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

Haxhi and his team exceed my expectations. We did agree on a bathroom renovation which basically everything was done from scratch. He was always on time and he met the deadline of the project. I had an issue with my water pump but he managed to fix it for little cost. Also he did the tiles for me on the wall and floor with very minimum waste and he did a brilliant job. We changed the position of the basin in order to save space and we did replace it the washing machine(hidden). We are now working on my other property to renovate the bathroom. Hahxi is very professional, knows the job very well, he did coordinate with me on every step to make sure we are on the same page . I strongly recommend him for any renovation project you may have.

Latest review:
I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

You NEED Housi on your project, they took the stress out of our renovation!! We would highly recommend! We got in touch with Housi to help with ideas to renovate a new property I was buying. Holly from Housi helped us with architectural and industry advise throughout the process even before starting full design services which helped me understand my budget more and where items from the survey and my design ideas could overlap. As I was trying to limit costs, Housi helped develop a phased approach to the works as well as assessing options to have a self contained rental unit to bring in income to pay for the final works later. Overall, Holly helped us find minimal abortive works whilst trying to maximise value and functionality. As well as design strategy, she helped us submit a licence to alter application as we found out the house was under a covenant agreement, and managed the project through tender also - meeting with builders and getting quotes. Most importantly, she was able to advise us where builders may be overcharging so we could assess the right builders for us. Working with Housi really made a difference to our project by helping us understand the different stages of a renovation. Holly offered so much more advice and reassurance than any previous professionals we had worked with on our last house and even helped us source re-claimed steel as we wanted to be as circular as possible.

Norbi is an exceptionally talented carpenter. He was the team lead on our major building project when we restored our Victorian house over an 18 month period. All his work was superior, from replacing ceilings and ceiling roses, to laying the new herringbone floor with electric underfloor heating. He was always polite, well mannered, and respectful. Norbi takes pride in his work and genuinely cares about the finished result in your home, a rare quality amongst many. We cannot recommend him highly enough.

Questions to ask local loft conversion companies in The City

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 The City?

A local loft conversion company in The City 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 The City 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 The City 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 The City

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 The City before agreeing to start the work.

Do I need planning permission for a loft conversion in The City?

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