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. The works itself were for a side return wrap around kitchen extension, basement refit, installation of new kitchen and bathroom, new windows (including velux) and bifold doors, tiling and complete decoration throughout. FEEDBACK: Zebra were a great company to work with on this job. Communication levels were clear. There were inevitable delays to the project but there was always a focus to get back on track and deliver as quickly as possible. The resulting finish is a high standard throughout the property, with any minor snags completed quickly. Thank you!

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Loft Conversion- 6 Mar 2018
Loft conversion. We were delighted with Peter and his team. We were impressed with the hard work shown by all of the builders on site.

Extensions- 30 Sep 2025
Overall, I’m very pleased with the work Marin has carried out for us and I’m currently in the process of instructing him to do more work. Marin built a high spec cedar shed for us with electrics and plumbing, some brickwork and laid composite decking. Marin came across, honest and reliable, which in itself is rare. He was on site most mornings to make sure his tradesmen were on the right tracks. Like with a lot of these things there were some issues along the way and I was highly impressed by Marin’s ‘no quibble’ approach to rectify any problems. I myself have a high attention to detail and am quite indecisive (nightmare client) and Marin was happy to work with me with changes to the project without incurring extra costs.

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.

Loft Conversion- 7 Aug 2023
I highly recommend Sohail Faisal of Samz Construction Services Ltd. We chose Sohail's company to complete our Hip to Gable with Rear Dormer Loft Conversion in Guildford and we are delighted with the work. The job was completed to a high standard, within the expected timescale and on budget. Sohail's communication throughout is excellent, taking time to explain what work will be completed on which days, what is involved and how many people will be attending on which days to complete the work. Sohail also let me know exactly when deliveries of materials were arriving and when the skips would be collected etc. Sohail's team of builders are all very friendly, polite, and respectful and do a great job of cleaning up after themselves at the end of each day. In terms of price and payment schedule, this was fair and efficient. Sohail has a payment schedule that works really well - invoicing for staggered payments at certain points, i.e. on delivery of materials, then when the building inspector signs off the first job etc. this makes you feel at ease with the job and confident that everything is always on track. All around I am really happy with the project and have no doubts about recommending Sohail to family and friends - I have already asked Sohail to quote on my next project.

Bathroom Fitting- 2 Jan 2025
Extremely Disappinted with Planetium Construction- I hired Planetium for a 59k renovation job. Initially, the workmanship was acceptable only because I supervised closely and had them redo substandard work multiple times. However, before the job has been complete, I discovered already a roof leak in the master bedroom, direcly under the newly renovated bathroom. Despite my repeated requests, Planetium refused to take responsiblity or fix the issue. Just telling me need additional charges for the work. Worst still, Adrian the owner, demanded I pay the final balance of 1840 before they would address the GF heating which stopped working after they installed the new controller. When I reasonably refused to pay before they complete the job , Adrian swore at me over the phone the most offensive language. Furthermore, they promised to replace a new Miele microwave for the one they damaged during installation but now just walked away. Leaving me unresolved issues and additional repair cost!

Loft Conversion- 17 Dec 2017
Zafer did a great job of boarding our loft and fitting insulation in the rafters. We are really happy with the result (and my husband is never easily pleased!) He was punctual, worked long hours and did a good job tidying up after. His quote was very reasonable too. He even sorted out our heating problem while waiting for something to dry! Really nice guy as well. One of the best tradesmen we’ve used whilst renovating our home. Wouldn’t hesitate to hire him again.

I recently had a full kitchen installation carried out and I’m really pleased with the results. From start to finish, the work was completed to a high standard and everything was done with great attention to detail. The installer was professional, punctual, and easy to communicate with throughout the project. Any issues or questions I had were dealt with quickly and clearly, which gave me confidence that the job was in good hands. The workmanship is excellent – everything is level, neatly finished, and exactly as discussed. They also kept the workspace tidy each day and made sure everything was cleaned up properly once the job was complete. The kitchen looks fantastic and has completely transformed the space. I would happily recommend them to anyone looking for a reliable and skilled kitchen installer, and I would definitely use them again for future work.

Tommy was a wonderful perfectionist and has done beautiful work in our stairway and hallway which had needed refurbishment for a very long time. It feels brand new.

Restoration & Refurbishment- 25 Sep 2025
We were over the moon with our kitchen once Zihni and his team had finished. We had never used this firm before but we will definitely be using them again for future projects. Zihni is calm, knowledgeable, and went over and beyond in helping us not just complete our kitchen project, but in helping us move into a new home smoothly. We are also really appreciative of the rest of his team, as they were all so serious, professional and perfectionists. Zihni's communication was probably the single reason why the completion of our kitchen was such a success.

Questions to ask local loft conversion companies in Camberwell

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 Camberwell?

A local loft conversion company in Camberwell 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 Camberwell 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 Camberwell 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 Camberwell

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 Camberwell before agreeing to start the work.

Do I need planning permission for a loft conversion in Camberwell?

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