Conversions - General- 5 May 2025
Zak and his cousin began working on our project on the 10th of March and delivered everything on time. From start to finish, they were consistent, meticulous, and completely committed to bringing my vision to life. They worked collaboratively with me throughout the process, always open to ideas and focused on achieving the best outcome. Together, they handled everything — brickwork, building, tiling, rendering, plumbing, and electrical — with a high level of skill and professionalism. The quality of their work speaks for itself, and I’ve already recommended them to others. We are truly grateful for all the hard work they put in and couldn’t be more pleased with the final result.
G.A.S GENERAL BUILDING SERVICES Ltd
Rating: 5 out of 5
Garage Conversion Specialist in Holborn, West London
ONE COMPANY. ONE PROCESS. ONE POINT OF RESPONSIBILITY. Hi, I'm George Sora, Certified Passive House Designer and founder of RetrofitIQ powered by G.A.S General Building Services Ltd. My approach is different from traditional builders because every recommendation and every upgrade is based on proven Passive House Principles and building physics, not guesswork. Whether the problem is condensation, mould, damp, heat loss, air leakage, poor ventilation, uncomfortable rooms or excessive noise, I follow a structured process designed to identify and solve the root cause: INVESTIGATE → DIAGNOSE → DESIGN → REMEDIATE → VERIFY Using professional equipment including thermal imaging cameras, moisture meters, blower door airtightness testing, smoke tracing and ventilation assessments, I can identify hidden defects that are often missed during standard inspections. As a Certified Passive House Designer, I apply the five key Passive House Principles wherever appropriate: • Airtightness • High Performance Insulation • Thermal Bridge Reduction • High Performance Windows & Doors • Controlled Ventilation This allows me to deliver solutions that are not only visually finished to a high standard, but also healthier, more comfortable, more energy efficient and built to perform long term. Services include: • Thermal Imaging Surveys • Blower Door Airtightness Testing • Damp, Moisture & Condensation Investigations • Ventilation & Indoor Air Quality Assessments • Soundproofing & Acoustic Improvements • Internal Wall Insulation • Loft, Floor & Roof Insulation Upgrades • Air Leakage Reduction • Retrofit & Energy Efficiency Improvements • Refurbishment & Building Works From diagnosis through to completion, clients deal with one company and one accountable team. No guesswork. No unnecessary treatments. Measured. Diagnosed. Designed. Remediated. Verified.

Loft Conversion- 31 Mar 2026
We recently hired Altin to do our mansard loft conversion and honestly, it was a really good experience from start to finish. He was always on time, worked really hard, and his whole team put in a lot of effort every day. Communication was easy and straightforward, which made things much less stressful for us. The project was finished on time as agreed, and we’re really happy with the quality of the work. Altin was also super helpful whenever we had questions and helped a lot with building control, which made a big difference. It’s quite a messy job (cutting through the ceiling and putting in a staircase), but they did everything they could to keep things as clean and tidy as possible, which we really appreciated. Overall, we had a great experience and are very happy with how everything turned out. I’d definitely recommend Altin to anyone thinking about a loft conversion.

Restoration & Refurbishment- 31 Aug 2020
It was a pleasure dealing with Peter and his team from start to finish and we couldn’t be happier with the work that they did. I was impressed with Peter’s previous work and we developed a good rapport from the first meeting and I felt that I could trust him with the work. He was clear about the detail of the work that needed doing upfront and his quote was itemised to reflect what each element would cost. The work was done on time and of a high quality and Peter was responsive at all times to any questions or concerns we had. He also made great suggestions of how we could do things better and was open to our ideas and realising our dream. His team were punctual, friendly and took care of the house ensuring the work that they did was of a high standard at all times and attention to detail which really has made a difference now that the project is completed. I wouldn’t hesitate to recommend Future shapes to anyone and would certainly use them again.

Conversions - General- 11 Oct 2022
We've been seriously impressed with Pawel and his team. They opened up our rear dining room/kitchen wall using an RSJ, following our engineer's drawings perfectly. They also did a few bits of plumbing and bricked up one of the windows at the rear, which is where the new kitchen will be fitted. They were incredibly tidy and really pleasant and courteous to be around, which my wife was so grateful for given we live in a busy family house (most builders are not like this...), I can't thank them enough! We will definitely be using them again in the not-so-distant future!

Very impressed by Eugene's work. I hired him to build a bin shed for my front garden. He took the time to understand what I wanted and work out how he could combine the look I was after with a stable structure. I am so pleased with my new shed. Eugene is trustworthy and reliable and I will hire him for other work in the future

Plumbing- 18 Jul 2023
Ross has excited expectations in conducting the job I hired him for. The job consisted in locating and eliminating a bathroom smell, and he contacted the job successfully and at really affordable rates. The communication from the offset was timely, concise and clear. He visited my property once and tackled the issue, offering to come back free of charge in case the issue would persist. After his first intervention the smell nearly went away, but came back after a few days, way less prominently than originally. As promised, Ross came back free of charge and tried another solution, which solved the problem entirely. Throughout, I was impressed by his professionalism and efficiency. Highly recommended!
