Loft Conversions
The loft conversion is an excellent idea for creating additional space. We increasingly adapt unused spaces for creating bathrooms, bedrooms, children’s rooms and even entire apartments. Regardless of whether you want to adapt the loft in a small house or use the attic space in the large building, the possibilities are vast.

What Our customers say

Ground floor refurbishment including structural works, fitting new kitchen and driveway paving
Pawel and team done a fantastic job and we are extremely pleased with how the entire build was completed from start to finish. Pawel was very upfront and honest and delivered on every promise making the whole process very efficient. The team were very tidy and were always happy to help with any extra work. Open honest and transparent about the work. Pawel found a way to accommodate the work in shorter space of time than expected. Good communication and very reasonable price with brilliant quality work.Definitely will use again in the future and I would not hesitate to recommend him.

Complete Kitchen strip down and Refurbishment
I hired PB for kitchen refurbishment, it involved taking out a number of key structural walls, 5 steel beams, complete strip down of all walls, floors, ceiling. Taking out two windows, opening up for bifold door installation. Lowering the floor for wet underfloor heating install and then installation of new kitchen. Pawal has been a honest person to deal with, there were no gaps in work I.E when people did not turn up for etc. He always had solutions for all the small issues. Finishing was excellent! He spent two weeks going through in detail to finish to high standard. Honest guys are GOLD!

Created 2 rooms from 1 by building an internal wall and undertaking electrical work, plastering etc.
Very impressed by Pawel and his team. High quality workmanship with a minimum of fuss. Pawel made helpful suggestions on how we could improve the design of the layout of the rooms and upgraded the electrical installations at no extra cost. Highly recommended.

Side return extension, kitchen fitting, bathroom fitting, extensive refurbishment
Pawel did excellent work on our house side extension and extensive internal refurbishment - new kitchen and bathrooms, removing chimney breasts, new staircase, built fitted wardrobes and utility, decoration.
London, September 2019

Kitchen fitting, bedroom decorated plus flooring, extractor fan replaced and leak fixed in shower
Pawel provide a competitive quote. He is very hard working and conscientious, and the work was finished to a very high standard. Always polite and friendly, and discussed any problems as we went along. The job took longer than anticipated, and Pawel worked long hours to finish it before Christmas, and instead of rushing the job, came back for a couple of days in the new year to finish the tiling. I am so happy with my new ‘posh’ kitchen, and my daughter with her new bedroom. Definitely recommended.
