Deeply disappointing. Errors with architectural drawings. Mistakes with mapping of pipes. Excrutiatingly slow replies when we need corrections.
In the first phase of our works (loft extension), we were able to just about get away with some of the things Resi didn't get right, but during the second phase of work (rear extension) this has become a real problem. Incorrect drawings have meant delays as we have to suddenly get new party wall agreements because we're closer to our neighbours than expected. This means delays. Incorrect pipe mapping means we're having to pay the engineers AGAIN to redraw the design of the foundations for ground floor. This also means delays. And all of this is costing us thousands in additional costs as along with new engineering drawings, we're also still paying for a skip that we can't use whilst all works are paused. We don't have heating. Our back wall is missing. A tarpaulin covers most of the garden. And it seems they've simply not bothered to reply to the engineer emails sent at the start of this week. I'm deeply frustrated and have gone from thinking Resi was a decent (but not inexpensive) way to do these kind of works and find good builders, to wanting to warn people away. Such a shame.

Both Jack and Catherine were very responsive and helpful in getting my planning permission quickly. Jack helped me think through the best solutions and Catherine liaised closely with the planning authority. Thanks both!

This is our first time planning an extension, and Resi have been invaluable at helping us to ensure everything is planned, and lined up ready to go. The builders they put us in touch with have been really professional, and the platform is also very helpful to keep track of all the key documents.

Planning approval granted for our home extension! Huge thanks to the whole Resi team for their support, expertise and responsiveness throughout the project.
Before starting this I had absolutely no idea how much work – and how many stakeholders – are involved before you even get to the build stage. The Resi team made the whole process much clearer and far less stressful from day one.
A special mention to Heather, who answered all our questions and gave us the confidence that Resi was the right partner to help us navigate the council and planning process. She played a big part in us deciding to go ahead with Resi.
A special thank you as well to Ulker (the most patient architect with our many changes of heart), Jack from Resi Connect, Kavek our account manager, Danielle who guided us through planning, and Andrew who somehow manages to send helpful emails even on Sundays.
The platform itself is excellent and very easy to use. Everything is in one place — tenders, drawings, key documents, uploads etc. — so there’s no digging through endless email threads. The shared inbox also makes it really easy to keep everyone aligned, including my partner.
Resi Connect is another really useful feature, giving access to vetted partners and specialists which saved a lot of time trying to find trustworthy professionals ourselves.
When we first researched options for our extension design and planning drawings, Resi weren’t the cheapest (though definitely not expensive either), but in hindsight they’re genuinely great value for the level of support you get. Having experienced professionals available to guide you through planning permission, technical drawings and all the steps before building starts makes a huge difference.
Resi are a fantastic partner to have — with the architectural expertise, planning knowledge and network you need to navigate the process confidently.
A genuinely great team to work with and we’re very grateful for all the help along the way. If we ever do another extension project, I’d happily work with Resi again.

I'm a super busy Father of 3 and very time poor!
Resi have been so helpful in educating me how to budget, understand how renovations work and getting back to me on all my questions, concerns and managing expectations along the way.
I'm celebrating successfully getting my planning permission which feels like a huge milestone to achieve!! There is still a long way to go, but I know I have Resi to support me, which gives me so much comfort.
Shout out to Ines, Ted and Danielle who have got us to this stage.
I must however give a special shout out to Andrew - who has literally been counselling me along this journey, making time on a late Fridays to talk and I know he genuinely cares about the outcome of this project and how much it means to me and my family. I'd be lost without him. Thank you Andrew.

Carleton at Resi has produced drawings for the purpose of obtaining planning approval. I am very pleased with the design. It was easy to work with Carleton, as he was very responsive to my ideas and concerns. I felt he was bringing a lot of expertise to bear on my design, and he was friendly and patient. I am very pleased with the service provided by Resi, and I will continue to work with Resi towards construction of my extension.

I have been engaged with Jamie over the past 8 months with regards to a loft conversion in the Borough of Richmond. Jamie was superb throughout - offering up countless calls and intros across the business. Of particular use was a call with Jack from the planning team. I would highly recommend Resi, they are prepared to think outside the box, guide you through challenging designs and local planning regulations and most importantly they are very personable.

Reply from Resi
Resi helped and guided us through what turned out to be a fairly simple planning and design process and helped us gain the Council planning permission we needed successfully. Highly recommend this group for your next extention.

I was slightly skeptical about the 'online' approach but I have been extremely impressed by our interactions with the team, their efficiency, amazing local knowledge and thrilled with the positive outcome. I would thoroughly recommend them and they are a far more cost effective solution than the alternatives.

From start to finish of our project RESI has been there with us, advising, suggesting, supporting.
Their professionalism and technical knowledge is superb.
Our architect, Pedro was a great communicator. We had limited house footprint to play with and we wanted a lot! Pedro's greatest asset beyond his imagination and technical expertise was that he listened to our wishes and our ideas taking them on, both creative and practical. We were losing garage storage space in the re-build, but Pedro has found room to replace quite a bit of that. We are now in the house and are daily pleased with the quality space that has been created; friends, family and importantly, neighbours, are very impressed with what has been achieved. And our builder was also very impressed with how Pedro used the space available. We have gone from having the worst house in the street to one of the best!
We wanted the build to be as eco-friendly as possible and include heat pump, solar panels and battery. RESI worked with us on this. Ben in particular was very helpful sounding board, and his detailed building regs drawings were very helpful in getting our 1970s house as efficient as possible.
RESI were a great in helping us find a builder. There was no pressure to select one of those builders and the advice we got was impressive. The builder we used actually was a RESI builder and we were not disappointed. The contract support we had from Sam – his thorough assessment of quotes, attention to detail and then ensuring the contract was fit for purpose was incredibly helpful.
We project managed our build with the timely assistance of Ben in helping us make our decisions, guiding our responses to the builder's questions. His technical knowledge and ability to communicate that in plain English was invaluable. This post design support was incredibly impressive; I really don't think we could have done it without that help.
The planning team, and Catherine in particular, were also very helpful - we had one or two issues with our local Planners but their knowledge of the system and how to speak to the planners was very helpful indeed.
Louice also has been with us for most of the project, supporting and coordinating and keeping us informed which has been very helpful.
You can probably guess that we would have no problem in recommending RESI.

RESI have taken a lot of time and trouble to create a customer journey that removes the stress and offers really good advice at key points in the process. Everyone in the team are super helpful and have great experience. Our designer listened to our requirements and made amendments to maximise the use of our space. Jack Brigden who was helping us when we got to building control and builder quote stage was very helpful and gave great advice. Its not a cheap process to extend your house these days but I would recommend this team 100%

We have been so grateful to everyone at Resi. Our build was not meant to be a complicated one but their advice with regards to planning applications, building regulations and professional recommendations has been invaluable!

They are very friendly and very professional. Everything is in one place for house extension projects. I cannot recommend them more. Don't waste time and money with cowboys and do it properly.
Update: After initial calls and lots of time spending, in the middle of the project they decided that our project is high risk. So they recommended smallest concept which was nowhere near what we wanted. Also they were asking extra money and new quotation if application is refused... Highly disappointed and very unprofessional. Without trying, how would we know if it's refused or not? But Resi doesn't have enough expertise in our borough, they introduced new rules in midway... Absolutely ridiculous and very poor trading. We were happy at the beginning and they seemed very professional and we trusted them but our trust is broken deeply.. until they declared that our project is high risk, they have already taken £2098.. I would definitely avoid them. Planning to way out and separate our ways with Resi as clearly their business style is not working for us. They are very money orientated, not customer support or advise. More like an information provider. After long emails we couldn't reach any agreement, they didn't understand and still rejecting the idea and still asking for a money... Very poor and unprofessional ethic of business..

I’m currently in the planning stage of my extension project, and the process so far has been clear, professional, and well organised.
Communication has been excellent, and the dashboard makes it easy to track progress and understand next steps. As a first-time homeowner undertaking an extension, I’ve really valued the structured guidance and expert support.
This review reflects my experience at the planning stage only, and I’ll update it as the project progresses.

We had a great experience working with this architect on our home design. The design process was smooth, thoughtful, and well managed from start to finish. What really stood out was their expertise in securing the necessary permissions, especially given how challenging and complex the approval process was. They handled everything professionally and efficiently, which saved us a lot of time and stress. We’re very happy with the result and would highly recommend them to anyone looking for a reliable and knowledgeable architect.
Thank you once again to everyone involved—especially my heartfelt thanks to Ulker Kasif for your exceptional dedication.

We wanted a single storey side extension, but had no idea where to start. I came across Resi and having had an initial sales call with them, then a follow-up call to answer all my questions, we decided to go ahead.
They assigned an Account Manager, Em, who has been fantastic the whole way, regularly keeping in touch via phone and message.
Their designer, Carleton, worked with us to create our project, maximising the space available for the build whilst keeping within local council regulations, and submitted our planning application for us.
Jack organised a number of builders to quote on our project, and at this stage we are yet to go ahead having only just received our approval on our planning application. But the early signs are good, the construction company have already been round, we have been in regular contact and we are excited to proceed with the work.
I thoroughly recommend using Resi for any construction project and I would happily use them again in the future.

Lots of resources. Help you through it step by step. Clarity about the different stages and costs. Saves a lot of time doing research and reading. We are at the stage of having just received planning permission and waiting for building regulation drawings - so not completely done yet but well on our way. The team have been very responsive to messages and questions. The online platform has suited us - you can look at things when you are able. Agus, Em and Jack have all been good to work with. I appreciated Em’s prompts to get me to do things ready for the next stage.

Resi has been incredibly helpful, this is our first time taking on a project like this and they have been great at taking time to answer all my questions, as well as get the designs just right. It really helped that we could go back and forth as many times as needed until we were confident we had got there.
