If you want a hassle free experience choose these folks. Everything was on time and nobody disappeared to work on other jobs - like I've experienced with other builders. Yes there were a few snags as you'd expect, but they got sorted quickly. The teams doing the actual works are excellent too. They seriously work hard and are skilled craftsmen. The project managers are responsive and genuinely care. It's a solid outfit. Less

We were part of three houses all having side return and kitchen extensions in a row in South London. We had a dormer loft extension in addition for good measure. It was a six month job and turned our lives upside down during lockdown! We looked at a number of companies before opting for Plus Rooms. The clarity of the quotations and the detail they provided up front were more than others and provided more certainty than other builders. They weren't the cheapest but were exceptionally competitive on price given what they offered. The design of the building work was a smooth experience although you will need to push for things you want to be included. Plus Rooms provide all designs but it's useful to have clear ideas about what you want rather than just be led by what Plus Rooms suggest. The build itself was smooth. Almost everything was done to time and cost with little to no remedial action needed a year on to fix anything. The project management Plus Rooms provided was excellent and guided us through the work fairly smoothly and kept us up to date on what was happening and to come. Things went wrong, of course, such as pipes being in slightly the wrong place, but it was dealt with and rectified almost instantly both by the project manager and the relevant sub contractor. All sub contractors were excellent and we've used them for subsequent work since. The finishing team were outstanding and cheaper than quotes from outside Plus Rooms for similar work. The project management structure took the pressure off the build for us and significantly reduced the stress. All sub contractors were good quality and there was minimal concern about hidden extra costs - we had a quote upfront that was kept to. We did extend the spec of the project slightly (larger skylights, high spec materials, etc) but the cost came in almost exactly to what I'd budgeted for before the work began. Plus Rooms are still in touch with us to deal with any snagging issues but the work was excellent quality and we are delighted with the outcome. For the price Plus Rooms are hard to beat. Less

We are so happy with our new space! Strongly recommend Plus Rooms to all.  The initial project proposal were clearly costed and detailed, with a better project management offer than other companies we researched.  Planning permission took longer than expected and the start was pushed back, but this meant we avoided the worst of the winter weather during construction.  The build was an incredible transformation, we had to live in the upper floors of the property throughout as we were in lockdown, but the team on site were friendly and polite.  The project managers were very knowledgeable, responsive to issues that cropped up, and realistic with our expectations.  Coordination with Braverman for the new kitchen, and Integral for new glass sliding doors and skylights was excellent.  The final finish work was delayed over the Summer, but we're so happy that all is now done.

We used Plus Rooms last year for our side return extension which ended up being caught up in lockdown #1. Even with a global pandemic going on Plus Rooms did an amazing job managing the project and we are extremely happy with the results. They have a great team who were excellent through every step. As with any build there were small issues that crept up but these issues were dealt with quickly via our project manager and all snagging taken care of. As other reviews have said, Plus Rooms manage the project and sub contract out the rest (ie the drawing up of plans, the actual build, plumbing, electrics, glazing etc) but this is done via their teams and what was provided was of a very high standard and well managed by PR. Overall I’d highly recommended. Less

We used Plus Rooms for a kitchen extension and loft conversion. We were very happy from the beginning on their professionalism. The work was completed within the timeframe and budget they had estimated, and we are pleased with the quality of the work. We didn't need to worry to contact or coordinate the different teams working, as they managed the whole project. We would definitely recommend them. Less

Plus Rooms designed and built and extension for me (Living Room Kitchen)  and also remodelled another room to create a utility room and boot room and they redid the bathroom. The work was to a very high standard. The team was responsive and professional. The initial estimate was detailed and quite precise and the process ran as predicted in the estimate. Throughout, the project coordinator explained things well and all contractors were hard working and nice to have around. I would recommend and would use them again in the future. Less

We engaged Plus Rooms to complete a side and rear extension on our mid-terrace house. Overall we are really happy with the outcome of the build- the project ran on time, to budget and the quality of the build and the finishing is excellent. We found all of the people associated with the project a pleasure to work with from the project manager through to the build and finishing teams and including the electricians and plumbers they brought on board. All members of the team were courteous, reliable, professional and good at their jobs. Whilst there were a few hiccups along the way (as to be expected on any build) we felt any problems were dealt with quickly and didn't detract from the timeline or overall finish of the project. We would definitely recommend Plus Rooms and would use them again. Less

We used Plus Rooms for our loft conversion last year and we can thoroughly recommend them. The project management from the drawing up of the plans right through to the finishings was first rate. They are obviously very experienced at this kind of work as they easily dealt with any issues that arose, completing the loft conversion on time. The project coordinator always made sure that we were happy before signing off on work and was brilliant at dealing with any snagging issues we encountered, ensuring that they were dealt with in a timely manner. It was a pleasure to deal with all the contractors and our neighbours even commented on how they nice they were! We?re really happy with the finished conversion and all the extra living space it has given us. Less

Plus Rooms carried out a side and rear extension to our Victorian end of terrace, with a reconfiguration on the ground floor to create a downstairs WC. The whole process from start to finish was managed smoothly and professionally and the team delivered the project to the highest standard. I find the company to be well organised and good at communication, and the builders and the trades people they use are reliable, friendly and extremely hard working. We faced numerous minor and not so minor stumbling blocks along the way, but the project coordinator and the foreman always came up with solutions and sorted out the issues with ease and unquenchable positive energy. Towards the end, the pace of response and action slowed down but I understand that Covid had a lot to answer for, and overall, we are overjoyed with our fabulous new kitchen extension. Less

We were delighted with our Plus Rooms project. The brief was a 3m rear kitchen extension to our Victorian terrace, with a reconfiguration of the ground floor to allow for a downstairs WC / utility room. We chose Plus Rooms both because of the excellent feedback and because of their input into the design of the kitchen during the quotation phase of the project (where other firms played back exactly what we'd initially asked for, Plus Rooms provided useful input and suggested changes; we're in no doubt we've ended up with a more special home because of this). The build was delayed by a couple of months due to the pandemic but once restrictions were lifted the teams worked quickly and efficiently and to the agreed timeframe. Inevitably, there were a few hiccups along the way but what we liked about Plus Rooms was the way that these were dealt with utmost priority by our Project Coordinator (who, incidentally, was excellent and kept us informed of everything we needed to know). A number of contingency costs were highlighted during the quotation phase and in the end we did have to do some additional floor and ceiling levelling, but these costs were in line with expectations and the cost of the build was materially the same as we expected it to be. I?d happily recommend Plus Rooms to anybody looking to do a similar project. Less

I worked with Plus Rooms on my house refurbishment. It included a kitchen extension, building a new garden studio, and interior redecoration. Although the project time was longer than I expected, I was generally pleasant about the services Plus Rooms provided. Some highlights: - They proactively think in your shoes. The house I got was a pretty aged one and the layout was very traditional. They have suggested a modern restructure which I'm really satisfied with now. During the project, they also helped me fix some old legacy issues with the house. - Neighbour friendly. One of the big concerns was how the construction work would impact my neighbours, as it's a terraced house. The feedbacks from my neighbours were very positive. Unfortunately, when you work on such a big project, you will have more or less disruptions to your neighbours, but Plus Rooms were handled all of them pretty well. - Responsiveness. You need to have lots of conversations/communications with your builder when working the construction. I'm happy that Plus Rooms was very responsive. Usually my questions were answered in a day or two. They also promptly notify you about any issues they discovered (there are always unexpected things happening), and propose some solutions. - Good suppliers. They use a range of good suppliers to supply the materials, designs, and appliances. As they always work together, you only need to choose what you want and they will take care of the collaboration between themselves. Less

We used Plus Rooms for our ground floor extension and we are very happy with the completed work. They are very professional and provide excellent support for the end to end process. They use excellent tradespeople who not only work to high standards but are friendly and helpful with their advice. The communication was excellent throughout the project, particularly when we were delayed by the first COVID lockdown. One of the reasons we chose Plus Rooms was the recommendation from a friend and we would be happy to recommend them to our friends. Less

We used Plus Rooms to design, plan and manage a side-return extension on our Victorian property in South-East London. From the offset, the team were helpful and trustworthy. They helped us transform a small and narrow space into a spacious and bright family kitchen-diner which has literally changed our lives! It was fantastic to have a Project Co-ordinator to support us throughout and an excellent team of builders/plumbers and electricians. Less

Recently used Plus Rooms to perform a side-return infill in Peckham, and could not be happier with the work performed. They managed the project from idea - through planning (with a pragmatic surveyor who had to deal with stubborn Southwark council) through to the build and hand over. First rate service across the board - from the clear outline of how they operate through to a detailed project schedule (that they completed 2 weeks ahead of time). The various teams involved from builders to plumbers to electricians are all first rate, and Plus Rooms as a firm went above and beyond to deliver us the kitchen of our dreams. Looking back, it was a major piece of work completed during challenging covid times - but the result is we now have a kitchen that went from a narrow, uninspired, dark, dated space to a light, airy, practical, friendly and welcoming space with an absolute "wow" factor.

We initially commissioned Plus Rooms to build a side return extension and loft conversion. Given the quality of service and workmanship, the project soon expanded and became a refurbishment of the entire house. The project kicked off in the week of the first lockdown so we inevitably came across some hurdles, including a 5 weeks pause. However Plus Rooms were proactive; they communicated a clear plan, articulated the impact of the delay (which they quickly made up when back on site) and implemented stringent health and safety mitigations. Plus Rooms are professional, personable, knowledgeable and trustworthy. The build was executed to the highest standards and was project managed with care and professionalism. The Finishing Team are fantastic. All teams were solutions focused and considerate to the neighbours. We are so pleased with the end result and would highly recommend Plus Rooms to anyone. Less
