We highly recommend Smart House Extension. Professional service and Nesh listened to our brief and delivered exactly what we were looking for on our double extension, plus a few extras! Planning permission went through first time and Nesh always put us at ease and has made the whole process much easier.

Brilliant service from start to finish. Nesh was always in contact via WhatsApp which was really convenient for me. We had our initial discussions and then had a lovely surveyor come to take the details. Not long after I was sent the drawings as well as the most amazing 3d images.
Throughout the whole process of council planning application I was kept informed and what felt like such a daunting process ended up being so simple and straightforward thanks to smart house extension! Would truly recommend. Thanks for all your help and recommendations along the way.

I highly recommend Smart House Extension. I had quite vague ideas for a side and rear extension, but Nesh used his skills and experience to turn this into amazing plans. He really listened to my requirements and what would suit our family. I was delighted when the planning permission came through this week. Nesh was always professional. He would get back to me quickly if I had any questions and answer them fully. I have found the service so efficient and reliable and am now looking forward to the construction phase.

We have been working with Smart House Extension for about a year on several numbers of projects. As a Structural Engineers, we pay attention to how Architect prepare his drawings, how good communication is and what is his work ethos. All these made impression on us and we can definitely recommend this firm to work with. They are accurate, always prompt in answers (to Client and Engineers) and helpful.

We have been delighted with the service provided by Swati & her team at Smart House Extensions. Our project was a Kitchen redesign and we did wonder if a smaller project would command a good service from busy architects. In practice, we have received excellent service in terms of design and project management. We worked most closely with all team members & they all made important contributions. Daf was great to work with. The practice provided a great design which Swati finessed as the work progressed. She worked hard to identify great fittings and was an excellent project manager. SmartHouse linked us up with a builder who turned out to be very professional with a great work ethic. All in all an excellent service and we would highly recommend Swati & her team at Smart House Extensions.

I first started dealing with Nesh and thereafter Swati way back in early 2018.
Their designs for other clients originally caught our eye and after speaking to them, they emerged top of our shortlist.
Subsequently, I've gone through a few iterations of differing designs with them, always been dealt with in a prompt professional way culminating in them drawing up and pushing the scheme through planning which was by no means a given.
Over several meetings, nothing was too much trouble and their positivity in seeking out solutions to any potential problems or concerns on our behalf was very reassuring.
I would definitely recommend.

I was aware of this project before Sunder Architects took it on and they have done a stunning job in maximising the potential for the site as there were limitations on the area that could be used for building. The finished house reflects the clients' aspirations perfectly and is a great example of finessed contemporary design that creates a home, not just a house.

The drawings and visualisations were fantastic and we were granted planning permission with no worries despite the size (two storey on the side and single storey rear) of extensioI think the 3D images really helped both us and the planners, so highly recommended!

Nesh provided a brief consultation on the available options we were considering, pointing us in the direction of the ideas he thought were best to pursue. We covered single and two-storey side and rear extensions, garden rooms, and loft conversions. Nesh referenced ideas from other projects he'd worked on, and suggested companies to contact for further consultation on aspects of the build. When we're ready to proceed, I'm very much looking forward to working with Nesh.

We hired Smarthouseextension to help us through the process of building a single-storey rear extension to our property in Penarth. They listened to what we were looking to achieve and brought the right combination of flair, imagination and pragmatism. Their communication skills were excellent throughout and hurdles were overcome relatively simply. They found us an excellent team of builders which took another weight off. We would have no hesitation in recommending Smarthouseextension and in fact have already done so to a number of our friends.

Swati & her team have an extremely wide range of project knowledge covering many different aspects and specialisms. They are gifted at combining architectural and interior design elements together in a way that gives a very cohesive language to a project.
The team is very well connected with many professionals, and is a highly organised architect/project manager, able to deal with a huge amount of detail without losing sight of the ‘big picture’.
Swati is also a very pleasant, calm and principled person to work with, we would strongly recommend him to anyone for projects large and small.

I chose Smart House Extension after a friend describing their experience which was also very positive. I have been looking to create a better work space for me as an artist and i was struggling to get someone to appreciate what the space needed to offer. Smart House Extension were really visionary and extremely helpful at describing the options and working within my budget. The follow up work has been consistently good and any questions i have needed answered were followed up immediately. Having work done can be quite stressful but this has been my best experience yet. I will definitely be recommending this company to my friends and family and will look forward to working with them again.

When we met with the Smart House Extension team, we'd already discussed our vision with several other architects. They were the only ones that only discussed solutions, rather than compromises. They immediately appealed due to their practical approach, including a wealth of knowledge on the practical aspects of house-building, and how to achieve our goals within budget.
They provided floor plan drawings, elevation drawings, and a 3d drawing that we could play around with and use to walk around the house as it will eventually look.
We've now ended up with an architecture for our house that completely fulfills our requirements and original vision, a recommended builder, and planning was permitted first time by the council with no amendments. Can't ask for more really!

We used Smart House Extension to provide us with professional guidance, take our thoughts and turn them into clear plans which were then submitted to our local authority for planning permission. From the very outset we were hugely impressed by the support we received. Nothing was too much trouble and we always felt that someone was on the end of the phone or email to speak to us whenever we had any thoughts or questions. The plans were clear and fitted exactly with our brief. The actual planning approval process could not have been smoother. We were granted permission ahead of our anticipated schedule and with almost no conditions - we got everything that we had hoped for when we began the project. Smart House Extension were very helpful recommending other professionals to manage different aspects such as a structural engineer and building inspector. We haven't begun the building phase yet but we are well set for that to begin. Many thanks to all the team for your support. I have already recommended and would have no hesitation continuing to do so. Thank you.

Work was a kitchen and garage extension from scratch. All the build regulations were met with the drawings, the costs were broken down in affordable chunks. Got good recommendations for builders and other trades within the building industry. I would definitely use Smart House Extension again.
