02 · THE PRACTICE
Design to completion, from a RIBA Chartered practice.
Your Home Architects is a service offered by Vision and Design, RIBA Chartered architects based in London. We set it up so London homeowners can see the whole job in advance, with the price for each service agreed before that service begins.
Architects Registration Board
Architect is a title protected by law in the United Kingdom. Only someone on the ARB register may use it. Registration requires seven years of education and examination, is renewed annually, and can be removed for professional misconduct.
ARB REGISTERED ARCHITECTS
RIBA Chartered practice
Registration is held by the practice, not just an individual. It requires a registered architect in charge, professional indemnity cover, a written complaints procedure and continuing professional development.
VISION + DESIGN LTD
Why the title matters to you
An architectural technologist or designer may be excellent, but is not accountable to a regulator. V+D are Chartered Architects, giving you a complaints route, a disciplinary body and mandatory professional indemnity cover.

03 · THE SERVICE
How we help homeowners in
Lambeth
Fixed-fee architectural services for London homeowners, in Lambeth and every other borough, from a RIBA Chartered practice. Lambeth is Victorian terrace country, from Clapham through Brixton to Streatham, and the side return infill is the move that transforms these houses. Around a third of the borough is protected, and the extra restrictions apply street by street rather than everywhere. We establish exactly what your address allows first, then price each stage before it starts.
Our work here is side return infills and wrap-around extensions on the Victorian terraces around Clapham and Brixton, usually with a rear dormer above where the roof allows it. Each stage priced before it begins.

06 · YOUR ADDRESS, NOT THE AVERAGE
What we check before anything is drawn.
IS YOUR STREET PROTECTED?
62 conservation areas covering around a third of the borough, including Clapham, Abbeville Road, Stockwell Park, Albert Square, Hyde Farm and Leigham Court Estate.
WHAT EXTRA RULES APPLY HERE?
Extra rules apply in named areas including Albert Square, Hyde Farm, Lansdowne Gardens, Leigham Court Estate, Park Hall Road, St Mark's, Stockwell Park and Streatham Lodge Estate, rather than across the whole borough.
WHAT KIND OF HOUSE IS IT?
Victorian terraces across Clapham, Brixton and Streatham, post-war estates and newer flats. The terraces are narrow with a side return, which is where the extra space usually comes from.
WHAT PEOPLE USUALLY BUILD HERE
Side return infills, rear and wrap-around extensions, rear dormers, single storey basements and garden rooms. The side return is the defining Lambeth project.
ANYTHING ELSE THAT AFFECTS YOUR SITE
Basements are limited to a single storey under the existing house in most cases. The Thames frontage and the buried River Effra bring flood risk in parts. Reference: Lambeth Design Guide SPD, August 2023, Parts 4 and 5, and Policy Q11.

08 · COMMON QUESTIONS
Do I need planning permission to extend in Lambeth?
It depends on the street. Lambeth has 62 conservation areas covering about a third of the borough, and a handful of named streets carry extra rules on top. Elsewhere the usual allowances apply and plenty of extensions go ahead without an application.
What guidance does Lambeth judge extensions against?
Its design guide, adopted in August 2023. One part covers extensions and alterations, another covers basements, and both are specific about proportions, materials and the effect on neighbours. Reading it before designing saves time later.
Are basements achievable in Lambeth?
A single storey under the existing house is realistic. Going beyond the footprint into the garden is a considerably harder case, and the guidance is specific about what will and will not be supported.
