Renovating your house/flat, extending your home or developing a new property.

Permitted Development Scheme

This guidance reflects temporary increases to the size limits for single-storey rear extensions that must be completed by 30 May 2019, and the associated neighbour consultation scheme.

An extension or addition to your house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions:

  • No more than half the area of land around the “original house”* would be covered by additions or other buildings.

Planning Applications

Most work carried out to the external parts of a property (and in some situations the internal parts) requires some form of planning application to be made. You’ll probably need planning permission if you want to:

  • build something new
  • make a major change to your building – e.g. building an extension

Building Control Drawings

Sometimes referred to as Building Control and commonly considered yet another hurdle to jump over before your project can begin, this stage is important as it serves to ensure your safety.

By far the most technical aspect of any project is the Building Regulations approval stage. This requires intricate and precise drawings that will detail exactly how the building will be constructed. At times, it will also require the input of other industry professionals, such as a structural engineer.

Consultant Liaison / Reviews

Depending on the size of your project and in order that the scheme can be fully designed, it is usually the case that other consultants will be required, such as structural engineers, mechanical and electrical consultants, quantity surveyors, party wall surveyors and project managers. As part of our role to coordinate the design of the whole scheme, we would liaise with the design team consultants to develop a coordinated and detailed tender pack of documents.

Tender Documentation

To obtain the most suitable contractor to carry out your works, it is advisable to invite a number of different contractors to “tender” for your works. In order that a contractor can accurately assess the works that are to be undertaken, a detailed set of drawings and specifications needs to be provided, including, where necessary, structural or mechanical designs and calculations.

Using this information, the invited contractors will provide a competitive quote for the works. We will assess these tender returns, and make a recommendation as to how to proceed.

Party Wall Agreement

Barry Stott-Brookes is a party wall surveyor with over four years’ experience in the London and South East property and construction sector. We undertake residential party wall work in London and the South East. The Party Wall etc. Act 1996 is in place to provide clear guidance and restrictions on what works can be carried out to a party wall/structure, and how. As adjoining neighbours have an interest in the party wall or structure between their properties, it is required that notice be provided for most works to that wall/structure. The role of the party wall surveyor is to mediate how these works are carried out.

On Site Supervision

The architect’s role during the construction period is usually to carry out periodic observations of the works to check for compliance with the contract documents. This often results in amendments to details or designs to overcome unforeseen site conditions.

Following the observations, and often in collaboration with a quantity surveyor, the architect is responsible for issuing the payment certificates and providing any instructions related to additions or omissions to the contract works.

Contract Administration

Sometimes, in collaboration with a quantity surveyor or project manager, we will assist in the drafting of an appropriate contract for the client and the contractor to sign.

The architect is then responsible for administering the contract, thereby ensuring that the building work is executed in accordance with the construction pack of documents.

Build Management

Contract administrator for construction contracts

In the construction industry, the contract administrator is the individual responsible for administering the construction standard contracts.

The contract administrator may be the project architect, but could also be the lead consultant from our team, the cost consultant, a specialist consultant, a client representative or employer’s agent, the project manager or an engineer. On a construction management contract, the role of contract administrator might be attributed to the construction manager, and on management contracts the management contractor will perform the role of contract administrator.

Completion Certificates

Nearing completion of the construction works, the architect will assess the building work for compliance with the contract documents (also known as “snagging”) and, if complete, will certify the work as “practically complete”, which is authorised by means of a Practical Completion Certificate. At this stage, 50% of any financial retention is released to the contractor, and the rectification period commences.

Full Construction Package

Although a tender package of works is very detailed, it is only intended to be sufficient for a contractor to provide a quotation. On larger schemes with more complex detailing, additional information/detailing may be required in order that the works can be constructed on site.

As and when required, we provide this additional information, usually prior to works commencing on site or sometimes as work stages are reached.
