Design Services Overview

We have found in recent years that the number of homeowners carrying out their first residential extensions and building refurbishments is increasing exponentially, and we have much experience in working with inexperienced clients and guiding them along their first Architectural adventure. In addition to this, many of our clients have some experience in the construction industry and can consist of property developers who have more direct instructions and know exactly what they want. At Quatrefoils we will tailor our level of service to suit your requirements and have good knowledge across the construction sector.

As we specialise in all aspects of construction projects from design and specification to contract administration and project management, we can provide quality advice on your project, and can assist you with obtaining the necessary statutory planning and building regulations consents, as well as produce detailed technical drawings for tender and construction. At Quatrefoils we work closely with Structural, Mechanical and Electrical Engineers who are available on request to provide their input as required with each project. For a no obligation consultation, feel free to contact one of our design team.

We work with both private and public sector clients on projects of varying sizes.

Our complete design service aims to tackle all of the stages throughout a construction project, from initial design, planning and building control applications and also can include building surveying and project services in producing technical specifications for tendering purposes, taking the role of contract administrator in the tender process, and then running the project on site carrying out valuation and issuing certificates for payment, right the way through to completion and agreeing the final account with the contractor.

Planning and Building Regulations Drawings

We work closely with a number of the Local Authority Planning and Building Control Departments, as well as Private Approved Inspectors. Our team has an excellent understanding of local planning factors and considerations, and strive to keep up to date with the latest updates and changes to the Building Regulations. Our success rate for both planning and building control approvals is exceptionally high. 

We are familiar with the planning process and will be able to tell you if your building project will require planning permission, and whether you will be able to take advantage of current planning rules and streamline the planning process such as permitted development. If your project requires planning drawings, we can assist and carry out a measured survey and produce existing and proposed plans and elevation drawings with notes and submit a planning application on your behalf. We will monitor the planning application progress, liaise with the planning case officers and make any necessary amendments to the drawings and application as necessary to give the application the best chance of approval.

In addition to Planning Permission, the other main statutory approval required for almost all building projects is Building Regulations approval.

Building Regulations approval can either be obtained from the Local Authority Building Control Department or through Approved Building Control Inspectors. Quatrefoils Design Team and Building Surveyors have extensive construction knowledge, and can produced detailed technical drawings with construction notes for Building Regulations approval.

We are familiar with the Building Control Approved Documents and are able to submit a detailed Building Regulations application on your behalf and liaise with Building Control in attending to any queries or amendments necessary.

Refurbishment Projects

Almost all of our design projects involve some form of refurbishment, whether part of an extension or larger scheme or involve remodeling and improvements to an existing building. Quatrefoils work on refurbishment projects of all sizes for both private residential / commercial clients and public sector clients.

Our surveyors and designers are experienced in specification writing and couple our knowledge of buildings and construction with our design skills to maximise the potential of each property and provide inspiring design solutions. If you are planning a refurbishment project, get in touch with one of our team members to discuss in more detail and hopefully we can provide value to your scheme.

Should the plans get rejected for any reason, we would carry out the necessary amendments to guarantee the plans are passed to the best of our ability.

Residential New Builds

Quatrefoils adopt a fresh approach when it comes to New Builds and like to work one on one with the client to ascertain a very detailed design brief in order for us to tailor the design to suit the needs of each client. We often recommend initially appointing us to carry out a feasibility study once the initial brief has been determined which will highlight potential challenges, costs, limitations and considerations.

Our design service for New Builds can be flexible and either involve a complete design service from inception to completion or just take the project to planning / building regulations stage. We work closely with Structural, Mechanical and Electrical Engineers who are often required in New Build Projects. Contact a member of our friendly team for an initial chat about your planned project.

Feasibility Studies and Reports

A feasibility study is a procedure carried out in the early stages of a project, usually once an initial design brief has been determined. The purpose of the study is to ascertain how viable the project is, looking at potential limitations, budget costs, design options and other important factors that should be defined and determined before the project progresses too far.

At Quatrefoils we can assist in undertaking feasibility studies for your project, we will carry out an in depth review of the project, look at design options if necessary, consider if an environmental impact assessment will be required or planning permission, as well as all associated factors and hurdles that form part of the building process for that particular project. Information and results will be presented in a detailed report in order to enable the client to determine whether to proceed with the project or not.
