A kit (100) for erecting a polygonal reinforced enclosure in situ is disclosed. The aforesaid kit comprises: (a) a framework (110) defining overall enclosure dimensions and having open flank areas; the frame (110) provided with securing means; and (b) a plurality of reinforcement members (120) being securable within the frame (110) by means of the securing means. The kit (100) further comprises a plurality of panels (140) configured to overcast the flank area. The panels (140) are securable to the reinforcement members (120). A volume defined by the framework (110) and the panels (140) is fillable with a filler for solidifying said enclosure.

A watchtower (100) useable as a secure shelter for at least one observer is disclosed. The aforesaid watchtower (100) comprises (a) a base (130)placeable on the ground; (b) a body vertically erected onto the base; the body is formed by a plurality of substantially hollow members (110, 112) placed one upon the other; (c) an observer's compartment (120) crowning the body; and (d) means (115) for mechanically interconnecting said base, substantially hollow members (110, 112) and observer's compartment (120) therebetween. The means (115) is configured for releasably interconnecting the base (130), substantially hollow members (110, 112) and observer's compartment (120) therebetween such that the erected watchtower (100) is demountable in sections.

A blast protected unit (100) for blast protection comprises: a protecting panel (14) having a first side (7) and a second side (8); a sub-frame (16) adapted to circumscribe said protecting panel (14); and a plurality of energy absorption units (30). The absorption units (30) are adapted to connect the sub-frame (16) to the protecting panel (14). Each of the energy absorption units (30) is connectable to the protecting panel (14) and the sub-frame (16), such that the aforementioned blast protected unit (100) is formed. The energy absorption units (30) are configured to deform under a blast force applied against the first side (7) of the protecting panel (14), allowing the protecting panel (14) to move away from and remain in proximity to the sub-frame (16). The blast protected unit (100) is adapted to be connected to a building structure, such that a protection from blasts is provided to the internal portion of said building structure, the internal portion being located at the second side (8) of the protecting panel (14).
