I can recommend local architect Jim Hutcheson of RALA which hesitation.

You could try Atelierdb - a practice based in Earlsfield that really listened to what I wanted and took into account all of my requests/needs. They've just submitted plans for my loft/side return extension, which have been approved (yay)! Good luck - http://www.atelierdb.com

Hi all

We're about to undertake a house project and would love recommendations for a creative and thoughtful architect. This is going to be our forever home so really want to think it all through (having learnt a few lessons from previous projects) so would like to work with an expert to help us answer the right questions and suggest new ideas. Anyone know anyone?

Thank you!
