Design an architectural drawing of a dream home, capturing a photorealistic and cinematic composition with ultra-realistic, high detail visuals. The scene should feature cinematic lighting and depth of field to enhance its hyper-detailed presentation. The home's structure should be beautifully color-coded, displayed in 8k resolution, set against the backdrop of a sunny day. Embellish the landscape with many intricate details, such as lush gardens, flowing water features, and elegant outdoor living spaces, while ensuring the core concept of a luxurious and dreamlike residence is maintained.
