Testimonials (5 testimonials)

House extension


Perfect management of all workers. We are very pleased with the result, everything was done to the plan and as expected. I am already planning to hire them for another project.

House remodelling


From start to finish, we were impressed by Hansen&Co’s building work and management of the project. They made what can be a stressful experience relatively straightforward. When we experienced some challenges or glitches, they kept us informed but dealt with everything themselves, just reaching out when they needed our input. The team were always polite and smiling, and always willing to answer any questions about what was going on. They were all very professional, knowledgeable and courteous. Definitely recommended, especially if you don’t want any hassle but still want things done high-quality.

Whole house renovation


We used them for the whole house renovation. The result is incredible, we didn't expect to see our house to become such a great piece of art. There is now more space and light; each detail is elaborated and have its role. So the design is perfect, we are very happy. As for work process, project manager comunicated to us every week reporting all the work that was done and all the issues come up. They used only high quality materials and all work was done to high quality too. I am recommending this company to all my friends, they are really worth every penny. Although quite dear, I thoguht their price was very reasonable in the balance of service and quality you get

Bathroom and kitchen renovation


Hansen&Co made a bathroom and kitchen re-design for us. The project was very well managed. Builders left no mess after works, they were quite comunicative and informed us every day about what was done when asked. Of course, we are especially happy with the design. We looked for someone who can help us to make the bathroom and kitchen more sleek, but at the same time to keep them fit in style to other house parts. We would like to recommend Hansen&Co as a reliable and professional company.

Loft conversion in a flat


We used Hansen&Co for a loft conversion in a second-floor flat. It took around two months, and the team leader were very responsive and always available. They were a little late once due to a glitch, but they came in over the weekend to make up for the delay. They were also very thoughtful – they separated our living areas so we were not inconvenienced during the works. I would definitely recommend their services! I will surely contact them again in the future and recommend their services to my friends and family.

Case Studies


Listed builidng renovation and Rear glass extension


This is another excellent example of what a top notch design and renovation firm can do with a listed building in a very exclusive neighbourhood. This is a fairly large sized, detached home right on Holland Park that already benefited from a larger garden than most homes of its age in the Borough of Kensington. Knowing of our reputation for high quality design and restoration work, and especially our sensitivity towards the needs of listed buildings, LUX Construction was the natural choice for this project. 

Unlike many of our past projects, the main goal of this renovation was not to add more living space. Rather, our remit was to thoroughly modernise the interior space and garden, without compromising the stately elegance of the home in any way. As with many listed buildings, there were strict restrictions on what could be changed, and the frontage appearance had to be maintained exactly.

Our designers had a fairly free hand with the internal spaces, though. Several more public areas, such as the main stairs, hallway and the formal reception room were changed only minimally, to preserve the elegance and formality of their function in entertaining. Other areas such as the kitchens and bathrooms were given a complete makeover, providing a modern and comfortable, yet still elegant living space. 

The owners did want a rear extension into the garden, and we were able to offer them several options that drew on the existing beauty of the house and garden, with a modern feel. The design chosen included an extension with a full, 2-storey glass wall facing a modern, minimalist garden area that blends in perfectly with the classic lines of the house itself. 

It is always more difficult to renovate and expand a listed building. That is why it is vital to shop around a bit before settling on a design and build team. LUX Construction has built its reputation for providing the best quality work in Central London with decades of experience and a policy of only hiring the best designers and builders. You can see the results for yourself. This home is now stunning inside, and more than a match for its proud exterior.

Basement extension and Full renovation


Lansdowne road is a lovely, heavily landscaped and green spot near Holland Park. LUX Construction was approached about this Lansdowne Road property because few other renovation and construction firms combine the expertise necessary to work on listed buildings, the all-around design and build capacity and the design sensitivity needed to make this project really shine. 

This home suffered from many of the problems that always seem to beset listed buildings. Whilst very impressive from the front, its internal spaces were dark and uninteresting, and the floor levels varied by as much as six inches. The property did benefit from a rear garden, but the green space was difficult to access or even see from most parts of the house. 

We were able to secure planning permission for a basement extension and a large conservatory on the ground floor. We fitted the conservatory space out as a television and sitting room, just off the main dining area. 

The kitchen was extensively refit, and now features a central island with a hob. This feature alone more than doubled the effective counter space. The home’s two bathrooms got a new look as well. One now features separate bath and shower facilities and walls and floor of luxurious black-veined marble tile. The other features elegant grey marble and a slate shower, which complements the avant-garde all glass basins beautifully.

The new deck placed atop the conservatory lets the owners make better use of something quite rare in the city – open space that isn’t overlooked from all angles. 

The full internal refit also gave us the opportunity to address some problems that had bothered the owners for years. All of the internal floors were replaced and levelled, removing several internal step-ups. Two upstairs rooms were combined to give a new master bedroom incorporating a bay window, which the owners tell us is now their favourite room in the house.

Rear extension and Full renovation


This lovely home in south-west London with a small garden was in need of a complete renovation, and LUX Construction was selected for the task. LUX Construction is one of the most experienced and well-established boutique builders in London, offering home and building refurbishment to private clients.

LUX Construction specialises in end-to-end design and building, and was able to do wonders with this project. This property already boasted a small garden/patio area in the back, but this had been very underutilised and poorly presented. In order to make the most of the limited green space, a tiered lawn/patio was selected. Natural wooden walls and a tasteful, modern lighting system combine to enclose the space in a pleasing way. 

A glass-roofed sunroom opens onto the new garden space, taking advantage of the natural sunlight and allowing the space to be enjoyed all year round. Similarly, expansion into the loft yielded more living space, including bedroom, en-suite and office nook. More skylights here help to brighten the room substantially, and provide the illusion of even greater space.

Complete home refurbishments are becoming very common in and around central London, as they are one of the few ways to make spacious family living possible within the city. Many of London’s existing properties have an outmoded and incontinent layout, and do not live up to their full potential in terms of usable space. In this case, the scope of a full refurbishment allowed LUX Construction to redefine the internal and external spaces entirely, creating a spacious, modern home without altering the external façade at all. 

Refurbishment on this scale requires the highest levels of craftsmanship and sensitive design, two qualities that make LUX Construction very sought-after. Once combined with digitally-controlled climate systems, underfloor heating and integral lighting and sound systems, this once cramped structure becomes a modern and comfortable living space even for a large family – a rare thing considering its location.
