    House Extension London

    Would you like to improve it before selling it?
    Refurbishing a home before selling it can be a great investment, especially if the work makes a significant difference to the buyer.
    In terms of asking price, larger pieces that add square footage are considered. Small details, though, might make a difference, as buyers prefer ready-to-move-in residences. Repainting, updating the bathrooms and toilets, and fixing the boiler and heating in general are all small details that can make a big difference when it comes to selling your home.

    Refurbishment Services

    Each refurbishing project is unique, and you’ll discover the right match for your needs in Buildify.

    Are you renovating a house or a flat?

    When planning an apartment refurbishment, take into account how the common areas of the building will be affected, the limits and requirements for the use of stairs and maybe lifts, whether a permission to remodel is required, how the building management will be involved, and so on.

    In most cases, a house renovation is easier to plan in terms of access and how it will affect the neighbours. Using public space, sidewalks, and public parking is not always necessary when renovating a home.

    Renovating a House or a Flat in London

    Do you wish to rearrange the furniture, add square footage, extend, or convert the space?
    Extending a property as part of a renovation is usually simple and not as costly as you would assume. Loft conversions and back additions, for example, are frequently included in our renovation projects and can frequently be completed under Permitted Development guidelines. This indicates that the procedure and associated papers are very slim.

    The intricacy of layout changes that affect a building’s current structure can be higher, and expenses will rise proportionately. A basic rear expansion becomes more complicated when a bearing wall is removed to create more living space in the kitchen, for example.

    House Refurbishment before rent out

    Will you live there or will you rent it out?
    When it comes to renovating a home to live in, personal taste and style play a significant role in all decisions. While functionality and return on investment are always crucial, emotional attachment to your own home and how you envision the place of your dreams may be more so.
    For homeowners, the quality and durability of finishes such as the kitchen, windows, boiler, and heating system are critical.

    Homeowners can also use a refurbishment to make major improvements that necessitate structural work and layout changes. A rental property renovation should be designed to appeal to a wider audience, creating a space where potential renters may settle in and make it their own. It’s also crucial to figure out which details matter to potential tenants.

    Typically, the work is done on a smaller scale, the finishes are chosen for their pleasing appearance and reasonable quality, and budget is a consideration.

    Full House Refurbishment London

Increase the square footage with a loft conversion or a rear extension, create a kitchen/living room, add an ensuite, or perhaps a patio with a hot tub are all possibilities. We can assist you with all of this and more, including obtaining planning permission, negotiating party wall agreements, and completing any necessary paperwork.

    Flat Refurbishment London

      Architects charge different amounts of money. When it comes to traditional architecture, the field usually tells you to figure out how much your architect will cost by taking a portion of your total budget.

      The normal fee range for a traditional practise is between 5% and 10%.

      Let’s say you’re making a traditional rear extension in London and the whole thing is going to cost about £75,000, for example. You should set aside between £3750 and £7500 for your architect if you choose a standard practise.

      It’s possible that your builder charges by the hour if they don’t use a percentage model. Most of the time, this can be between £75 and £200 an hour. The number of hours your job needs will depend on how big and hard it is.


      You are not required by law to have an architect with you. That being said, this doesn’t mean you shouldn’t think about getting one. An architect can help you get the most out of any big project, like a new build, major renovation, or extension. They can make sure the project meets all the legal requirements, give you advice on budgets and contractors, and much more.

      Book a FREE consultation here to find out more about the benefits of architects.

      A structural engineer is not the same as an architect. Architects can do a lot of different things, but structural engineers usually only do a few main things, like making your house stand up. Most of the time, you need a structural engineer when you’re doing something that could change the way your house is built. Whether it’s adding on the back, converting the loft with an attic, or even getting rid of the chimney. During the building regulations stage, your structural engineer will usually figure out how much your planned structure will weigh and list important parts like steel beams.

      An engineer, on the other hand, can cover…

      • Plans and designs for buildings
      • Models in 3D
      • Submission for planning
      • Building rules and suggestions from contractors
      • Going to sites

      Find out more about “Do I need an architect or a structural engineer?”

      It only takes minutes to find an architect, but it can take some work to find a BEST architect. No matter which architect you choose, you should always take the time to meet with their team. Then you should look at their previous works to see if the work they’ve done fits your needs. You should also make sure they have worked with your local authority before.

      A lot of homeowners are drawn in by fancy prizes, but if you don’t want (or can afford) conceptual architectural design, you might be better off with an architect who mostly works with regular homeowners.

      You should also always pay close attention to reviews of previous customers.

      An architect doesn’t have to be a registered RIBA architect to build a home, and being registered doesn’t always mean they’ll get the best results.

      Yes, Buildify is lucky to have RIBA architects. But we also have a lot of other architects from different backgrounds who have a history of building great homes for everyday individuals. We are a great service because we have helped over 3000 homes across the country since 2011. This is what makes us great, not a certificate.
