Adding An Extension To Your Home

Adding a new kitchen or a lounge extension to your house will give you more room inside and raise the home’s value considerably as much as 25%. However, we think a reasonable-sized extension, which does not leave you with a tiny garden, is an excellent idea; something evenly proportionate concerning the garden and house.

Since we get many inquiries about domestic projects such as Extensions and Lofts, we have made a list of items that will make it easier for you to achieve your dream extension. Nevertheless, if you can’t do this task yourself, we have a pre-construction package, allowing us to prepare it for you for a set fee.

In no particular order, these items are what you need; however, additional documents may be required depending on your project’s location.

 1. Architectural drawings and planning permission – if required.

 2. Engineers structural calculations and specifications for any structural steel and any existing wall alterations to be done.

 3. A pre-construction survey of the existing structure and underground services is critical because, more often than not, changes to the underground drainage are required for Thames Water and BCS to sign off your new shiny extension.

 4. Party wall agreement with your neighbours.

 5. The schedule of work, including any additional work, is to be carried out. 

 6. Restrictions and design conditions are generally reserved for conservation areas or party wall agreements and can affect the build costs. 

 7. Have an allowance of £2000-3000 per meter square for extensions overall, but that can vary on other additional works required with wiring, plumbing etc. It may also evolve whether a new kitchen is needed and other internal renovations, which go hand to hand with extensions.

Now what I just mentioned above are the required documents, and, unfortunately, very few potential clients possess all the items mentioned above. Also, there is the other end of the scale with some drawings bought online; therefore, we recommend hiring a local architect.

Consider paying for your quote because, more likely than not, you will get an appropriately detailed quote for your extension. A lot of builders offer free estimates but remember that’s all it is an estimate.

Estimates have a funny way of getting blown out of the water once the building work starts. That is because not one build is the same as every house has a different structure, but that topic we’ll cover in another blog.

Now you are ready to start looking for the right builder because not everyone is suitable to be your builder. Some companies are too big for your job, others are too small, while a few do not have the skill set to complete your extension and may abandon the project halfway.

Therefore, I would recommend using contract with your builder and FMB to have some easy-to-understand contracts fair on both parties. Consider no more than three builders for the job, this action will help you get a clear picture of the cost.

Make sure the quote is specific to your project based as per the architect’s design and structural calculations. That way, you are reasonably confident with your budgeting and can avoid unexpected bills later on, although it must be said that sometimes can not be avoided.

Once you have a clear plan and have chosen your builder, it’s time to sit back and check if the work is going according to the schedule. Ensure to never change plans midway through the project to avoid delays and cost increases. Once the work is complete, you can enjoy the extra room and extra light flooding through the rear of the house. I would call that a success.

We find that if pre-construction design and planning has been done correctly, the job will go as planned; however, as with any old house in London, surprises are not to be wholly discounted.
