There were no other colours they both liked.<\/p>\n<p>That starting point led to a design \u00a0that balanced the raw grey elements; including polished concrete, silvered rough sawn timber and off-grey painted blockwork with varying tones of blue.<\/p>\n<p>Marco explains: &#8220;Although these colours might typically be found in other settings &#8211; for example gallery style concrete floors and faded timber for a coastal feel.<\/p>\n<p>&#8220;Or even quasi-industrial exposed blockwork and saturated blue tones evoking a scholastic environment, the nostalgic origins were not the reason for that design.<\/p><div class=\"gdmag-content-2\" id=\"gdmag-2233433256\" data-cfpa=\"19928\" data-cfpw=\"19928\"><div class=\"gdmag-adlabel\">Advertisements<\/div><!-- code from Primis -

general, it seems people are learning to use colour more boldly in their designs.<\/p>\n<p>Marco adds: &#8220;For a few years now I&#8217;ve noticed that our clients seem to be less afraid of the bolder colours, which was often the case previously.<\/p>\n<p>&#8220;Raw textures also have surged in popularity over the last decade.<\/p><div class=\"gdmag-prop-primary-mpu\" id=\"gdmag-1901277436\"

property.<\/p>\n<p>&#8220;Light ash wood details added a \u2018homely\u2019 warmth with plain white walls and ceilings providing relief, and black fittings acting as a neutral accent.<\/p>\n<p>&#8220;The more domestic-scale detailing of the ash handles and framing, finely patterned blue-grey wall tiles, and intricate profiling on the timber cladding help to balance against the larger scale formats of polished concrete, blockwork and frameless glass.&#8221;<\/p><div class=\"gdmag-prop-in-content-mpu\" id=\"gdmag-888222127\" data-cfpa=\"20294\" data-cfpw=\"20294\"><div

achieved.<\/p>\n<p>&#8220;The clients both love hot weather, the hotter the better, and always wished for a room that could be filled with plants.<\/p>\n<p>&#8220;So, we proposed a frameless glass rooflight along the full length of the extension to flood the space with natural light.<\/p>\n<p>&#8220;The off-white blockwork wall helps to bounce this light into the rest of the

&#8220;Powerfloated concrete was one of the first raw textures I suggested. I showed it to the clients by showing images of various gallery interiors and they instantly fell in love with it.<\/p>\n<p>&#8220;All the other materials essentially &#8216;riffed&#8217; off the concrete.&#8221;<\/p>\n<div id=\"attachment_24708\" style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-24708\" class=\"wp-image-24708 size-full\" src=\"https:\/\/www.granddesignsmagazine.com\/wp-content\/uploads\/2025\/07\/blue-grey-3.jpg\" alt=\"blue grey kitchen with plants \" width=\"640\" height=\"744\" srcset=\"https:\/\/www.granddesignsmagazine.com\/wp-content\/uploads\/2025\/07\/blue-grey-3.jpg 640w, https:\/\/www.granddesignsmagazine.com\/wp-content\/uploads\/2025\/07\/blue-grey-3-250x291.jpg 250w, https:\/\/www.granddesignsmagazine.com\/wp-content\/uploads\/2025\/07\/blue-grey-3-120x140.jpg 120w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><p id=\"caption-attachment-24708\" class=\"wp-caption-text\">Photo: Curtaz Studio<\/p><\/div>\n<h2>Setbacks<\/h2>\n<p>Every renovation project has setbacks but thankfully nothing major was able to curtail this venture.<\/p>\n<p>Marco shares: &#8220;The only cause for concern was the limited palette.<\/p><div class=\"gdmag-prop-in-content-mpu-3\" id=\"gdmag-2480088430\" data-cfpa=\"20294\" data-cfpw=\"20294\"><div class=\"gdmag-adlabel\">Advertisements<\/div><div class=\"GRVMpuWrapper\"><div class=\"GRVAd inline\" data-ad-type=\"mpu\" data-ad-sizes=\"[[300,250]]\" data-ad-refreshmapping=\"always\"><\/div><\/div><\/div><script type=\"text\/javascript\">;new advadsCfpAd( 20294 );<\/script>\n<p>&#8220;This meant that the materials and colours had to be chosen early, so we had less wiggle room that you ordinarily would on a project like this &#8211; especially when it came to the post-tender and cost-saving stage.&#8221;<\/p>\n<h2>Blue paint guide<\/h2>\n<p>Thinking true blue would be a good fit for your interior renovation?<\/p>\n<p>We&#8217;ve rounded up some of our favourite shades of blue on the market right now so you can recreate the look in your own home&#8230;<\/p>\n<h3>1.
