A couple of years ago I was quite badly burnt by an architect who drew plans for a loft extension. To cut a long story short it cost us thousands on top their fee just to put the loft right in order for it to pass planning. When we decided to have a wrap around extension I was incredibly nervous that we might have another negative experience but how wrong could I be! After receiving several recommendations for Bluelime I reached out to them and arranged for them to come and look at the property. Alton and his team were just amazing, they built an incredible rapport with us, really took the time to understand what we wanted whilst inspiring us with some fantastic suggestions tailored just for us. Everything was delivered on time, plans flew through planning and communication was first class throughout. Unbelievably reasonably priced given the service I received. Cannot recommend enough!

I hired Bluelime Architects to create drawings to convert the ground floor of our house to an open plan layout. Right from the start, Carly at Bluelime gave me an initial call to gather the background information - she was very friendly, helpful and informative regarding planning permissions and building control. Alton then came around for the site visit - he was very friendly and professional and provided very useful practical feedback on our plans. The drawings were accurately prepared quickly within a week and when I requested some changes they were promptly updated. Even following completion of the work, Carly made a point to reach out to offer any help and advice required which was much appreciated. Thank you very much to the team at Bluelime for their support!

The team at Bluelime were incredibly helpful and I’m really happy with the outcome of my loft conversation and new kitchen. This was my first big building project so it was amazing to have Carly and Alton guide me through the process. I’d definitely recommend them for any big structural work.

We used Bluelime for a ground floor extension and garage conversion, they gained us planning consent first time and came up with a great layout, we then used there in house structural engineer and after receiving several costs from other firms … went with them through the build. They were helpful and efficient throughout the costs agreed on were stuck to, when we did deviate a little from the plan they gave us written confirmation of every cost increase and every cost decrease. The project ran to time and budget and we are so happy with our new space, would highly recommend !

We worked with Alton and Carly to get through the whole Planning process including their recommended structural engineer and party wall surveyor. We wanted on a side + rear extension and their experience of working in our borough (Enfield) made this process go very smoothly and their expertise made us feel comfortable from day one. They produced initial plans quickly, made revisions quickly and were a pleasure to work with throughout. Now that the build has started they have been very conscientious in responding to follow-up questions from our builder. Would recommend working with them on any similar project!
