I am from Algeria. Honestly I can't judge the Saudi Marketplace because I don't know it. But let's be clear about it. If you think that interior design is an easy skill than you don't get it at all. Interior designers cannot remember a 1000 pages book of standards and no can do so. Interior designers skill is truly about putting the right design with best technical knowledge and interior designers know almost a lot about materials that normal people cannot easily grasp and if you think internet will help you about it you're also wrong because materials are now more about marketing than telling the truth. At the end in one sentence, interior designers sell you knowledge + true experience.

عزيزي مش غلط نقتبس .. وهذا مش التصميم كامل هذا يسمى تخطيط فقط تراعي فيه ستاندرد عالمي يبين لك احجام قطع الأثاث والحد الأدنى للمسافات .. لو فرضنا انك عملت نفس التخطيط من الكتاب ولكن تشطيبات سيئة وإضاءة غير مدروسة ما استفدنا شي .. المصمم ياخد مبلغ كبير ولكن يعطيك تصور واقعي ويغنيك عن تكاليف التعديل بعد التنفيذ لتصميم غير مدروس .
