Consulting your needs

Prior to every project, we conduct a full, free, initial consultation with the customer. This meeting gives us the chance to accurately define the service required and discuss any specific requirements, designs and material choices. We will also take this opportunity to determine budget restrictions, take measurements and identify the preferred method of payment.

All-encompassing services 

To provide an all-encompassing service for each and every customer, we have developed expertise in various fields. Unlike other specialised companies who will only complete one aspect of the build, we also complete additional interior work such as painting, general decorating, plastering, plumbing and electrical installations. Additionally, as part of our planning and design service, we complete architectural drawings, meaning you do not have to outsource any aspect of your project.

Completing groundwork

The team at Octagon Construction Ltd is fully trained to carry out any groundwork necessary. Primarily, our groundwork is completed alongside our building or construction projects, especially when working on new builds. However, we also carry out groundwork separately for other companies, businesses and individuals.

Long-lasting quality guaranteed

Upon completion of the job, our team will make sure that the work meets our high standards and complies with all regulations before signing it off. Such is the confidence we have in the quality of our materials and the standard of our workmanship. Every job that we complete is accompanied by a comprehensive 12-month guarantee. A year after the building work was finished, we will return to your property and conduct a full assessment to ensure that it still complies with the relevant regulations and falls in line with our working standards.

'In March 2014, having accepted the quotation and signed the FMB contract, construction began on my 4m x 4m (approximately) lean to extension. The ground had to be piled after removing an existing conservatory as the house had been retrospectively piled some years before. A specialist company was employed for this by Octagon Construction Ltd and the base along with suspended floor was rapidly completed. We had agreed staged payments and these were not varied and were requested on completion of each stage. The weather was atrocious over the next couple of months but the work was completed in a timely manner and we are very happy with the final result. All certificates for work done were received when the stages were completed. The site was kept as tidy as possible in a smallish garden and work was carried out safely at all times. Communications were good and a couple of small changes were incorporated into the original price.

I can recommend this company to anyone doing a similar job.'
