Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

Loft Conversion- 10 Nov 2016
Paul and his team were able to complete the work within the 6-8 week timescale. They were efficient, clean and overall very pleasant to work with. This was our first renovation project so I was really nervous given all the horror stories you hear about builders but Paul was superb to work with. He kept us in the loop throughout the build and if there were any issues he made sure they were dealt with them without troubling us too much. The quality of their work is outstanding and we are so pleased with the turnout. We had a few add ons to the job which Paul accommodated and nothing seem too much for him and his team. He is highly recommended and we will be calling him to come back and do further work on our house.

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- 19 Apr 2026
Didn’t return to finish the job, respond to calls or messages in response to finishing the job. Sadly wouldn’t hire Ovi & Mihai (O&C) again. Friendly & responsive initially. Worked well, on time, eager to please, did a good job - not perfect but adequate, average attention to detail but corrected when asked. We initially had a faux chimney put in, they touted for more work & provided alcove shelving/cabinet ideas which we subsequently hired them for. They worked intermittently (dad around for first half of job then left for Romania) as this was agreed as best for both parties. However they left the job incomplete once paid (were paid on time, each time, with no bargaining). Didn’t respond to texts or calls, leaving cabinet doors unfinished, large chips & cracks unfilled. Laminate was also poorly cut around hearth stone, left chimney cutout unfinished with no cement to the base. Lack of respect and wouldn’t hire again as cannot trust they won’t disappear. Note previous reviews.

Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects.

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

We recently had a loft extension completed along with wooden flooring throughout the house, underfloor heating installation, and a full silicone render — and we couldn’t be happier with the results! The team were an absolute pleasure to work with from start to finish. Their innovative and creative thinking really set them apart — they found smart solutions to challenges and helped us maximise space and style in ways we hadn’t even considered. What impressed us most was their attention to detail and how clean and tidy they kept the site throughout the project. It made a huge difference knowing the work was being done to such a high standard, without the usual mess and disruption. Whether it was a small detail or a big task, nothing was ever too much trouble. No job was too big or small — they approached everything with the same level of care and professionalism. If you’re looking for a reliable, forward-thinking team who take real pride in their work, I couldn’t recommend them more highly!

Questions to ask local loft conversion companies in Streatham Hill

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 Streatham Hill?

A local loft conversion company in Streatham Hill 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 Streatham Hill 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 Streatham Hill 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 Streatham Hill

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 Streatham Hill before agreeing to start the work.

Do I need planning permission for a loft conversion in Streatham Hill?

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