Is basement development viable?

Yes, but it’s complex. Expect structural, flood, and geological studies alongside detailed negotiations with Camden officers.

Do you work with developers?

Absolutely. We specialise in unlocking challenging sites with designs that balance feasibility, planning strategy, and architectural quality.

How do you handle neighbour sensitivities?

We take a proactive approach — clear visuals, early dialogue, and policy-aligned justifications help secure support and minimise objections.

Can you integrate sustainability upgrades?

Yes. We design with energy efficiency in mind, from improved insulation and glazing to passive cooling and renewable energy systems.

What’s the typical ROI for a Hampstead project?

Design-led refurbishments and extensions often deliver a 1.5x–2x uplift on cost, especially for heritage homes.

Hampstead Architects

Boutique, design-led Hampstead architects for aspirational homes and developer projects in NW3 — crafted by DOR Architects. We specialise in elegant, context-sensitive architecture supported by practical planning expertise and build-ready documentation, ensuring your project is as refined as it is achievable.

Introduction: our approach as Hampstead architects

Architecture in Hampstead is a conversation between past and present. From Georgian terraces and Arts & Crafts villas to discreet mews houses, every street in NW3 carries its own story.

At DOR Architects, we design homes and developments that balance bold interiors with respectful exteriors, blending design flair with an expert understanding of local planning policy. Whether you’re modernising a family home, exploring a backland infill plot, or managing a listed renovation, we bring the clarity and technical precision to deliver confidently.

Where we work in Hampstead

Our experience spans the full range of Hampstead’s unique settings:

Hampstead Village – Listed townhouse refurbishments, sensitive internal reconfigurations, and discreet rear extensions
Fitzjohn’s Avenue, Downshire Hill & Frognal – Heritage-sensitive renovations and façade-led design
South Hill Park & Parliament Hill – Garden-facing architecture and rooftop additions mindful of protected views
Hampstead Heath borders – Height-sensitive extensions and eco-conscious garden studios
Mews and backland sites – Creative infill housing with challenging access and high expectations for design quality

Wherever your site is, our relationships with Camden Council planning officers and heritage consultants ensure that your proposals are persuasive, compliant, and compelling.

Planning and heritage in Hampstead

Planning in Hampstead is defined by layers of regulation: Conservation Areas, listed properties, ecological designations, and strict controls around the Heath and Parliament Hill.

Key planning considerations include:

Listed buildings (Grade II & II*) – Tight restrictions on internal and external alterations
Conservation Area controls – Height, rooflines, materials, and window profiles under scrutiny
Daylight, privacy, and massing rules – Particularly challenging on mews or backland plots
Basement restrictions – Requiring structural, flood risk, and ecological assessments
Height and view corridors – Protecting strategic sightlines near Hampstead Heath

To navigate this complexity, we integrate BIM-driven design with persuasive planning submissions that include daylight and sunlight reports, heritage impact assessments, and proactive dialogue with officers.

Lifestyle, sustainability, and return on investment

Thoughtful design in Hampstead achieves more than just square footage — it enhances lifestyle, wellbeing, and even property value.

Lifestyle: From seamless indoor-outdoor connections to improved natural light, good design creates homes that feel generous and calm.
Sustainability: We integrate discreet solar panels, high-performance insulation, and efficient systems that lower operational costs while respecting heritage constraints.
Return on investment: Quality design, especially in a prime postcode like NW3, drives measurable uplift in property value and long-term resilience.

Case study: discreet transformation in NW3

One recent project involved the full refurbishment of a Georgian townhouse in Hampstead Village. The brief:

“More light and space — but no visible change from the street.”

Our solution combined:

A modest but efficient rear extension
Internal reconfiguration to optimise circulation
A basement-level study and playroom

The planning strategy focused on restraint and evidence, supported by heritage statements and daylight studies. The result? Swift approval and a home that now feels double its original size — while preserving its historic presence.

FAQs

Do I need planning permission in Hampstead?
Almost certainly. Most properties fall under Conservation Area controls or listing, meaning even minor changes often need consent.

Can I extend a listed property?
Yes, with the right strategy. Sensitive rear extensions, internal reconfigurations, and basement additions are possible when handled carefully.

What are the rules for basement construction?
Basement developments are heavily scrutinised in NW3. Structural, flood risk, and ecological assessments are usually mandatory.

How long does the planning process take?
Typically 8–12 weeks for standard applications. Heritage-heavy schemes or those requiring consultation may take longer.

Do you integrate sustainable design in Hampstead projects?
Absolutely. From discreet solar panels to intelligent insulation strategies, we deliver sustainable upgrades that complement the architecture.
