Types of house renovations


    As well as installing an entirely new kitchen, a kitchen renovation can include smaller, simpler alterations, for example removing an internal wall to make a larger kitchen space. Or installing new appliances or changing their configuration, which would require wiring and plumbing work. New lighting may also be a requirement. Finally, if you are extending your house to make a larger kitchen, kitchen renovation might form part of your house extension project.


    Bathroom renovations can mean many different options, for example; changing the layout and installing new sanitaryware; adding an en suite to a master bedroom; enlarging a ground floor toilet. In the majority of bathroom renovations, plumbing, tiling and lighting alterations will be necessary and will involve specialist tradespeople.


    A full house renovation can include kitchen and bathrooms refurbishment, new flooring, heating installation, wiring and plumbing installation or alterations, and a new boiler installation. It might also include new windows and doors, and plastering and painting of the internal and external walls. New ceilings might be required 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 most likely need to include some form of renovation. When major alterations are performed, the areas of your house that have not been recently renovated can appear unfavourable in contrast to the newly built parts. What’s more, while an extension or conversion is ongoing, it can be ideal in terms of time, cost and convenience to take on a renovation project. View our service pages on basement conversions, loft conversions and house extensions for more information.


Structural design might be necessary if you are changing the layout of your home. For example, to remove a load-bearing wall or create roof lights, structural works are required.

Interior and architectural design can demonstrate how to improve the use of the space. This takes into consideration; room shape; the position of the room in relation to sunlight; storage facilities.

Beyond structural and layout alterations,finishes add the final touch of personality. Elegant tiles and stylish sanitaryware for the bathroom make a stunning difference to a new space. The choice of materials, appliances, tiles and worktops for the kitchen are paramount to making a space that’s beautiful, practical and enjoyable.

Average cost

Average cost 

The cost for a house renovation is variable and, depends on what the project potentially includes. Needless to say, fully refurbishing a kitchen will cost more than just repainting one.

To offer a ballpark figure, the average cost of a house renovation starts from £2,000 per sqm including the kitchen, finishes like flooring and tiles, installing new sanitary ware, etc. Bear in mind that depending on the quality of the finishes and the size of the alterations, the cost per sqm can vary substantially.


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.
