We hired this builder for a 2-metre rear extension and a very large garage extension and we’re really happy with the result. The project needed a pile foundation which is a bit more complicated, but they handled everything very professionally. They listened to what we wanted and kept us informed at every stage, which really helped as we were living in the house while the work was being done. The team were friendly, easy to deal with and worked to a good standard. Overall a very good experience and we would happily recommend them.

Samouil and his team at KnowHow Decorating completed a major project restoring our house. Work scope included sorting the tired and broken windows , guttering , fascia panels. Replacing rotten window ledges was done with superbly crafted new hard wood. No task was too difficult as the house was looking shabby. Full painting inside and outside was really well done. We feel like we have a "new" house and Samouil and team are a pleasure to deal with. They go beyond to satisfy you . I do not hesitate to recommend them strongly and will use again anytime .

Restoration & Refurbishment- 9 Sep 2021
The original job for a bathroom renovation turned into a much bigger job. Raphael and his team ended up helping design and renovate the bathroom, bedroom, living room and hallway. The team helped us source all the materials including underfloor heating and an incredibly intricate mosaic tiled floor in the hallway. They provided practical advise about what was best for the space, what would work within our budget and what would be easy to live with. For example, the team installed underfloor heating in the living room using wood effect herringbone ceramic tiles which would help get the maximum efficiency out of the underfloor heating whilst giving us the wooden flooring look we desired. Raphael and the team were excellent throughout delivering high quality work and we were more than happy with the final results. I would highly recommend Raph and his team.

Extensions- 8 Sep 2016
We hired Stone cbm to build our rear extension in Feb 2016 and the job finished on time in April. If there were a best builder award, the winner would be Jas. He is not your typical builder; his communication and execution skills are second to none. He listened to all our requirements like a friend and provide solutions like a pro. We are pleased with the finish. The project is just about on budget and on time, and could have been finished earlier if not for the other tradsman we called in to do other work causing delays. We had all sorts of problems with all the other tradesman and Jas was always there to give us a helping hand. In hindsight, we should have hired jas to do our other work as well as the extension to reduce all the stress. Project managing is much tougher then we thought especially when most of the tradesman out there simply do not care about their reputation at all (even the ones with many good reviews on mybuilder). Jas on the other hand is extremely organized and highly reliable. We would recommend Jas and his team wholeheartedly to anyone and looking forward to working with him again for our next project.

Windows & Doors (uPVC & Metal)- 25 Apr 2026
We found Marian from CM Fixing after the suppliers recommended fitter proved unresponsive and we are so pleased we did. We have found dealing with Marian an absolute pleasure - really responsive communication, excellent price and he has done a fantastic job for us today. They arrived promptly at 8am and fitted our new doors with no fuss and lots of care and it’s all looking amazing. I would recommend Marian and his team to anyone considering an installation.

Loft Conversion- 20 Apr 2018
Hi, Gary came and quoted for boarding my loft, moving the hatch and fitting a loft ladder. I was very happy with the job that Gary did. His guys spent several days over the space of a couple of weeks boarding the loft. They even cut out the boards around the central heating pipes to maximum the space I could use. Gary also spotted a leak in a pipe and took measures to stop it causing harm. The job did take a little longer than I originally thought but they finished everything off in the end. I wouldn't hesitate to recommend Gary.

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

Questions to ask local loft conversion companies in Kings Cross

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 Kings Cross?

A local loft conversion company in Kings Cross 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 Kings Cross 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 Kings Cross 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 Kings Cross

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 Kings Cross before agreeing to start the work.

Do I need planning permission for a loft conversion in Kings Cross?

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