The craftsmanship in the kitchen extension is exceptional,the attention to detail, everything has been finished to a high standard. Throughout the project, we were impressed with the professionalism displayed by everyone involved. Your team was punctual, courteous, and always willing to answer questions and address concerns. This made the entire process much smoother and more enjoyable for us. Your regular updates and open communication were greatly appreciated. We always felt informed about the progress of the project and any changes or decisions that needed to be made. This level of transparency gave us great confidence in your handling of the project. The project was well-managed, with work being completed on schedule and within the agreed budget. We were particularly impressed with how you handled unforeseen issues - they were dealt with swiftly and effectively. The final result of the kitchen extension has exceeded our expectations.

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.

Loft Conversion- 25 Apr 2016
Geoff and his team were a pleasure to have around. They completed our loft extension in the promised five weeks. From the outset we felt the work was safe in their hands and the finished project is probably better than we ever imagined. When it came to the finishing touches, doors, handrails, sockets, etc. Geoff made sure we had exactly what we wanted. We also appreciated the respect they showed for the rest of our house and gardens. We have no reservations about recommending their work.

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.

Questions to ask local loft conversion companies in Avery 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 Avery Hill?

A local loft conversion company in Avery 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 Avery 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 Avery 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 Avery 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 Avery Hill before agreeing to start the work.

Do I need planning permission for a loft conversion in Avery 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 Avery 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 Avery Hill loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
