How To Choose A Home Extension Builder

24th September 2021

Choosing the right home extension builder is an important decision that will impact your life for many years to come. To make the process of choosing a home extension builder easier, we’ve compiled this list of questions you should ask before hiring one:

  • How long have they been in business?
  • Do they employ their own staff or subcontract work out? What are their qualifications and certifications?
  • Do they offer any warranties with their services (e.g., guarantees)?
  • What kind of warranty does it cover (e.g., materials, labour, etc.)?
  • How much coverage do I get on my warranty (i.e., full replacement cost for 10 years)?
  • If I ever need to make a claim on my insurance

Find Out If They’ve Done Similar Extensions To Yours

As much as each project is unique, prior experience with a particular style can be extremely beneficial. From understanding the best way to maximise efficiency to providing insight into how to maintain a set budget. Don’t be afraid to visit an architect’s previous project and discuss the issues they have encountered and overcame in the past.

Make Sure You Are Comfortable With Them

When you are planning your extension and the right architect for your project, you need to remember that you will be working closely on this project. Both yourself and the architect should take pride in the project, therefore you must ensure that you are comfortable with the architect you choose. Remember you need to be open and honest with your architect when it comes to your expectations and the budget you have set for the project in order for them to be able to work toward the best outcome possible.

Look Out For Experience As Much As Accreditations

Experience can be more important than accreditation in some situations. When you are looking at potential architects be sure to discuss the exact role they performed in their previous projects. For example, if you select an architect to be a contract administrator, and they only have experience in the design phase. Also, use platforms such as MyBuilder or Trusted Trader to check the reputation of the architect you are interested in.

Get Like-For-Like Quotes And Make Sure Everything Is Included

Like in many industries one architect might charge more than another. It is important to understand what the additional fees are for and which stage of the process they will be allocated to. We recommend requesting itemised quotes for the work you have requested to best understand how different quotes compare. Even if you have essentially decided on an architect it may still be worth requesting two additional quotes, if nothing else for the benefits of comparison.

Establish A Payment Plan

At some point in any consultation, the conversation will turn to pay. Whether you plan to pay upfront or arrange a payment plan this needs to be set out and planned early on to ensure you and the architect fully understand the agreement. Many different payment plans can be arranged depending on your needs and the flexibility of your architect. If you have a payment plan in mind, discuss the options with them and come to an agreement that will work for both parties.

Check Their Familiarity With Planning Permission And Local Regulations

Planning permission and your local regulations can be one of the most complex stages of your extension. For this reason, you should discuss with your architect what experience they have with the planning authorities and the regulations of your local council. It can be extremely disappointing to agree on a design for your extension and then discover the plan is declined by your local council.

Agree on What Aftercare Will Happen After The Build

As with any project, complications can manifest at many points in the construction process. We can almost guarantee that at some point you will encounter an unexpected complication. You need to be sure that if you encounter one of these issues you can rely on your architect to help resolve the issue at no additional cost. Or at least at a pre-arranged cost.

When it comes to choosing a home extension builder, there are many factors that you need to consider. From budget and personal taste to the type of building materials used in your house, these considerations will determine how much work needs to be done before construction can begin.

We’ve outlined some important questions for you above so that you can get started on what is often an arduous process. Contact Detailed Planning for more if you need more information about how our team works together to plan projects efficiently and successfully.

We have used Detailed Planning to help design and obtain planning for our single story extension converting our one... bedroom flat to a two bed. We have found them to be extremely helpful, communicating the process and how things work throughout. We were particularly happy with their ability to negotiate our extension depth with the planning office, resulting in 3.5 metres instead of the permitted 3m, which was crucial for our space to work. We look forward to working with them for the rest of the more

Paul & Emily are fantastic, they have done everything from start to finish for our planning permission and technical... drawings and the quality of their work is very high (I guess it is in the name - detailed!)They have been patient with all our design changes, provided lots of advice, walked us through the process of who to engage with, when etc. and were always responsive and helpful when we have questions both via email and phone. This is our first major project and we are doing a loft conversion and remodelling the entire house so to have this support has been invaluable and well worth the money.We actually found them on trust a trader and obtained a few other quotes, DP was the most reasonable price wise, had the right qualifications, good reviews and a big plus was their well evidenced portfolio of work & experience in the area. It was a no brainier and they really have delivered beyond our expectations, most things have also been done via emails and zoom calls so the flexibility was there which really worked for us, would recommend them to anyone!read more

Detailed Planning were recommended to me by a friend. We found their prices very reasonable so instructed them to draw... up plans for our extension.Right from their initial visit and all the way through to the finished plans we could not have asked for better service.Paul and Emily were always very easy to get hold of, which I'm told is not the case for all architects. They answered every query we had and solved every issue that we encountered during the planning and party wall agreements with minimal fuss and in good time. They even sorted our build over agreement for our manhole to be moved.They work extremely well with their recommended engineer, surveyor and building control company to deliver a very good package.Thank you Paul, Emily and everyone at Detailed Planning. We can't wait for our extension to be more
