The written estimate sets out the scope, price, exclusions and provisional sums. Changes to the work and their cost are agreed before the additional work proceeds.

Reviews

Real reviews from London homeowners who hired KRAMAN Ltd. Use the arrows or swipe to read more, or see all reviews on the reviews page.
I have known Kraman Ltd for about 4 years and Alex, the director, for about 10years. Over this time Alex has always been my first choice for any work that I have needed done in or on my home. In 2000 Alex did some refurbishment work for me that I was very pleased with. Due to the quality of his work I then asked if he would work on another refurbishment project. This was to …
I first met Alex in 2002 and he has worked on a number of my high-end, luxury homes and projects over the past 8 years. I have found him to be trustworthy, professional, resourceful and focused. His integrity and ability to strive for perfection sets him apart from other builders. Alex’s excellent building credentials and expertise is re-enforced by his unique ability to f…
After an extensive search of builders, I found Alex through the FMB website. Alex showed us his projects first hand and we were comforted by what we saw and the perfection in which he delivered his projects.Alex discussed our full house renovation with us, explained in detail the process, the unexpected issues and costs involved and was extremely thorough. One thing set him …
I bought a semi-detached house in 2011, which needed some changes. Alex was my builder and he gave very valid recommendations on which things needed to be done and which were not needed, taking into account my budget and (sometimes unusual) ideas. The main works included loft and ceiling insulation, rebuilding of an extension, bathroom renovation, wall sound proofing and a b…
Alex was great! The way he did the whole project management as a matter of course, no hassle for me at all, and everything as promised in time – I don’t think I could have wished for a better builder and project manager. This was extremely important, as I refurbished by whole flat from top to bottom. In hindsight, I can only more admire his time management – most peopl…
We hired Alex Anokhin (Kraman Ltd) to renovate an apartment we recently bought. We could not be happier with the results. Alex’s attention to detail and craftsmanship are superb. He does all his work with a level of care rarely found in builders. We highly recommend him and will be using him again in the future.
We had a leaking extension roof replaced and the quality of the work was outstanding. We didn’t have to wait very long and also the company didn’t exceed the originally agreed budget. If we needed any work done on the house we would always call Kraman company. They are efficient and very professional.
We contracted Kraman Ltd to divide and convert a bedroom to a shower room and dressing room and also to extensively soundproof an outbuilding. Both jobs were far from straightforward and quite a few extras arose along the way. Alex and his crew carried out all of the work to a very high standard and we are very happy with the result. We wouldn’t hesitate to recommend him.
Alex turned up to review the work on time, was polite and knowledgeable and inspired some confidence as to his competence and ability. Likewise with the work he ultimately did. All top notch and either at or above my expectations. Quite simply a pleasure to do business with and I am holding onto his business card!
We used Kraman Ltd to do a total refit of our kitchen and downstairs loo. We are very happy with all of Alex’s work for us. He and his assistant were extremely reliable, always arrived on time, carried out the work in the timescale agreed and cleaned up afterwards. Alex is very honest and easy to communicate with. We would happily recommend him to others and would use his …

Frequently asked questions
Cost, planning, programme, insurance.
Common questions from London homeowners considering a refurbishment, extension or conversion. For the full guide on any one topic, follow the link in each answer.
How much does a loft conversion cost in London?
Every estimate is individual. The price depends on the type of conversion (rear dormer, L-shape mansard or hip-to-gable), the size of the loft, the structural work and the finish. We give a fixed quote after a free site visit. See the loft conversion guide for the types and what drives the cost.
Do I need planning permission for a house extension in London?
The route depends on the proposed design and the property. Some extensions qualify as permitted development; larger rear extensions may require prior approval. Conservation area restrictions and any listed building consent requirement need separate checks. See our house extension page.
What is a side-return extension?
A side-return extension fills in the narrow alley alongside the original rear addition that almost every London Victorian terrace has. The result is a wide kitchen-dining-living space, typically 25 to 40 square metres, opening onto the garden through full-width sliding doors. Most side-returns add 8 to 14 square metres. See the side-return guide for Victorian terraces.
How long does a basement conversion take in London?
The programme depends on the existing structure, excavation, access, waterproofing design and required approvals. We agree the stages and expected duration for the proposed work. See our basement conversion page for the work involved.
Are you insured?
Ask for our current public liability insurance documents and the cover applicable to your project. KRAMAN is a Federation of Master Builders member, an NICEIC approved contractor for electrical works and Gas Safe registered for gas and boiler works. Workmanship and structural warranty terms must be set out in the contract and any applicable policy.
What areas of London do you cover?
East London (Leytonstone, Leyton, Hackney, Walthamstow, Stratford, Wanstead, South Woodford), South East London (Brockley, Greenwich, Lewisham, Blackheath, Docklands), North London (Camden, Islington, Holloway, Wood Green, Highgate, Winchmore Hill) and Central London (Chelsea, South Kensington, Notting Hill, Holland Park, Battersea). Our office is at 35 Elsham Road E11.
How long does a whole-house refurbishment take?
The programme depends on the rooms involved, structural changes, required approvals and delivery of materials. We agree the stages and expected duration for the specific refurbishment before work begins.
Do you handle planning permission and party wall agreements?
We coordinate planning work with the project designer and party wall matters with a surveyor. Heritage consultants prepare and submit listed building consent applications. The required applications, responsibilities and fees are agreed for the project.
