Build Extensions London
Quite often it just makes more sense to add an extension onto the house rather than have to pack everything up, sell the house, buy a new one, pay moving expenses, and unpack. Build extensions London has become the best way to enlarge the home and there are a lot of decisions that have to be made when undertaking this level of home improvement. Some items that have to be considered include:
- Obviously, for these domestic extensions, there has to be room on the existing property if the new extension is to be at ground level. If the extension is going to require a raised room, the foundation must be structurally sound to support the additional weight.
- Another consideration is that the additional brick or stone matches the materials on the existing structure. Most homeowners don’t keep enough of a supply of the original materials to add an entire room, but it needs to match in color and texture.
- In addition to matching bricks or stone, the roofing materials need to match the material on the adjoining roof. Generally, over the years the colors on the shingles do change slightly, so as close a match as possible is recommended.
- The local building regulations are generally handled by the home extension builder, but for homeowners who are doing a great deal of the addition themselves, they must make sure that they fully understand the requirements of the regulations and all permissions they need to obtain before beginning construction.
There are a number of home extension builders in London that have experts qualified in various trades to help with all the decisions the additional space. Some of these domestic extensions absolutely would require carpenters, brick layers or stone masons, roofers, and painters, but some of them require additional bathroom facilities (or even a small kitchen) and for those plumbers enter the picture.

Once the homeowner has decided that a domestic extension is the solution, the home extension builder has to be selected; there are some tips in picking the best one to ensure that the extension meets all the required codes. Some actions to include are:
- Check with the local real estate agent for recommendations. They often hear about the best, the worst, and all the ones in between, and they can help save time and money in steering the homeowner away from the ones with substandard reputations.
- Make sure to also ask other neighbors, family members, co-workers, and friends for experiences they have had with various companies who have the laborers to complete the building extension. One thing will become clear after checking with several sources – the contractors that do a great job, and the ones to avoid.
- Another tip is to be sure to check the references of the contractor.
- Find out if they stayed on schedule and under budget consistently for their other jobs.
- Also find out if their previous customers were satisfied with the job or if additional items had to be redone after the job was completed.
- Finally, determine how responsive the contractor was in getting any concerns addressed or changes made.
- Make sure all of the licenses for the trades from the contractor are all up to date, and they all have the proper education. Be sure to verify with the License Board, and their specialty areas are correctly identified.
- Finally, verify that the contractor carries all the proper insurance for all aspects of the job.
