Altering or building your home
Altering or building your home is a lot like building a car. With a car, you begin by picking a model which gives you a base price. You then choose what engine size you want, what colour would suit you best, and what luxuries you’d like to enjoy, such as chair heating, technology display, sunroof and much more!
When it comes to building your project, the process is similar. You decide what rooms and what space you want and then the main structure of your project is priced and built to create these according to the current building regulations. This is essential to creating a warm wind and watertight home.
Your client choice items are unique to you and your price point.
The exciting part is tailoring your space to you, deciding what client choice items such as your style of kitchen, bathrooms, tiling and more! Your client choice items are unique to you and your price point.
For Example, kitchens can range from...
£15,000 - £75,000+
...tiles can vary from
£30 - £150+ /sqm

get startedSquare meter rate guide
Although a square meterage rate can feel great, it doesn’t account for all the client choice items on your project. Therefore, in our experience, whenever a client has been given a guide square meterage rate - even with the best intentions in the world - it’s usually not accurate.
As a guide, we have prepared a list of examples which shows how much a few different-sized extensions could cost you:
Example 1:
This client created an extension to create a modern, open plan kitchen and living area to suit their families style of living plus adding a utility room and workshop.

How does IDH price?
Our in house pricing team will prepare you a description of works, broken down in an easy-to-read format showing the works from beginning to end. It will include a description of each item, where the works are taking place, the quantities, the rate, and the item costs so you can track the costs down to the penny.
Each detail will be priced using our pricing system which has been mastered over years of experience and based on real time labour and material costs. All materials for your project will be secured at the very best market rate possible through our procurement expert.
So, you will not only get a great price, but a fair price, too.
Just like you, when we buy something, we’re keen to make sure that the agreed price is the price we will pay. That’s why we go into so much detail in our pricing. We want to ensure that every item that can be accounted for is priced for.
What if I only have planning permission drawings?
In order to give you a fixed price quote, we need the details in the building warrant drawings. These details are not in the planning drawings.
But you still deserve to know a guide price! That’s why we provide you with a guide estimate and description of works. Here, we do need to make some educated assumptions based on our years of experience building similar types of projects until the building warrant drawings are provided.
Once we have your building warrant, we can firm that up into a fixed price quote.
We are very confident in our guide estimate pricing as in our experience, very rarely does one of our fixed price quotes fluctuate largely from our guide estimates, unless there is an extremely unique detail or expensive / detail material specified by the architect or engineer.
