We hired Ben (of Kovacs Construction) as our contractor for a ground floor extension and an internal reconfiguration, which included the removal of supporting walls. Our flat is a ground floor flat in a large Victorian house in Forest Hill, South East London. 
This project was completed in coordination with a Project Manager (Brolly Design), which helped provide the oversight for the project. 
For such an extensive project, it has been remarkably low stress and completed on time and to the budget agreed at the beginning of the project. 
Ben has been excellent. He was in regular contact throughout the project, providing regular updates and photos via Whatsapp. Ben accommodated any changes that we asked for and were completed without any complaint. Ben allowed us to visit property whenever we liked to check on its progress. 
Ben communicated any delays and actually made up the time on different areas of the project. Unfortunately, there have been some delays with snagging, but some of these delays can be attributed to external suppliers. 
Ben was receptive to issues and queries from neighbours (both in the freehold property and in adjacent properties) ensuring that these were swiftly rectified where possible. 
The finish and workmanship has been top quality and has transformed the way that we live. Ben has a great eye for detail and can really visualise the finished project. 
Overall, we would highly recommend Kovacs Construction for any future project. In fact, we have already recommended them to friends.

We are delighted with the kitchen/dining room extension completed recently. The workmanship is excellent, and communication throughout the project ensured that myself and my husband had confidence that the work was progressing well. We remained in our house while the work was undertaken and the workmen did everything to minimise disruption. They worked efficiently and left the house clean every day and always advised us of progress. We found Kovacs were always ready to respond to our enquiries. They paid attention to details and understood our needs as customers. We are now enjoying our new space - including the beautiful outside patio. I cant thank Kovacs enough.

We had a great experience with Kovacs Construction, we have a 6 month old baby and they were able to keep mess to minimum which is exactly what we needed in these circumstances. We were assigned a project manager who have been very hardworking and professional. They have used specialists for each of the different stages. We think that their work is the best standard. The whole Kovacs office team have been very supportive and helpful. We are using Kovacs Construction for our next project too.

Recommended. Can't say it enough. If you are looking for a very professional team who works clean, delivers on deadlines and does good quality of work, then don't go any further. No hidden charges or extras, they are the right family business. There were no hidden charges or bad surprises in the end and they guarantee after work service within their contract. Kovacs Construction and Ben professional provide high standard and good value to the client. Every week Heni kept me up to date through the project and delivered the work on time. Can't wait to book you guys again for the next project.

Kovacs Construction renovated a ground floor flat for us. Ben is reliable, does what he says he will and goes the extra mile to ensure that things go as smoothly as possible. His team are really hardworking, professional and efficient. I would definitely recommend Kovacs for big and small projects, it was a pleasure to work with them.

I would have no hesitation in recommending Kovacs Construction Ltd. 
They have now carried out two lots of home improvements for me this year. Back in January they fitted a new bathroom for me, laid new flooring throughout, removed an old built-in wardrobe and built a new one, decorated throughout, fitted a new mantelpiece... more recently they rewired, fitted new lights, fitted new double glazing, damp proofed and re-plastered one problematic wall, wall-mounted a couple of TVs for me, built a custom shelving unit for my front room and hung some pictures.
Next job will be to fit a new kitchen!

They are good to work with and are competitively priced.

Ben and his team were exceptional throughout the entire process of our bathroom renovation. Easy to communicate with, and the guys on the job were professional and lovely to deal with throughout. We are impressed with the high quality of work done and the attention to detail. Our bathroom was not a typical design or layout, and Ben gave extremely helpful advice on how to deal with tricky issues. We highly recommend Kovacs Construction and will be using them again for any works in the future.
