About Home Extension Designs

Home Extension Designs was established in Hertfordshire in 1988.  They have been working successfully in the residential architectural sector for over 25 years on building and planning projects ranging from simple internal alterations through to single storey home extensions, multi-storey house extensions, loft conversions and new dwellings.  Whether you require a simple conservatory or porch, a major two-storey extension or complete new home, Home Extension Designs’ skill and experience will successfully guide your concept from start to a truly elegant completion.

Rather than move to a new house and incur substantial legal costs, why not consider your current home?  Home Extension Designs can usually achieve the space you need.  You may need a larger lounge, kitchen or bedroom; an extra room for the kids to play or relax in, a study, utility, bathroom, toilet or even an en suite.  The Home Extension Designs Team will transform your home into a place of enjoyment, a area of relaxation and, above all, a beautiful new home to live in.  Home Extension Designs have the vision and expertise to turn your dreams into reality, so there is no need to move home. They  use the latest Computer Aided Design technology (CAD), to produce all of their drawings, with optional coloured computerized 3-D images to help you visualise how the final design will look.

Home Extension Designs understand what the local authorities stance is on various design and build elements.  Welwyn and Hatfield Borough Council have very different planning regulations to say Decorum,  and by understanding these differences enables us to present your plans correctly, negotiate and act swiftly on any modifications and alteration that may be required, and help promote the rapid approval and completion of your project.

Feasibility

A free initial on site consultation from one of their experienced members of staff will be the starting point.  At this initial meeting they will carefully listen to your requirements, advise you on other creative options you have and help you to understand and decide upon the best solution for you and your budget.     They will then discuss the various Council permissions, regulations and requirements which may, or may not be needed; budget the build costs and other procedures, and explain how their fees structure works.   After discussing your options and agreeing a way forward, they will prepare a free quotation detailing all of the project’s milestones, examples of their work and any other relevant information.

Your project will have started; you can relax knowing that it is in the hands of Home Extension Designs and you are being smoothly and professionally guided to a successful completion.

Planning

Home Extension Designs are very experienced in the Planning area and when initially meeting with you they will discuss the various Planning requirements particular to your Local Authority.  Many projects do not need Planning Permission and they will happily advise you of what is and is not applicable to your project.  If Planning Permission is required, they will advise what the Council will allow and discuss the procedure in more detail.  As part of their service, Home Extension Designs  will complete all the necessary paperwork and forms, submit the application to the Council and liaise with them to secure a decision.

Building regulations

As certain projects do not need Planning Permission (see planning), you will nearly always need Building Regulations Permission.  This is where detailed construction drawings are prepared, indicating construction methods for foundations, floors, walls, roofs etc.   Some small projects do not require Building Regulations Permission, but to be sure that the construction is adequate, and in order to obtain competitive builders prices, it is necessary to have construction drawings.  If specialist finishes, designs or materials are needed or preferred, we can source and detail these on the drawing and accompanying information.   As part of their service Home Extension Designs would obtain and complete the relevant application forms and submit them to the local authority.  Home Extension Designs liaise and negociate with them on your behalf to secure the approval.

Contractor / Builder

Deciding on which contractor to use is probably the most worrying part of the project.  The building work is the most expensive part of any undertaking of this nature and careful selection of the contractor is critical.  Home Extension Designs  has built excellent relationships with many building contractors, in whom we trust to carry out your projects through to completion.  Having a sound history and excellent relationship with them, makes the whole process smoother and easier for you.  Any problems which may arise, can be swiftly dealt with so that your project can continue to completion.
