Loft Conversion- 27 Apr 2022
Completely Surpassed Expectations! We had Williams and his team in to do some under eaves storage. We had what we had in mind, which they quoted for, and whilst doing the work, they identified better ways of doing things, implemented them and still stuck to the agreed price. As these guys do this more than me, they are able to use that expereince, educate the client and achieve phenomenal results. Great value for money, now i have a large, light and usable storage space where I had next to none, my only problem is finding the stuff to fill it with. They even installed lighting meaning it works that much better. Get them in for a quote, if for no other reason than just to understand your options. His team are hardworking, friendly and do the work with a great sense of humor, taking pride in what they do. Gracias Williams!

Latest review:
I met Charlie and his team from CM Builders Ltd when they were completing a loft extension and ground floor extension for one of my neighbours. Quotation and budget I was given an estimate subject to drawings as I was on a strict budget that I had to keep to for the build. Charlie was able to help me keep to the budget, both at the final agreed plan and during the build. The project was complex in that whilst it was a loft extension, all of the house was rebuilt. The only thing kept was the external walls and first floor rafters. Whilst the footprint of the first floor was not being changed I wanted to bring it up to current building standards with extra insulation. All of the plumbing and electrics were also replaced including a new boiler. The overall build has come in on budget, save for agreed enhancements that I did not think of at the planning stage and or building regulations such as double ceiling fire plaster boards. There were also items such as the original stairs that I wanted to keep, but Charlie was able to increase the height space in the kitchen making the worktop much more usable for tall people for a larger part of the kitchen. These were suggested to me as potential options as part of the build. Stage payments The stage payments have all been sensible throughout the build and linked to the ongoing work schedule. I have not therefore had any concerns in this regard. Quality of work This was a very complicated build as unlike the ground floor the first and new second floor are “L” shaped. The new 2nd floor included an en-suite and 2 bedrooms. Overall the house has been increased from 2 bedrooms 1 bathroom, to four doubles and 2 bathrooms. The quality of work is excellent and Charlie project manages his team to ensure that they all deliver to a high standard- if it is not done correctlt they do it again, with Charlie spotting any issues. Timeline of build This has generally gone to plan very well. As with any build you have to be realistic as things will happen outside of anyone’s control. When issues have arisen Charlie manages them to a conclusion. Also be realistic if you are having to manage to a tight budget. I had to plan for various stage receipts of cash before I could order the kitchen and bathroom items - make sure you understand how this impacts the build and availability of the work force, recognising that CM Builders have to book kitchen fitters and plumbers. CM Builders are also very helpful in that they have sorted out issues with the brick work of my freestanding garage (nothing to do with the build) and also a neighbour’s wall that could have been dangerous to the public, should it have failed. Conclusion The whole family are very pleased with the outcome and we now have the equivalent of a brand new house that has been built to a very high standard. This has definitely been worth doing both from a valuation perspective and quality of life perspective. I would not hesitate to instruct Charlie and his team again.

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Carpentry- 1 Jul 2025
They knew exactly what to do when I sent them the requirements regarding the replacement of my door. Due to the Grenfell legislation, I was obligated by the maintenance company of my flat to change my front door to an FD30. Tony and his team were very quick to do a site visit, provide a quote and even gave me some options of which door I could choose from. The installation was very quick and the work spoke for itself. I have recommended them to other residents and would definitely recommend to anyone else.

This was a major piece of work. F&G Design and Build created a stunning new storey to the house. The roof was renewed, new windows inserted back and front, plus a shower, toilet, cabinets and basin in adjoining bathroom. Special mention needs to be made of the extension to the stairway. They copied the original design to perfection (much admired by all those who have seen it). They also refurbished my kitchen to a very high and beautiful standard. They were always friendly and approachable and totally reliable. An absolutely brilliant team, and a pleasure to work with. And they finished the job on time!

Loft Conversion- 14 Aug 2022
Thanks to Thomas, we decided not to do a loft conversion now and do a more upscale conversion once we have the budget. We first planned to do a small-scale conversion, but after consulting with Thomas, he suggested several plans, including upscale ones and recommended us doing an upscale one rather than the small-scale one. His recommendation makes sense, and we decided to follow his suggestion. I had a great discussion with him. He is very open, honest and trustworthy.

Questions to ask local loft conversion companies in Parsons Green

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Parsons Green?

A local loft conversion company in Parsons Green will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Parsons Green should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Parsons Green loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Parsons Green

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Parsons Green before agreeing to start the work.

Do I need planning permission for a loft conversion in Parsons Green?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Parsons Green loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Parsons Green loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
