A method, system and apparatus for expandable housing of a mobile communication device are disclosed. A housing of a mobile communication device includes a base layer, at least one of a component layer coupled communicatively on either side of the base layer to enable modification of a modular peripheral component integrated into the housing by sliding the modular peripheral component through a set of grooves located on opposite sides of each of the component layer and the base layer and a holding mechanism in the component layer that enables the modular peripheral component to remain in a fixed position. The modular peripheral component includes a daisy-chainable expansion port that enables an additional modular peripheral component integratable in the mobile communication device to be communicatively coupled with the housing across a variety of physical connections of the daisy-chainable expansion port.
