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.

Joinery & Cabinet Making- 15 Oct 2018
We hired Sam to build us some shelves and storage units in our two alcoves. He was very professional throughout and performed an excellent job whilst keep the house clean and tidy considering the weather conditions. He even assisted with extra design elements that were not part of the original scope. Overall the work was done on time, to the amount quoted and to a high standard. A very friendly and helpful service and always willing to go a step further than required. We would recommend Sam if you require any sort of carpentry assistance around your home.

George has worked on 2 projects with me so far. He's my go too builder and I'd recommend him above anyone else. The project we worked on together included a loft and extension on one project and another loft and extension on another. Both projects were stripped right back and the finished product was brilliant. George is on-site every day and runs the job in a professional manor. Works well with neighbours and keeps the area clean as well. His workmanship is great but his carpentry skills are on another level. He'll make wardrobes fit stairs etc. the finishing on his projects are sensational. A must hire!

I would 100% recommend John and his team. We have been really unlucky with 3 other builders taking off with our money and not completing the work. John is very professional, took on someone else’s mess and done a brilliant job. We wanted exposed oak rafter detail and the team done an excellent job. John is very good at problem solving on the spot when there are issues, he is very approachable and keeps you updated with the progress throughout the job. What he has been good at is also talking through different options with us before doing different sections of the work and he does not take short cuts. If you need excellent honest builders John is your guy! We will get the decorations done and post the end product.

Restoration & Refurbishment- 20 Jul 2015
We hired Zebra Property for a complete strip out and refurbishment of a GF flat. The JOB: The job included initial removal of existing bathroom, kitchen and flooring.

Exquisite Design and Build recently reworked and refurbished our new, six bedroom detached house, having previously completed a kitchen extension at our last property. Andrei’s work is of an incredibly high standard. He shows great attention to detail throughout the entire process. Not only does he execute the work beautifully, but he offers great design ideas and and suggestions. With regard to contracting, pricing and invoicing, Andrei provides clear and accurate documentation which gives us complete trust in his ability to work within our budget. Andrei and his team are an absolute pleasure to work with; hardworking, punctual and tidy. I have recommended them to three other friends, all of whom chose to work with him on their extension/refurbishment projects and were equally delighted with the results. I would not hesitate to recommend Exquisite Design and Build to anyone, regardless of the size and complexity of their project.

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.

Questions to ask local loft conversion companies in Upper Norwood

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 Upper Norwood?

A local loft conversion company in Upper Norwood 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 Upper Norwood 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 Upper Norwood 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 Upper Norwood

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 Upper Norwood before agreeing to start the work.

Do I need planning permission for a loft conversion in Upper Norwood?

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 Upper Norwood 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 Upper Norwood loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
