A Local Property Design Specialist Who Understands What Is Possible

Every extension and refurbishment project is different and is subject to local authority planning regulations or conservation rules.

Our experienced team can assess your needs and provide accurate advice about the feasibility of your planned project. Because we are local to you, we offer an insightful understanding of the area and are well-acquainted with planning regulations and restrictions that could impact your planned work.

We are on a list of established architects who have carried out a significant amount of work in the Hampstead Garden Suburb. As such, we are highly regarded for the quality of our development advice and pride ourselves on our ability to present achievable design proposals that comply fully with regulations.

How We Work: The RIBA Framework

All our projects follow the Royal Institute of British Architects (RIBA) project management and service framework to give our clients clarity about what is possible within their agreed budget, as well as clearly defined goals and timescales.

Each extension or refurbishment project follows six key stages:

1) Initial Consultation

As soon as we have discussed your project objectives, we will provide you with a quotation for your acceptance. We will arrange digital scanning and measuring equipment to be used to create a CAD drawing of the design.

3) Planning

Our architect will collaborate with you to ensure that all your needs are met and submit planning applications to the local authority (or work within permitted development rights, where applicable).

5) Construction

At the beginning of construction, we collaborate closely with engineers, service engineers, and adjoining property owners- where applicable, to get party wall agreements. In addition, we maintain quality and specifications, and ensure that plans are met. Furthermore, we ensure to keep you informed throughout.

2) Creating A Concept

We’ll evaluate your briefs and propose creative ideas from your extension or refurbishment within your desired budget that gives you the most value.

4) Technical Design

All successful residential extension or refurbishment architects rely on high-quality technical drawings, which form the bulk of our work. We produce multiple drawings, schedules, and specifications which are tendered to builders for commencement on-site.

6) Handover

We will then transfer responsibility for the completed project over to you or your client, ensuring all necessary documentation and information is provided for maintenance and future use.

Peter Ungar is a gifted architect with great vision. He developed plans with great imagination and sensitivity to add a new annexe and reconfiguration of a house and surrounding areas that included rest and recreation areas and wonderful creative use of the spaces that were there. He was inclusive of our needs and requirements, showed enthusiasm for the work and stayed within our budget.
His professionalism is worthy of the highest praise.

Giselle WolfClient

Working with Ungar Architects was an absolute pleasure from start to finish. Peter approached our project with a great deal of passion and care and was personally involved in all aspects of planning and delivery. It was a very challenging scheme so this attention to detail was crucial and we are thrilled with the final result. We wouldn’t hesitate to recommend Ungar Architects and look forward to working with them again the future.

Steph ThrasyvoulouClient

The designs and attention to details that we received from Peter at Ungar Architects were of the highest standards and far exceeded our highest expectations. Peter interpreted our needs and transformed our house into our dream home. Any possible stress from planning through to construction was removed thanks to their guidance and excellent project management of the contractors. Our 12-month project was delivered on time and within budget. I have recommended Ungar Architects to family and friends without a seconds thought. Great Job and Great Service.
