Hey, this is exactly the kind of service I can help you with. I have been running Emma Victoria Interior Design for 10 years. You may have seen me in my branded black, white and yellow mini! We specialise in residential interior design advice and renovations in the South West London area. Our bread and butter is Victorian terraces.
As this is not a third party recommend I'd be happy to put you in touch with recent clients from the area who have used us, we also have third party reviews on google you can check out.
Have a look at what we have done and how we work: www.emmavictoria-id.com
we have different packages for different budgets.
Hope we can help.
