House renovations in London

A house renovation is a great investment for your London home. Renovating your property creates the feeling of living in a new home on a far lower budget, and without all the known hassle associated with moving.  



House renovations have a big impact on quality of life and value of the properties. Coming on site is a necessary step to fully understand all the aspects of the process.

  • Meeting in person: a house renovation is all about your desires and what you want to achieve. A face to face session is the only way to understand your priorities, your requirements, your concerns.
  • Viewing the property: do you live in a Victorian mansion block? a detached house? on a street where parking is not allowed? where is the gas meter, the electrical consumer unit? all these and more details are important things to assess for a house renovation project. Even when technical drawings are already provided, a site visit is the way to learn more about the property.

Types of house renovations


    A kitchen renovation can include many alterations, besides installing a new kitchen. You might want to remove an internal wall to make a larger kitchen, for example. Installing new appliances or changing their arrangement will require wiring and plumbing work. New lighting may also be part of the requirements.. If you are extending your house to make a larger kitchen, kitchen renovation might be part of your house extension.


    For a bathroom renovation you may want to change the arrangements of all the fittings and install new sanitaryware. This will mean new plumbing alterations will be required. Tiling and lighting are almost always renovated when refurbishing a bathroom, with specialist workers involved. Often new bathrooms are created during house renovations, adding an ensuite bathroom to the master bedroom or enlarging a ground floor toilet.


    A full house renovation can include kitchen and bathrooms refurbishment, new flooring, heating, wiring and plumbing and a new boiler. It often includes new windows and doors and plastering and painting of the internal and external walls. New ceilings might be included as well.


    A house renovations can be planned as part of an extension project. If you want to extend your property with a basement or loft conversion, a rear or side extension, or all of them, you will want to include a house renovation.. When you perform major alterations, the areas of your house that are not renovated can look unfavourable in contrast with the newly built parts. Plus, a renovation is convenient in terms of time and cost, if a construction company is already working on an extension or a conversion at your property. Check our service pages on basement conversion, loft conversion and house extension for more information.


  • Structural design: if you are changing the layout of your home, structural design can be necessary. If you want to remove a load bearing wall or create roof lights, structural works are required.
  • Interior and architectural design: for your house refurbishment you want to use all the space efficiently. The shape of the rooms is important. The position of each room towards incoming sunlight must also be considered. Having enough storage space and a utility room, for example, are important aspects when planning a house renovation.
  • Finishes and materials: beyond structural and layout alterations, it’s all about finishes when refurbishing a house. Tiles and sanitaryware for the bathroom make a difference to make a stunning new space. The choice of materials, appliances, tiles and worktop for the kitchen is paramount in making a new space that’s both enjoyable and practical.


houseUP also takes on house renovations, when you have all the designs ready, made by your own architect and interior designer. For the work execution, we always appoint the right team for each phase of the project.

Questions and answers

Collected questions that we often hear from you

  • How much will my refurbishment cost? 

    Every good building company will tell you that it is not possible to estimate the cost of refurbishment for a flat or a house before all the details have been defined. But we understand that it is important to have a reference figure before embarking in the process for budgeting purposes.

    We suggest a conservative estimate of £1,750 per square metre as the absolute minimum, and an average of between £2,000 and £3,500 per square metre.

    However, it’s important to keep in mind that there are details that can impact the cost significantly, the most costly being basement excavations or extensions of existing lower ground spaces; inclusion of very large or high spec glazing; very high energy performance materials.

    Additionally, some finishes can increase costs significantly, like paint, tiles or flooring, especially if the surfaces are very large,.

    In general, kitchens can be installed from as low as a few thousand pounds to hundreds of thousands, too.

  • How long will my refurbishment take? 

    As per the duration of a project, it cannot be estimated without the full details. If you want to plan ahead, for alternative accommodation for example, we recommend at least:

    For smaller flat refurbishment, approximately 4 to 6 months. For house refurbishment, approximately 6 – 8 months These estimations relate to straightforward refurbishments like loft conversions or rear and side extensions. More complex work like basement excavations can only be estimated with more details, especially if access to the property is a consideration. Composition of the soil etc are also important factors.

  • Can I live at the property during the refurbishment? 

    We always recommend that you arrange for alternative accommodation during the project.

    Some of our clients choose to live at the property during the work, and, of course, we make that possible. However, please be advised that this arrangement comes with a significant increases in stress, cost and duration of the project.

  • I want to do everything with one company, can you do design and refurbishment for me? 

    Yes we can. We partner with the best London architects to create designs that suit you and your needs. We will match you with architects who have specific experience in your area, share your vision and style for your refurbishment project.

    Doing the design and build with us gives you a view and control of the projected costs of your refurbishment from the very first day. You will be able to make well-informed choices for your design while understanding the cost implications and opting for the best solution for your investment.

    Check out our Design & Build page for more information.

  • I have all the drawings ready with my architect, can you do the building works for me? 

    We certainly can! We work with the best architects in London through a tender process, for clients that choose to have the designs for their refurbishment made by an independent architect.

    We can provide quotes in our own very detailed format or in your architect’s preferred format.

  • Do I need planning permission for my refurbishment? 

    You won’t need planning permission for most refurbishment projects. If you are not changing the external appearance of your flat or your house, you won’t need planning permission. In many cases, you can make a loft conversion or a rear/side extension within permitted development rights. You can find all the details on which type of extensions are allowed under permitted development here.

    However, if you are planning to refurbish a listed building, you may need permission.

  • What works make the biggest difference in the final cost of my refurbishment project? 

    Typically excavation to extend or create a basement under an existing property is one of the most expensive types of work in construction. The cost of finishes is another big factor in the final cost of a flat or house refurbishment.

  • I am buying a property, can you help me estimate how much the refurbishment would cost? 

    When you buy a new property, it is very likely that you’ll plan for a refurbishment. You can find some very good deals on the market, where you can buy a property for a good price when it needs some work done.

    By offering an estimation on work to be done, we can help you make the right decision and offer the right price for the potential property.
