Project: Reveal House | South Woodford | Residential | Clients feedback;

'We hired Colin to design our house remodelling + adding ~100m2. We are VERY HAPPY with his services and STRONGLY RECOMMEND HIM. He just goes the extra mile that others may not do, while charging a very reasonable fixed fee (not % of contract).

Just putting it upfront - we have really quite pushed it with the design (people gasp when I show them plans and 3D pics) and still - PLANNING WAS A BREEZE (what's all the fuss about? ;)) This is thanks to Colin's knowledge of the rules, his advice and taking the time to go to a pre-app meeting at the council. He also checked the revised plans with the planners ahead of submission, which really helped a lot later on.

Colin is also really pleasant to deal with, has lots of knowledge and helped us make informed decisions by avoiding making costly changes.

In the very initial stages he provided us with multiple, creative options for the layout that took our proposals to the next level. There were many things we really liked in all of them and a wow factor in each one too. The final choice really came down to how we wanted to use the space and there were lots of things in there that we would have never thought about. There was simply no comparison between Colin and another company we tried using beforehand, which just made us appreciate him that much more.

Thanks to Colin, we gained at least 10m2 of space, while the layout and all the details have all been really well thought out, with little space lost to circulation.'

Project: Adaptable House | Wimbledon | Residential | Clients feedback;

'Colin (MIDS) worked with us on three different projects for the house and we are very happy with all his work. On the main rear extension/loft conversion, work completed recently, he closely participated in the whole life of the project - from understanding what we needed, drawing up the planning documentation, communicating with the council, working out the tender package, meeting and guiding builders, to surveying the site biweekly to make sure the work was built in accordance with the design. He holds a very high standard for his work and we highly recommend his services.’ 

Project: Up & Over House | Arnos Grove | Residential | Clients feedback;

'We spoke with a number of architects for our project & having completed the project, I can say we are very happy with our choice of Colin & Niamh (MIDS) & would certainly recommend them.

Particularly in terms of the design stage of things, we found their input invaluable. They came up with a design for both our loft & extension which included things we just never would have thought of on our own. They gave us different options for both parts of the build & were happy to let us steer them based on our preferences.

After the design stage, during submissions for planning approval & subsequently throughout the build, they were always on hand to keep us posted & reply promptly to any queries we had. Compared to most of the other ‘professionals’ we encountered throughout the process, we found that they lived up to this moniker: they were professional & efficient from start to finish.'

Project: Brass Home | Walthamstow | Residential | Clients feedback;

'Helpful, friendly and knowledgeable. Colin came up with 3 different designs for turning my (tiny) kitchen and dining room into one, despite there not being much room for manoeuvre. His recommendations and the rationale for them were very helpful, but he was also happy to work with my preferences.

He clearly explained the process, helped find builders to shortlist, helped with the process and had a clear timetable to inspect and sign off works. He was also very quick to get back to me to help with any issues as the project progressed. And total transparency about costs from the start; what MIDS quoted was exactly what I paid, despite the amount of hand-holding they did.

I’d recommend Colin wholeheartedly.'

Project: Clarence House | St Albans | Residential | Clients feedback;


'Thank you so much again for your (MIDS) amazing contribution to this project. Everyone who have seen the old house before are amazed by the transformation. One of our neighbour has already asked for your contact information to recommend you to her friend. It has been a great pleasure working with you!

Project: Rustic Home | Arnos Grove | Residential | Clients feedback;

'We recently used the services of Colin [MIDS] following a recommendation. What a relief we found them! From start to finish, the services provided were very professional, and concise, explained in clear step by step stages to make the whole process extremely streamlined. From explaining what we wanted in the initial meeting, the plans were devised with everything incorporated that we were after. Colin was also happy to tweak as requested until we were happy with the final design. In the early stages of the building work, Colin liaised with our builders as required which was very beneficial to us to avoid any delay with questions along the way.

We would highly recommend the services of Mulhern Iremonger Design Studios and would be contacting Colin again should we wish to do any further future projects! They provides fantastic designs, are excellent value for money, extremely efficient with very high attention to detail, and friendly to work with for your project.'
