Project Stages

Typical stages of services for a design project

Initial Design

KMASS visit the property, take sufficient detail to, and prepare plans and elevations of the existing and proposed building and liaise with you prior to commencing the next stage.

Planning Application

Following initial design, we would prepare and submit proposals for Planning Application to local authority. Applications are usually decided within 8 weeks of the application being validated. More complex applications may take longer from validation of the application.

Building Regulations Application

Once planning approval is to hand, we would prepare detailed drawings & structural calculations suitable for the purposes of a Building Regulations submission. These drawings will also assist with contractors pricing and construction. Time taken to gain building legislation approval varies. A full plan application takes 5-8 weeks.

Party Wall Matters

When building works are notifiable under the Party Wall etc Act 1996, we would prepare & serve notices, prepare schedules of conditions, and, if the adjoining owner(s) have dissented to the notice(s), liaise with Adjoining Owner’s Surveyor(s) as necessary and prepare and serve an Award. The Act sets out statutory periods for the service and response to notices.

Contract Administration

As contract administrator, KMASS could obtain quotations from builders, provide a report to assist you in selecting a builder, administer the contract, advise you and certify payments to the builder as necessary.
