Restoration & Refurbishment- 11 Dec 2020
Gus and his team are outstanding workmen with top workmanship. I'm delighted with the planning, the work in progress and the parts that have already been completed. All contacts were fair and easy to understand. Work was broken up into bit size amounts so was affordable and easy to work my around, pertaining to work and family arrangements (Xmas period). All material used is off high quality, work areas were always left tidy and secure, works were always carried out safely, quickly and efficiently. I've already planned to do further works through Gus Desighns because a company who do exactly what they say they'll do, and more, is hard to find. It has been a pleasure thus far! This company is the living definition of professionalism.

Zen came round to see job and returned competitive quote quickly. He was able to start a few days later, turned up on time and completed the works with the designated 2 day time frame, working essentially 2 full days (not my experience of builders in UK who are only onsite for 5 hours a day). He cleaned up the site and did a good job. Would use him again.

Latest review:
Architecture- 18 Aug 2025
Despite some initial positives, the project was ultimately marred by poor communication, unprofessional conduct & serious breaches of trust. We strongly advise against using Bluelime due to the stress, financial impact, & unresolved issues we faced. While kitchen & bathroom installations were OK & progressed quickly, Bluelime deviated from approved plans in a conservation area, causing compliance issues (estimated correction costs of £15–£20k). Heating & insulation were poorly installed, & second opinions confirmed our dissatisfaction. Communication broke down, with responses defensive and intimidating. Costs rose unexpectedly (e.g. door fitting from £1200 to £2640) & inflated quotes in later stages. The property wasn’t ready for move-in multiple times, disrupting our young family. Additional concerns included missing tools, ignored warranties, inconsistent workmanship & misleading claims about affiliations. We urge others to check Bluelime (Alton Campbell) on Companies House.

We have been working with Derek Borkiewicz (Sebek Construction) on a renovation of a garden flat in Little Venice since last autumn. We needed to completely restore the whole flat, including the garden. This was our second renovation project and by this time we knew what we wanted to do, which mistakes to avoid and what to pretend from a qualified builder. We will never stop saying how lucky we have been to find Derek and his team! Derek is not only a professional builder who is very careful to the smallest of the details. He is not only a very good project manager who is constantly checking the work of his men. Derek is a friend who takes on board a project like it is his own project. He suggested the most convenient and best solutions for any problem we came across during the works. There wasn’t a time when he didn’t know what to do to solve a difficult situation (and there are lots of small and big issues coming up in a renovation work) no matter how complicate they were and how long it took to solve them. His availability and his courtesy are incredible above all in a fast running city like London. This is priceless to us. His hard work can be seen in the wonderful result we reached with this garden flat. If we ever decide to work on another project we won’t think twice about working with Derek once again. In fact, now that we found the perfect man to work with, we are looking forward to finding another renovation project to work on! Monica

Bathroom Fitting- 2 Jan 2025
Extremely Disappinted with Planetium Construction- I hired Planetium for a 59k renovation job. Initially, the workmanship was acceptable only because I supervised closely and had them redo substandard work multiple times. However, before the job has been complete, I discovered already a roof leak in the master bedroom, direcly under the newly renovated bathroom. Despite my repeated requests, Planetium refused to take responsiblity or fix the issue. Just telling me need additional charges for the work. Worst still, Adrian the owner, demanded I pay the final balance of 1840 before they would address the GF heating which stopped working after they installed the new controller. When I reasonably refused to pay before they complete the job , Adrian swore at me over the phone the most offensive language. Furthermore, they promised to replace a new Miele microwave for the one they damaged during installation but now just walked away. Leaving me unresolved issues and additional repair cost!

Conversions - General- 30 Jun 2017
The project was a complete renovation of 2 bedroom period flat - adjusting internal walls, new kitchen, 2 new bathrooms, electrics, boiler, rads, new floor etc + full decoration. The Home Design & Build team were fantastic from start to finish - I'd give them 5 stars and would fully recommend. The quality of the work is outstanding - great craftsmanship and attention to detail + a very 'can-do' attitude to the bespoke elements and alterations that occurred throughout the project. The quote was clear and competitive, and the project stayed on budget aside from a few small additions to the scope which were added on at fair and transparent rates. It also stayed within the planned timescales (which is a first from my experience) and the team worked hard to complete on time. Both Lalli (who managed the project) and Mario (who led the work) were great to work with, highly capable and full of helpful and practical suggestions to the detail of the design.
