During the design process, detailing was also developed to allow features such as the projecting window frames to be realised in accordance with the original design. <\/p><p data-start=\"1744\" data-end=\"2097\">At the early stages of the project, mock-up areas were built and several colour and workmanship samples were reviewed to ensure that the final result would correspond as closely as possible to the building\u2019s original appearance. The Postitalo fa\u00e7ade also features distinctive characteristics typical of the building, such as two different tile sizes, a varied bond pattern and a lively colour palette that reflects the original. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-88ecd96 elementor-widget elementor-widget-heading\" data-id=\"88ecd96\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">The tolerances of the old building presented their own challenges for the implementation<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-503028f elementor-widget elementor-widget-text-editor\" data-id=\"503028f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p data-start=\"2174\" data-end=\"2413\">Pietil\u00e4inen describes the adaptation of the new system to the old building as one of the most technically demanding aspects of the project. The millimetre-precise panel system had to align with the preserved granite window reveals, where tolerances were in some places several centimetres. <\/p>\n<p data-start=\"2415\" data-end=\"2699\">This was precisely where the flexibility of the system proved to be an important advantage. As Pietil\u00e4inen points out, the clinker tile layout could be fine-tuned so that junctions and joints could be made to suit the overall appearance, even in challenging areas. Practical solutions for different types of joints were also found on site.  <\/p>\n<p data-start=\"2701\" data-end=\"2948\">Another successful implementation method was to attach the L-shaped corner tiles for external corners only on site. This allowed the straightness and precise dimensions of the external corners to be verified in place. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-ad332f2 e-grid e-con-full e-con e-child\" data-id=\"ad332f2\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-18a7f6e elementor-widget elementor-widget-image\" data-id=\"18a7f6e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-jarjestelman-arkkitehtoniset-mahdollisuudet_1-e1777284061991.jpg\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"BRIX-jarjestelman-arkkitehtoniset-mahdollisuudet_1\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6MTQ4NjAsInVybCI6Imh0dHBzOlwvXC9icml4LmZpXC93cC1jb250ZW50XC91cGxvYWRzXC8yMDI2XC8wNFwvQlJJWC1qYXJqZXN0ZWxtYW4tYXJra2l0ZWh0b25pc2V0LW1haGRvbGxpc3V1ZGV0XzEtZTE3NzcyODQwNjE5OTEuanBnIn0%3D\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"800\" height=\"791\" src=\"https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-jarjestelman-arkkitehtoniset-mahdollisuudet_1-1024x1013.jpg\" class=\"attachment-large size-large wp-image-14860\" alt=\"\" srcset=\"https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-jarjestelman-arkkitehtoniset-mahdollisuudet_1-1024x1013.jpg 1024w, https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-jarjestelman-arkkitehtoniset-mahdollisuudet_1-300x297.jpg 300w, https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-jarjestelman-arkkitehtoniset-mahdollisuudet_1-768x760.jpg 768w, https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-jarjestelman-arkkitehtoniset-mahdollisuudet_1-1536x1520.jpg 1536w, https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-jarjestelman-arkkitehtoniset-mahdollisuudet_1.jpg 1750w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ffae337 elementor-widget elementor-widget-image\" data-id=\"ffae337\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-Helsingin-Paapostitalo-scaled-e1777284087912.jpg\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"default\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6MTQ4NjIsInVybCI6Imh0dHBzOlwvXC9icml4LmZpXC93cC1jb250ZW50XC91cGxvYWRzXC8yMDI2XC8wNFwvQlJJWC1IZWxzaW5naW4tUGFhcG9zdGl0YWxvLXNjYWxlZC1lMTc3NzI4NDA4NzkxMi5qcGcifQ%3D%3D\">\n\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-Helsingin-Paapostitalo-1024x768.jpg\" class=\"attachment-large size-large wp-image-14862\" alt=\"\" srcset=\"https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-Helsingin-Paapostitalo-1024x768.jpg 1024w, https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-Helsingin-Paapostitalo-300x225.jpg 300w, https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-Helsingin-Paapostitalo-768x576.jpg 768w, https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-Helsingin-Paapostitalo-1536x1152.jpg 1536w, https:\/\/brix.fi\/wp-content\/uploads\/2026\/04\/BRIX-Helsingin-Paapostitalo-scaled.jpg 2048w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-af35e42 elementor-widget elementor-widget-heading\" data-id=\"af35e42\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">A successful result also required careful installation work<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ceddfdb elementor-widget elementor-widget-text-editor\" data-id=\"ceddfdb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p data-start=\"3012\" data-end=\"3291\">Pietil\u00e4inen also gives credit to the installers, who carefully carried out the complex substructures around approximately 400 windows.
