Your house expansion will be built as part of our company’s wide variety of building and remodeling services. The construction process often begins with clarifying the client’s requirements, during which we also provide suggestions for the design and selection of materials. For example, we can create a plan and submit the relevant paperwork for requesting a construction permit based on the information that has been provided and is mutually agreed upon. Next, we begin building your addition and even modifying your property.
The building of an extension typically involves the following steps, though they may vary depending on the style of extension, the materials used, and the client’s preferences:
✓ Dismantling and getting ready
✓ Building a foundation of floors
✓ Ventilation and insulation in the basement
✓ Construction of a concrete floor
✓ Adding steel trusses and columns and strengthening the facade
✓ Protection from fire for steel columns and beams
✓ Installing wooden window and door frames
✓ Installing drainage pipes to allow rainwater to be drained
✓ Erecting timber frame walls and insulating them
✓ Drywall and OSB for the dry-lining
✓ External wall masonry
✓ Building a timber roof framework and insulating it
✓ Putting up drywall on a frame made of wood
✓ Roofs works
✓ Use drainpipes to connect the drainage system
✓ The installation of electricity
✓ Installing radiators for heating
✓ Work with plaster
✓Putting skirting boards and laying down laminate
✓ Painting the extension’s walls and ceilings
The cost is a significant consideration when intending to increase your living area. The size and design of the addition, the number, size, and kind of windows and doors, the roof and foundation, underfloor heating, the types of lighting, and the finishing materials chosen all impact the cost estimation. You can pick the best extension model and material options based on your preferences and financial constraints. Our business will be able to assist you in making your extension decision and provide a quote for the labor and material costs.
