited intervention with wire gabions to shape the junction of the Kareli stream with the Prathi stream are included. Additionally, channel management works, and their accompanying structures are constructed in the Katounistra stream over a length of 5,492.10 m, in the Prathi stream over a length of 7,462.20 m, and in the Kareli stream over a length of 700.80 m.

The project involves the maintenance and improvement of roads in the Municipality of Salamina, including the maintenance of existing asphalt pavement and primarily the removal and construction of asphalt wearing courses for traffic. Maintenance works aim solely at restoring damages and defects or generally returning the roads to their original condition, rather than fundamentally modifying their characteristics.

Concrete-paved road reconstruction works are carried out in the area of Kanakia, where the complete reconstruction of the pavement is planned on 28is Oktovriou Street, as well as in the broader area of Aianteio. Regulatory signs R-2 (STOP) are installed at road accesses perpendicular to priority roads of the main network: Faneromenis Avenue, Vasilikon Avenue, Peristerion Avenue, Dimokratias Avenue (Narrow), Resti Avenue, Aianteio Avenue, Kaki Vigla Avenue, Salamina Avenue, etc. Additionally, signs indicating dangerous locations are installed on the same streets.
