  • “We are moving into a house that requires a complete renovation. Resi managed to turn round a complete conceptualised project within 48 hours. This has been invaluable for us in determining how best to take the project forward and we are now in a much more informed position. I would have no hesitation in recommending this excellent and efficient service.”

The 2D and 3D visuals were fantastic and helped us visualise all. Highly recommended and really helped us make a decision”

Frequently Asked Questions

Why would I use Resi?

There are plenty of reasons to use Resi to plan your next building project:

  1. If you want your home extension or conversion plans drawn up
  2. If you need clear guidance to navigate the planning permission/permitted development application process
  3. If you’d like to explore the potential for extending your own property, or a property you are interested in purchasing
  4. If you want to understand the costs associated with extending
  5. If you need reassurance around the value you could add to your home
  6. If you prefer to clearly visualise the end result before you start writing checks
  7. If you are thinking of buying a home and want to know how it could develop as your family grows
  8. If you want to stand out in a crowded housing market by demonstrating the potential of the home you’re selling
  9. If you need something concrete to present to contractors for an initial costing
  10. If you want an affordable, high-quality alternative to traditional architects


What does Resi offer?

Our bespoke packages include 2D plans, 3D renders and a supporting report. This includes advice on relevant planning policies, estimated project costs/timeframe and an overview of who will need to be involved during the rest of the building process.

We can also seek planning permission on your behalf if you need it.

Our packages provide maximum value at three key points in your homeowner journey:

  1. To kick-start an extension or conversion for your own home, now or in the future
  2. To provide plans that illustrate the development scope of your home to potential buyers
  3. To understand the potential of a home that you’re considering purchasing

Our online service is designed for speed, convenience and value, without sacrificing quality. We also offer an on-site measured survey/consultation, if you would prefer face to face interaction. 


Why don't I just use a local architect?

If you’re planning something significant or complicated, like building a completely unique house from scratch, working with an amazing architect can make or break the project.

However, most conversions and extensions are simple hundreds-have-been-done-before type jobs. You don’t need someone to reinvent the wheel in order to get the best possible outcome, and you certainly don’t need to pay huge fees up front, particularly if you’re still deciding whether or not to go ahead with the project.

Sometimes you just need an expert to answer a few essential questions:
  • How can the property be developed?
  • How much will the loft conversion or ground floor extension cost?
  • How much value will it add to my home?
  • How likely am I to be granted planning permission?
  • What will the end result look like?
  • How long will the project take?

Resi can provide you with answers to all of these questions (and many more) in under 72 hours, for a far lower cost than any independent architect. 

You can then make an intelligent, informed decision to proceed with the project, wait, or reject the idea quickly, without too much financial outlay.


What information do I need to provide for you to start work on my extension?

As soon as you sign up up to Resi we will walk you through our easy-to-follow process. 

We’ll ask you for:

  • Your name, contact details and the address of the property in question
  • Basic information about the property
  • Your preferred style, estimated budget and a brief description of what you are looking to achieve
  • Uploads of floor plans, inspiration or existing photos of the property (all optional)

We will always let you know if we require further information before we start drawing.


How is it possible to deliver your service without visiting my home?

Our pricing is particularly competitive as we do not require a site visit as standard.

If you have bought or sold in the last 20 years, your floor plans will probably be available from a variety of public sources. Working with these, and a host of other proprietary resources, we can accurately complete 90% of designs remotely. Sometimes we may ask you to cross check measurements using a tape measure. When this is necessary we will guide you through this exercise. 

All of the case studies that can be viewed on our website have been produced without the need for a site visit. 

For the 10% of homes where a site visit is necessary, we will arrange for a measured survey to be carried out by one of our trusted partners. This usually costs between £350 to £450, which will be included in the quotation we provide to you. 


Can I trust you? Are you qualified?

Although we’re online, we’re not robots, and you’ll be speaking with us directly from the moment you make an enquiry. We also offer an onsite measured survey/consultation service, if this is preferred. 

We’ve got qualifications, expertise and a long track record of happy customers. We currently have three ARB registered Architects working at Resi, along with two architectural technologists, so your project is in safe hands.

Collectively we've completed over 750 residential extensions and renovations across the whole of the UK. You can learn more about our founders here.


Can Resi produce a variety of options for my extension?

Yes!

The majority of our clients want to see the simplest, quickest and most cost effective solution for creating more space in their chosen area of their home. However, we are also able to produce what we refer to as the 'art of the possible'; taking you from simple to grand and everything in between. 

Just mention that you would like us to think boldly about your space when you discuss your extension during your initial consultation.
