Turn your critical eye on your existing furniture and decide which ones can be given an upgrade. For a vintage look, all you need is to give them a fresh coat of paint in a distressed style, change of fabric and stuffing. For example, a contemporary steel dining table with a glass top can be give a royal change. Paint the steel in a dull rose gold and seal it with a matte top coat. Then place an embroidered fabric under the glass top and fix it. Place the glass top and your vintage dining table is done.
Books, books and more books
Nothing speaks more Victorian than a good-sized library. Sadly, with space constraints, making a separate library is out of question. To get that feel though, all you must do is allocate a spare wall for your precious books. Get a carpenter to build shelves along the whole wall. Then stack all your books together with a few knickknacks and photographs thrown in. Your me-time corner is ready.
