Let’s start from the beginning with the subject of house extensions.

1. Your house extension should look similar to your original home: Use the Brick Visualization Tool for help in select the correct brick to use.

2. Decide where is the correct place for the extension, take a look to this interactive house extension page for all the law about it.

3. Work out your maximum and minimum budget, this article can help you out: Building and Renovation Costs UK.

4. Create the plans for your extension.If you don’t know how to do it look at this article for more information: House Extension – Designing, Drawing and Submiting your own Planning Application.

5. Run the plans past your neighbours, read why in this article: Keeping in With The Neighbours.

6. Apply for planning permission and building regulations approval. Do you feel confused over what everyone means by plans? Take a look at this article: Planning permission for house extension?

7. The next steps are common sense logistics, fine-tuning and anything else which comes up including:

  • Make any required changes to the plans.
  • Appoint contractors or sub-contractors.
  • Agree with neighbours any times during the day you can start and finish the build.
  • Organise your current space to provide easy access for builders and less disruption for yourself (for example, if you have a spare bedroom, consider making it a temporary sitting room away from the mess).


What is planning permission?

Planning Permission, in simple terms, is like asking if you can do a certain piece of building work. It will be granted or refused. Certain types of work are ‘permitted development’. This means that they can be carried out without any planning permission, so long as they comply with the rules and restrictions explained in the laws. Read more

Permitted Development


You can make certain types of minor changes to your home without needing to apply for planning permission. These are called “permitted development rights“. Certain development is granted an automatic planning permission by the Town and Country Planning (General Permitted Development) Order 1995, as amended, i.e. is classed as ‘permitted development’.

Planning application


If your building work does not qualify as permitted development your remaining option is to apply for planning permission. Keep in mind that while a proposal may not meet permitted development criteria that does not mean it cannot be done. An application for planning permission allows the local planning authority to assess your proposal against a range of criteria and decide whether or not to approve it. You will have to pay a fee.

How do I apply for planning permission?

The Planning Portal is the Government’s official planning website. Every local authority in England and Wales accepts planning applications via the Planning Portal.

There are many benefits to creating and submitting applications online. It can be used to complete applications for consents including:

  • planning permission
  • lawful development certificates
  • listed building consent
  • conservation area consent

How do I contact my local planning authority?

What is a party wall?

If you live in a semi-detached or terraced building, you share a wall or walls with your neighbour.  Such walls are known as party walls.  Party walls separate buildings belonging to different owners.

Where a wall separates two different sized buildings, only the part that is used by both properties is considered to be a party wall.  The rest of the wall belongs to the person on whose land it stands.

Your neighbours agreement must be gotten before starting any building works such as house extensions in London, damp proofing works, structural alterations and some internal refurbishment.

In many cases, excavation or constructing foundations for a new building within 3 or 6 metres of neighbouring properties also needs written agreement. Read the full article at walthamforest.gov.uk

Selecting an architect is one of the most important decisions you will make when you have to start a project. You may use this selection methods:

Qualifications-based selection (QBS) (sometimes called “quality-based selection”) is one of the most common methods of selecting the best architect for the project. In particular, institutions, corporations or public agencies (sometimes represented by a committee) use this method. QBS is a system that chooses an architect on the basis of professional qualifications and proven competence. This procedure will provide your project with the best-qualified architect with whom you can develop a professional relationship. Such a relationship is very important for the kind of in-depth discussion which allows the architect and the engineers to deal effectively with issues on your behalf.

To achieve an objective comparison, QBS uses predetermined, value-based criteria that may include such factors as:

  • the architect’s history and ability to perform required services;
  • related experience such as past performance on similar projects;
  • familiarity with local geography and facilities;
  • experience and skills in project management; and
  • design approach/methodology.

You can find al lot of architect to choose from at this links: List of UK Architect and Architects index
